Console games and HTPC. The SteamBox can support G-SYNC, as various other upcoming consoles that can use nVidia. Also, many people use TV's with Home Theater PC's, for PC gaming on the big screen. The forum section on AVSFORUM.com has something like a million members, it contains the world's...

Actually, G-Sync improves all variable framerate situations, regardless of Hz. Marketing this is another question altogether, but the benefits are indisputable, even in the 30-60fps @ 60Hz range. See How Does G-SYNC Fix Stutters? -- it's applicable even to lower framerates and refresh...

G-Sync is unrelated to strobing. BENQ will come out with PWM-free G-Sync monitors. (not sure regarding ASUS VG248QE's G-SYNC upgrade) There's a strobe feature, but it's optional. -- The strobe on LightBoost is squarewave, while the strobe on a CRT is a softer decline (phosphor decay). -- Also...

True, high speed video helps. Not yet fully representative of what is actually seen by human eyes in person; but it demos better than non-highspeed video. Still far more dramatic looking in person. But yes, if you must show off video of G-SYNC, you need high speed video (if using...

Both hardware and software are cooperating. For example, the frame is pushed to the monitor immediately the moment Direct3D Present() API is called. Basically, the existing Direct3D software API is now triggering the delivery of the frame to the monitor if the monitor is currently waiting...

Then you've got a heightened sensitivity to 60fps@60Hz edge-strobing issues (similiar to 30fps@60Hz). Some people see the edge strobing, others see motion blur. But that's not perceived as erratic/random stutter. Still, 60fps@60Hz always will be smoother than 55fps@60Hz or 65fps@60Hz...

Try again with VSYNC ON, or comparing to www.testufo.com Motion fluidity G-Sync -- is similar looking to VSYNC ON Framerate=Hz -- it doesn't look like VSYNC OFF Framerate=Hz What's diffrent is that G-Sync can maintain the "VSYNC ON Framerate=Hz" look-and-feel at all framerates.

I am personally far less bothered by this, than I am bothered by LCD motion blur. LightBoost, all the way. (or G-Sync monitor's confirmed strobe mode)

Let's carefully define terminology. When I said "stutter", I mean erratic-looking motion (e.g. the kind you see during 47fps@60Hz, 35fps@60Hz, etc) Basically, everything will look like framerate=Hz at all times. G-Sync looks like 30fps@30fps whenever the GPU runs at 30fps. G-Sync looks...

Nope. You can only have one or the other (currently). John Carmack (@ID_AA_Carmack) tweeted: “@GuerillaDawg the didn’t talk about it, but this includes an improved lightboost driver, but it is currently a choice — gsync or flashed.” See this post: CONFIRMED: nVidia...

I'd personally hope that all 4K G-Sync monitors have a strobe mode, or nVidia is breaking their promise: nVidia: “We have a superior, low-persistence mode that should outperform that unofficial [LightBoost] implementation, and importantly, it will be available on every G-SYNC monitor...

Yes, you are right. But that's simply all software design now, now that G-Sync has made it possible for game software to do so. Proper 3D game rendering would ensure that timing of object positions (in virtual gametime) correspond with the actual real-world-time of the display of the object...

To be very clear, there is a very minor side effect of variable frame rates on a variable-refresh monitor: Variable motion blur. - As framerates go down, your eyes perceive more motion blur. - As framerates go up, your eyes perceive less motion blur. This effect is self-explanatory in the...

I have added a new prominent G-Sync section to the Blur Busters website. It's going to be rapidly expanding in 2014.

Fixed-Framerate Video is INVALID proof. It's impossible to see the difference in the video because the video converts the variable framerate into a fixed framerate. This re-slots the correctly timed frames into incorrectly timed frames. The video is LOSING timing information. I can confirm...

If there's a pause for a full fraction of a second (e.g. 1/5th second freeze), you WILL see it even with nVidia G-Sync. But if you're smoothly fluctuating 30fps through 144fps, all you see is motion blur smoothly increasing/decreasing.

Actually it's remarkable; fluidity still occurs. That's because the positions of moving objects in the frame is in the correct position along the motion vector axis. Put a ruler along the display. A constant speed moving object. Refresh the screen randomly at random intervals, but paint the...

That's a definite dead giveway for variable-rate strobing. The question is; will it flicker during strobe rate changes? Or did nVidia already come up with an algorithm that prevents noticeable flicker during variable-rate strobing? If so, then I'd love to know -- and I can give them due...

A number of users of the XL2420TE has mentioned it has better colors than both XL2420T and VG248QE. It is an interesting question in how they compare to previous panels, but I thought I'd mention relative differences between current 24" panels, too. Options in triple-digit-Hz-world is...

I've solved the flicker problem of combining G-Sync with LightBoost. See my previous post. Example: 10fps@10Hz — PWM-free backlight 30fps@30Hz — PWM-free backlight 45fps@45Hz — PWM-free backlight 60fps@60Hz — Minor backlight brightness undulations (bright / dim / bright...

Eureka: I've Invented a method of variable-rate strobing without flicker at lower framerates!!! (This now makes it feasible to combine LightBoost and G-Sync without side effects) Depends. Variable framerates; use G-Sync Constant 120fps@120Hz: use LightBoost. G-Sync is still limited by...

Months ago, I created a paper, Electronics Hacking: Creating a Strobe Backlight, from my old Arduino scanning backlight experiments before LightBoost became popular. (I also used to work in home theater equipment manufacturing, and am very familiar with how LCD displays works, and understand...

I have quickly invented a new idea of combining PWM-free with LightBoost, while having G-Sync: New Section Added to "Electronics Hacking: Creating a Strobe Backlight" To the best of my knowledge, no patents exist on this, and not even John Carmack appears to have mentioned this in his twitch.tv...

As much as I hate motion blur, I prefer viewing 1:1 from an LCD, than viewing 1:1 from a plasma or closer. Sitting a mere three to four feet from a 50" television mounted at the rear of a deep desk, for example. Here, plasma motion artifacts are so unnatural looking, that even plain LCD...

Same for LightBoost. G-Sync has less input lag than LightBoost, as LightBoost has a slight additional pixel-transition-complete waiting time added at the end. Plus, in the future, frame transmission times and scan times will go up (e.g. tomorrow's 240Hz and 480Hz LCD's later this decade, look at...

Correct, frame transmission time of G-Sync is limited by whatever the current dotclock is. The dotclock used with G-Sync is currently 144Hz (the current G-Sync maximum framerate), so you've got frame transmission times of 6.9ms, but tomorrow's G-Sync monitors will probably have frame...

Photographs from the liveblog are very self explanatory for the technologically-minded (Blur Busters Squad fully understands -- as does display engineers, and people with good understanding of displays) Variable Refresh Rate Monitors (e.g. G-Sync) allow synchronizing the variable...

This is an amazing MONITOR technology that nVidia just invented -- nVidia G-Sync is a variable-refresh-rate monitor technology, that allows the monitor to immediately display frames "on-the-fly" from the GPU. Refreshing of the screen is no longer at discrete intervals! The refresh rate is no...

Agreed - especially in space movies. (Though for gaming -- black levels are far, far, far less annoying than motion blur for me) Agreed -- except for Game Mode motion uniformity. Agreed. Not for computer use at 1:1 viewing distances. Not in Game Mode with plasma processing turned off...

Yeah -- the faint crosstalk ghost effect that also happens on several LightBoost displays. Basically, a trailing ghost sharp image (non-blurred) roughly similiar to intensity of 3D crosstalk. I already explain this in the HDTVTest posting about Sony's Motionflow Impulse, and explain exactly...

Correct Neilo -- scientifically, MCFI-free methods of eliminating motion blur, tends to add more visible flicker. Generally, for MCFI-free operation, motion blur reduction is unfortunately proportional to amount of visible flicker. (and even flicker only seen under highspeed camera)...

Blur Busters Master Listing of Known Ultra High Efficency Strobe Backlights Confirmed 100% MCFI-free low-latency (adds under 1 frame) method of breaking the "300 lines of motion resolution" barrier on LCD's. 1. nVidia LightBoost -- www.blurbusters.com/lightboost/howto 2. Samsung "3D Mode" --...

Sony Motionflow Impulse does not use MCFI. It's 100% pure strobe based on the KDL55W905A, adds less than one additional frame of input lag, and is available in Game Mode! It returns over 1000 lines of motion resolution on the motion tests pattern on the KDL55W905A. Pure strobe backlights...

Cool, I didn't realize that. I've talked to David Mackenzie, Vincent Teoh and and Moderator FoxHounder., who are all fans of Blur Busters now (sent a few PM's), plus a few posts. Here's one of my articles that I posted about my tests of Sony Motionflow Impulse on HDTV Test Forums...

Actually I'm already familiar with it :-) Correct. That's how I created www.testufo.com/eyetracking It's proof that speed of LCD GtG pixel transitions aren't the limiting factor on modern LCD panels, but the sample-and-hold effect. Modern LCD's have GtG transitions that are a tiny fraction of a...

That's television view distance. Not suitable for some of us. Common proportional view distance is approximately 1:1 for a primary computer monitor. 24" monitor = common desktop view distance of ~24" (e.g. 24" monitors) 50" monitor = common desktop view distance of ~50" (e.g. HDTV mounted on...

Do you use the latest nVidia drivers? And having problems with surround LightBoost? If so, post here in nVidia's own forum to let them know they need to fix things!

Correction: LightBoost doesn't use registry hacks anymore. It's now an easy keypress to turn ON/OFF LightBoost with modern LightBoost utilities such as ToastyX Strobelight. Also, strobed backlights are becoming more of an advertised motion-blur-eliminator feature of displays. So it's easy to...

Once mass-manufacture of 4K begins at all size levels, I think 4K will be cheaper than designer resolutions (laptop size, monitor size, etc). Much like how 1080p is now cheap. Probably Apple would release a "Retina Thunderbolt Display" within a year, since it'll soon be one of the last...

Mental conditioning definitely helps, but it not alway solvable, especially if he's already a senior... You can't always make all blind people seeing. You can't always make all deaf people hearing. You can't always make colorblind people see color. Likewise, some people are unavoidably affected...
