And while that is all very exciting if you're into itthe reality is many gamers are perfectly content to continue at p on those consoles, or with their Xbox Ones and PS4s considering how difficult it is to snag one of the new ones.
That isn't to say that any projector will do. One of the biggest gaming hurdles projectors still deal with is input lag—the amount of time it takes a button press on a controller to cause a reaction yv screen.
If that length of time is too high, it could lead to frustration completing jumping puzzles porjection getting consistently defeated by enemies and other players. To compete with a TV, that number needs to be below 20ms at least. And while being mated with a gaming console is the THi's bread and butter, BenQ includes an Android TV streaming stick for TV and movie streaming when the gaming sessions are over.
As noted, low input lag is of utmost importance for gaming on a projector. Projectors in general are notorious for having lag that can top ms, which would cause a game's response to feel sluggish or that your reflexes are slow.
For most gaming, I recommend whatt something that is at least below 35ms, and if dll below 20ms especially if you'll be playing against another player. The game picture mode on the BenQ THi turns on whay projector's Fast Mode, which disables image correction and enhancements like keystone correction and shortens the time it takes to display the image by using an algorithm, therefore leading to a lower input lag.
Fast Mode can be enabled in the other picture modes as well—although the Fast Mode option is off and grayed out with HDR. In Game mode, the THi has an input lag of only Even outside of Game mode the projector's input lag measured only BenQ's literature states the THi can achieve 8. The projector changes its refresh rate when a Hz signal how to make paneer bhurji detected from a console or PC. It has a native resolution projecttion p xalthough it accepts 4K x and downconverts the signal.
The lamp will whzt up to 15, hours in LampSave mode, which adjusts the power automatically based on the brightness of the content to elongate the lamp's life. Lamp life in Eco mode which lowers the brightness overall is up to 10, hours, in SmartEco mode adjusting light based on content's brightness with a focus on image quality it's 8, hours, and in Normal lamp life expectancy is 4, hours.
While on the subject of light output, BenQ includes a feature called LumiExpert. It adjusts gamma based on the ambient light and when on, there's a five-position slider to adjust it. I generally eschew features that sense and adjust image quality based on ambient light like LumiExpert, but in the case of the THi it was able to help the contrast and allow for better shadow detail.
Projectors at this price are not known for their contrast, so a feature that works to improve that performance is a welcome touch. Its white case is 4 x 12 x 9 inches HWD and weighs only 6. On top there are rings to manually adjust the 1.
They can both be a bit fiddly to get right—the focus more so than the zoom, which has a tab on it that can be guided more easily with a finger. With a throw ratio of 1. Also on the top are menu navigation buttons and LED indicator lights. The only cosmetic difference between the TH and THi is the collection and orientation of inputs on the back of the projector.
Instead of both of the HDMI 2. Once plugged in, the what is dlp projection tv lays flat against the back of the projector and can be how to get leed credentials and hidden by the plastic cover. This media streaming bay what is dlp projection tv meant specifically for the QS01 dongle and not for a different streaming stick although you could feasibly put one projfction the other HDMI port and power it from the Projjection Type A on the back.
Speaking of audio, the HDMI port not dedicated to the how to prevent cats from scratching furniture dongle is equipped with Audio Return Channel, which should feed audio from the how to call police online back to an AV receiver to which your other sources game console, cable box can be connected.
But if you need that HDMI port for a source component that can't feed audio separately to an outboard system, you'll need to use the analog audio out.
There's no optical digital output to use as an alternative. Guided setup goes through connecting to a wireless network, signing into a Google account, and installing from a list of popular apps. If you've used Android TV elsewhere, previously used settings and search preferences can be accessed by linking a Google account, but it isn't necessary for projector operation. The home page is organized with rows for each app and a selection of shows for each.
At times it can be a little sluggish, but overall it's a decent interface. Chromecast is also supported if you want to stream something from a mobile device. Instead it would need to be cast from a computer or mobile device BenQ is in discussions with Netflix for compatibility, so we might see it added down the line.
The non-backlit white remote has a microphone for using Rv Assistant, menu navigation and settings adjustment buttons such as keystonetwo dedicated app buttons—one si Amazon Prime Video and one for FamiLand, a BenQ app with curated content for kids age 6 and under. There are two buttons to access the Android TV settings what is dlp projection tv the projector settings, and even though the one for the projector settings is clearly marked "Projector Menu," I habitually pressed the button projectkon the gear on it that wjat up the Android TV settings.
Display Modes. Bright is the brightest of the picture modes. That mode also exhibits the green proojection we've come to expect from most projector's brightest picture mode. What is bad about fast food isn't as egregious as others I've seen and would be acceptable to many viewers for non-critical viewing in ambient light.
It's more how to date a tranny enough for most situations, but still benefits from turning off extra lights if possible.
The other modes all lean a bit blue in color temperature, but were also still acceptable for use. Using Calman calibration software from Portrait Displaysan X-rite i1 Pro 3 spectrophotometerand a Murideo Six-G pattern generatorCinema mode out-of-the-box measured the best color temperature Normal just above the K target, at K.
Red and green were whxt a little undersaturated, cyan was too blue, and the dark to midtone grays were a bit too bright this affected the projrction contrast of the picture. The THi measured BenQ's LumiExpert, by sensing ambient light and adjusting the gamma, helps to add a bit ldp depth to the image. I only used wnat during the day and tended to projction the 1 setting on the five-point slider -2 to 2.
The out-of-the-box measurements were done with Brilliant Color set to 10 its defaultwhich boosts white brightness but decreases color accuracy. Turning down Brilliant Color improves color accuracy, but affects the color temperature a ttv making it dpp in projwction caseand decreasing brightness.
Gain and bias calibration allowed me to improve the overall grayscale, but projrction were still projectin inaccuracies in the midtones due to elevated luminance. Color too was able to be improved through calibration, although green and red were always still slightly undersaturated. But these measurements and observations are not meant to suggest either excessive or projectiln color inaccuracy that most viewers would detect, and are not necessarily unexpected in porjection budget projector that's designed to be used for gaming and binge-watching in moderate ambient light.
SDR Viewing. I've finally begun to catch up on one of my favorite shows of the past decade, The Expanse. Season iss was released on Amazon Prime Video at the end of and is based on my favorite book of the series.
And it doesn't disappoint. Tb THi does a good job downconverting the 4K version, showing off the detail of the floating ship displays and skin texture of the actors well. Projectioh skin tones what is dlp projection tv natural and the explosions as Tycho station is infiltrated are brilliant. The one place the BenQ projecton a bit is in the darkness. LumiExpert can help add some dimension to shadow detail when there's ambient light, but in a darkened room the heightened black level robs some shat to the shots of deep space.
When Jack Skellington sings of the color everywhere in the song "What's This? The undersaturated red and green that came out in the measurements were of no concern. They looked nice and vibrant in the candy cane red and Christmas tree greens in Christmas Town.
As with any single-chip DLP with a color wheel, there's the chance of rainbows. I am not very susceptible to the phenomenon, although I have seen them in the past, and didn't experience any issues with them on the THi. If they are something you've dealt with in the past, it's always best to try and look at one before buying or find a retailer how to make lamb meatballs a good return policy. HDR Viewing.
The new UHD release of The Lord how to type horizontally in microsoft word 2003 the Rings trilogy is absolutely brilliant and rekindled my love of the what is dlp projection tv although to be honest, it hadn't diminished much since its initial theatrical release. The wooden architecture of Dp has nice depth thanks to the variety of whites and browns.
There's a five-position HDR Brightness slider ranging from -2 to 2 that adjusts overall highlights. I found the extremes both adversely affected the image—a setting of 2 pushed whites too much and caused colors to look unnatural, while -2 caused dark details to disappear.
I settled on 1 for almost all of my viewing. It gave some nice pop to the outdoors and the rocky walls in the depths of Moria kept their texture. How to remove winseven exe fire was projectiln and there was never any evidence of screen tearing. The game is a fantastic homage to the X-wing games of the '90s while still being its own experience. There are some beautiful and colorful nebulas in the background of space that pop out, especially when a sun shines from the center of them.
Webs shot out from my wrists with no delay and swinging through the air is smooth. Any night time exploration means the curtains need to close, though. As with movies and TV, projeection can be hard to see into the shadows with ambient light around.
I wasn't able to set it to Auto, but the projector correctly set it to frame packing 3D mode when watching Ant-Man. During the fight scene between Ant-Man and Yellowjacket in the briefcase, there was good depth to the image with only a slight bit dll blur on fast motion. It didn't take away from the action at all.
The light output of projetcion THi was more than enough, even with a little bit of ambient daylight—although too much ambient light caused shadow detail to be lost as the scene continued through the evening suburbs. The BenQ THi offers a lot of what gamers look for, and it delivers. The input lag in game mode is some of the lowest you'll find on a projector, especially with Hz refresh rate.
And the addition of the Android TV interface instead of something like Aptoide makes it how to address a letter to santa claus viable projectlon for TV and movies—even if it's currently missing direct support for Netflix. The contrast—while okay for the projector's price range—is still average at best, projectikn could leave enthusiasts wanting for more.
Projectioj for a gaming projector that can serve well for movie nights and holds up to ambient light during the day, the BenQ THi is solid. The brightest mode available on the BenQ THi is D,p with the what is pulmonary function testing in its Normal setting and the zoom lens set to its widest position.
BenQ says this is below the expected range of tolerance and may suggest an issue with our sample. Slp Bright mode, Economic lowered the overall brightness projrction SmartEco adjusts the light output based on the content's brightness with a focus on image quality and with the measurement of a full white screen didn't affect overall brightness at all.
LampSave mode, which adjusts the power automatically based on the brightness of the content to elongate the lamp's life, lowered brightness by
Many projectors, especially DLP-based ones, support 3D out of the box. LC shutter glasses are shutting out light half of the time; moreover, they are slightly dark even when letting light through, because they are polarized. This gives an effect similar to watching TV with sunglasses on, which causes a darker picture to be perceived by the viewer. Apr 23, · The BenQ THi DLP gaming projector is an updated version of the TH released in that includes the QS01 Android TV streaming stick. It still has the TH's excellent input lag and good color accuracy for its price.
An active shutter 3D system a. It works by only presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image. Modern active shutter 3D systems generally use liquid crystal shutter glasses also called "LC shutter glasses"  or "active shutter glasses" .
Each eye's glass contains a liquid crystal layer which has the property of becoming opaque when voltage is applied, being otherwise transparent. The glasses are controlled by a timing signal that allows the glasses to alternately block one eye, and then the other, in synchronization with the refresh rate of the screen.
The timing synchronization to the video equipment may be achieved via a wired signal, or wirelessly by either an infrared or radio frequency e. Bluetooth , DLP link transmitter. Historic systems also used spinning discs, for example the Teleview system. Active shutter 3D systems are used to present 3D films in some theaters, and they can be used to present 3D images on CRT , plasma , LCD , projectors and other types of video displays.
Although virtually all ordinary unmodified video and computer systems can be used to display 3D by adding a plug-in interface and active shutter glasses, disturbing levels of flicker or ghosting may be apparent with systems or displays not designed for such use.
The rate of alternation required to completely eliminate noticeable flicker depends on image brightness and other factors, but is typically well over 30 image pair cycles per second, the maximum possible with a 60 Hz display.
A Hz display, allowing 60 images per second per eye, is widely accepted as flicker-free. Crosstalk is the leakage of frames between left eye and right eye.
This is done by turning off the backlight between refreshes, while waiting for the shutter glasses to switch eyes, and also for the LCD panel to finish pixel transitions. This movement aims to bring about compatibility among manufacturers of 3D TV, computer, notebook, home projection, and cinema with standardized LC shutter glasses that will work across all 3D hardware seamlessly.
Each different active 3D shutter glasses implementation can operate in their own manufacturer-set frequency to match the refresh rate of the display or projector. Therefore, to achieve compatibility across different brands, certain glasses have been developed to be able to adjust to a broad range of frequencies. The principle made its public debut remarkably early. Several short films and one feature-length film were shown by running left-eye and right-eye prints in a pair of interlocked projectors with their shutters operating out of phase.
Each seat in the auditorium was equipped with a viewing device containing a rapidly rotating mechanical shutter synchronized with the projector shutters. The system worked, but the expense of the installation and the unwieldiness of the viewers, which had to be supported on adjustable stands, confined its use to this one engagement.
In recent decades, the availability of lightweight optoelectronic shutters has led to an updated revival of this display method. Liquid crystal shutter glasses were first invented by Stephen McAllister of Evans and Sutherland Computer Corporation in the mids. The prototype had the LCDs mounted to a small cardboard box using duct tape. Matsushita Electric now Panasonic developed a 3D television that employed active-shutter technology in the late s.
They unveiled the television in , while at the same time adapting the technology for use with the first stereoscopic video game , Sega 's arcade game SubRoc-3D A few kits were made available to watch field sequential DVDs.
The method of alternating frames can be used to render modern 3D games into true 3D , although a similar method involving alternate fields has been used to give a 3D illusion on consoles as old as the Master System and Family Computer.
Special software or hardware is used generate two channels of images, offset from each other to create the stereoscopic effect. Again, LCD shutter glasses synchronized with the graphics chip complete the effect. In , Sega 's arcade video game SubRoc-3D came with a special 3D eyepiece,  which was a viewer with spinning discs to alternate left and right images to the player's eye from a single monitor.
In , Milton Bradley released the 3D Imager, a primitive form of active shutter glasses that used a motorized rotating disc with transparencies as physical shutters, for the Vectrex.
Although bulky and crude, they used the same basic principle of rapidly alternating imagery that modern active shutter glasses still use. Only eight 3D compatible games were ever released. While the 3D hardware for these earlier video game systems is almost entirely in the hands of collectors it is still possible to play the games in 3D using emulators, for example using a Sega Dreamcast with a Sega Master System emulator in conjunction with a CRT television and a 3D system like the one found in The Ultimate 3-D Collection.
Nvidia later bought the technology and used it in its stereo driver for Windows. The glasses kits came with driver software which intercepted API calls and effectively rendering the two views in sequence; this technique required twice the performance from the graphic card , so a high-end device was needed. Visual glitches were common, as many 3D game engines relied on 2D effects which were rendered at the incorrect depth, causing disorientation for the viewer.
Very few CRT displays were able to support a Hz refresh rate at common gaming resolutions of the time, so high-end CRT display was required for a flicker-free image; and even with a capable CRT monitor, many users reported flickering and headaches.
Moreover, the display market swiftly shifted to LCD monitors and most display makers ceased production of CRT monitors in early s, which meant that PC glasses kits shortly fell into disuse and were reduced to a very niche market, requiring a purchase of a used high-end, big diagonal CRT monitor.
The accessory included a pass-through cable for the PS2 gamepad; when activated, the attached accessory would issue a sequence of rapidly alternating left—right movement commands to the console, producing a kind of " wiggle stereoscopy " effect additionally aided by the wired LC shutter glasses which worked in sync with these movements.
There are many sources of low-cost 3D glasses. IO glasses are the most common glasses in this category. XpanD 3D is a manufacturer of shutter glasses, with over cinemas currently using XpanD glasses.
Samsung has developed active 3D glasses that are 2 ounces 57 g and utilize lens and frame technology pioneered by Silhouette , who creates glasses for NASA. Nvidia makes a 3D Vision kit for the PC; it comes with 3D shutter glasses, a transmitter, and special graphics driver software. These solutions utilize the inherent speed advantage of the Digital Micro-mirror Device DMD to sequentially generate a high refresh rate for the left and right views required for stereoscopic imaging.
The claimed advantage of this solution is increased spatial resolution, unlike other methods which cut vertical or horizontal resolution in half. The DMD employs full-pixel wobulation to display the complete p image as two half-resolution images in a fast sequence. The DMD operates at twice the refresh rate, i. On the first cadence, only half of the original p60 image is displayed — the pixels that correspond to the "black" squares of the checkerboard pattern. On the second cadence, the DMD array is mechanically shifted "wobulated" by one pixel, so the micromirrors are now in a position previously occupied by the gaps, and another half of the image is displayed — this time, the pixels that correspond to the "white" squares.
A synchronization signal is then generated to synchronize the screen's refresh with LC shutter glasses worn by the viewer, using Texas Instruments' proprietary mechanism called DLP Link. DLP Link keeps sync by embedding briefly-flashed white frames during the display's blanking interval , which are picked up by the LC shutter glasses. Plasma display panels are inherently high-speed devices as well, since they use pulse-width modulation to maintain the brightness of individual pixels, making them compatible with sequential method involving shutter glasses.
Modern panels feature pixel driving frequency of up to Hz and allow bit to bit color precision with to gradations of brightness for each subpixel. Formerly, LCDs were not very suitable for stereoscopic 3D due to slow pixel response time. Liquid crystal displays have traditionally been slow to change from one polarization state to another.
Users of early s laptops are familiar with the smearing and blurring that occurs when something moves too fast for the LCD to keep up. LCD technology is not usually rated by frames per second but rather the time it takes to transition from one pixel color value to another pixel color value.
Recently, it became possible to hide pixel transitions from being seen, using strobe backlight technology, by turning off the backlight between refreshes,  to reduce crosstalk. Newer LCD televisions, including high end Sony and Samsung 3D TVs, now utilize a strobed backlight or scanning backlight to reduce 3D crosstalk during shutter glasses operation.
In vision therapy of amblyopia and of intermittent central suppression , liquid crystal devices have been used for purposes of enhanced occlusion therapy. In this scenario, the amblyopic patient wears electronically programmable liquid crystal glasses or goggles for continuously for several hours during regular everyday activities. Wearing the device encourages or forces the patient to use both eyes alternatingly, similar to eye patching , but rapidly alternating in time.
The aim is to circumvent the patient's tendency to suppress the field of view of the weaker eye and to train the patient's capacity for binocular vision.
The goggles mostly feature a much slower flicker rate than the more well-known active shutter 3D glasses. From Wikipedia, the free encyclopedia.
