Browsers that support 120hz monitors

post #1 of 8
Thread Starter 
If you have a 120hz monitor, only IE10 is butter smooth at both scrollbar scrolling and mouse wheel scrolling. I prefer other browsers than IE so I hope to create some mind-share about this. cool.gif

I used a 120hz monitor and a 120fps camera to enhance the difference.

On a related note, Windows 8 is smoother than Windows 7

Unfortunately, although IE scrolls nicely, Internet Explorer does not do 120Hz web animations:
www.testufo.com

Please see:
www.testufo.com/browser.html
"Internet Explorer Does Not Support 120Hz Animations" (only scrolling)

View these pages in Chrome, FireFox 24+, Opera 15+, Internet Explorer.
You'll see Chrome/FF24+/Opera15+ animates smoothly at 120fps, but IE animates only at 60fps.

And here's my testing:



It was discovered that Internet Explorer has a built-in frame-rate cap of 105fps for HTML5 animations. This bug has already been reported to Microsoft.

IE 120Hz support is limited to scrolling, not animations. For now, use Chromium Smooth Scroller plug-in for Google Chrome, to get the smooth scrolling, while getting the benefits of 120Hz web-page animations (e.g. www.testufo.com which does not successfully animate at 120Hz in Internet Explorer)

P.S. Popular Web Animations (view in Chrome, Opera15+, or FF24+)
www.testufo.com/#test=framerates -- Demonstration of 120fps vs 60fps vs 30fps
www.testufo.com/#test=framerates-text -- Demonstration of text scrolling (120fps vs 60fps)
www.testufo.com/#test=photo -- Demonstration of motion blur during fast panning
www.testufo.com/#test=eyetracking -- Demo of motion blur caused by sample-and-hold
www.testufo.com/#test=blackframes -- Demo of flicker to reduce motion blur

Test with 60Hz, test with 120Hz, test with 144Hz, test with LightBoost turned on/off. Also test in Internet Explorer, it doesn't look correct because Internet Explorer can only animate at 60 frames per second.

Also, upcoming HTML5 3D games running inside a web browser such as www.unrealengine.com/html5 (works automatically at 120fps in FireFox 24+ on a 120Hz monitor), allowing web browser animation framerates matching refresh rate becomes important. This require compliance with a W3C standard of a Javascript function called requestAnimationFrame() to be synchronized to VSYNC. At this time, Internet Explorer does not comply fully with the W3C standard as it stops keeping the programming API requestAnimationFrame() synchronized to refresh above 105fps (exact 105Hz framecap built into IE10+)

I've posted about it in W3C, the web standardization group:
... http://lists.w3.org/Archives/Public/public-web-perf/2013Aug/0057.html

Finally, Microsoft has finally acknowledged this today as a bug in Internet Explorer:
... http://lists.w3.org/Archives/Public/public-web-perf/2013Aug/0068.html

However, it still remains "Closed As Designed" in Microsoft's bug tracking system.
... https://connect.microsoft.com/IE/feedback/(...)fails-on-120hz-computer(...)

Also, I helped FireFox to begin supporting 120Hz monitors, now a part of FF24+ Beta:

I'm sorry to bring childishness to this thread but ewww smooth scrolling sicksmiley.png

Also, do you actually have a monitor designed for 120hz? It appears you have one of the overdriven korean monitors.

I sometimes dislike 60Hz LCD smooth scrolling.
LCD motion blur during smooth scrolling makes me feel sick.
But I love CRT or LightBoost smooth scrolling!

For me, LightBoost smooth scrolling allows me to read text while scrolling a webpage, because there is no motion blur at all. Text is perfectly clear during panning motions. Regular 120Hz monitors only reduce motion blur by 50%, but using a LightBoost strobe backlight, more than 90% of motion blur is reduced; so much that text is still perfectly clear when scrolling. This is because of the strobe backlight (see high speed video, and also see PHOTOS: 60Hz vs 120Hz vs LightBoost.

But that's besides the point. Smooth scrolling is VERY useful if the text is as sharp as moving a book upwards/downwards (as John Carmack described in his YouTube). Only a few displays can do that; like a CRT display or a LightBoost display. Smooth scrolling that's as perfectly sharp as stationary. Even regular 120Hz displays still can't do that (they only have 50% less motion blur).

Indeed - if I could justify the cost I'd go out and buy an nvidia gpu and a monitor with backlight strobing.

I'd also argue that 120hz monitors reduce motion blur by far less than 50%...but of course that depends on the model, whether overdrive is being used, and the transitions the measured pixels are actually making..

Not just the monitor, but there are a lot of variables. Regular non-LightBoost TN 120Hz reduces scrolling motion blur by a full 50% *if* (A) it's perfectly synchronized to VSYNC, (B) the pixel transition times are far less than a refresh, (C) the pixel step during scrolling is exact from refresh-to-refresh (consistency). Some people are MUCH more sensitive to motion blur. Stutters, microstutters, judders, framerates lower than Hz and framerates higher than Hz, creates additional motion blur:



So some web browsers such as IE10 at least do an excellent job of smooth-scrolling because it does it synchronized to VSYNC, and at exact pixel steps at a time. Actually, when we're doing mathematical perfection, such as www.testufo.com/#test=photo in the ideal scenario (perfect frame rate match, zero stutters), you get maximum motion clarity; and it becomes easy (by human eye) to see that many 120Hz displays has almost exactly 50% less motion blur than 60Hz, in this specific test case. Since you've eliminated motion imperfections from being the weak link in motion blur.

So, VSYNC-synchronized motion at locked framerates, get the maximal improvement in motion blur, a full 50% improvement on fast-response TN monitors where pixel transition speed is a tiny fraction of a refresh (e.g. 1ms-2ms out of 8.3ms, lots of safety margin for further pixel settling), and roughly a 40% improvement on overclocked IPS 120Hz monitors (the 5ms IPS can actually be closer to ~10ms for a lot of gray-to-gray values. 10ms is longer than 1/120sec, so this creates some situations such as three overlapping refreshes when taken with a 1/1000sec camera exposure. This bumps down the theoretical achievable 50% down slightly).

Absolutely.

Motion blur is a great way to describe the cumulative consequence of various unwanted features in a display, but I try not to talk about it as a quantitative gauge.
