Re: Do all TN G-sync monitors have banding issues? Help me p
The banding at dark levels can be attributed to the sRGB transfer function. It approximates a 2.2 gamma curve, but RGB levels below 11 are linear, thus they leave black very quickly. Not all monitors follow this function. AdobeRGB is 2.2 throughout, and this makes the very dark levels indistinguisha...

Re: New TestUFO "Exact" Refresh Rate Test! (e.g. "119.99716
This is exactly what I needed! These variable refresh rates have been an enigma to me for long, and this will surely help me get a better understanding of the underlying mechanics. I am especially intrigued by toggling between 59hz and 60hz, which as expected, yield ~59.94 FPS and ~60 FPS respective...

[TestUFO Aliasing Visibility] Anti-aliasing gamma correction
One thing I have noticed is that a visual pattern emerges from the line when anti-aliased. I suspect that this is due to a lack of gamma correction. Having the option to toggle this would be useful.

Re: What exactly causes V-sync to introduce input lag?
The pre-render buffers are filled with data that depends on old input. Although you can set the buffer size to 1; the setting is called "pre-rendered frames" on Nvidia and "flip queue size" on AMD. It's not uncommon to see something like 100ms total input lag in some cases because of this. Ah, I wa...

Re: What exactly causes V-sync to introduce input lag?
When the game submits the frame for output, it keeps working on new frames. It doesn't actually wait for the vblank itself. The OS/driver is doing the waiting for vblank, but the game doesn't actually care. The game can submit another frame later on, even though the previous one is still waiting fo...

What exactly causes V-sync to introduce input lag?
NOTE: Some useful low-lag VSYNC ON code programming techniques is in Page 3 of this thread. I did a test on a G-sync monitor by recording the screen at high speed while moving the cursor around. I can conclude that in my case, G-sync right below the refresh rate has a 3D application that uses the W...

Re: Motion test videos
I would if I could, but I honestly have no idea how to make a perfect rendition. All I could do is capture, but that is a messy process.

Motion test videos
Are there any good motion tests in video format so one can view the exact same patterns on multiple displays and playback devices? The TestUFO tests are already very good, but they are of course limited to HTML. I would love to have them in a collection of MP4s.

Re: Display timings
I only know one good software to see EDID data: http://www.entechtaiwan.com/util/moninfo.shtm Try it. Looking at this, it reports my current mode as being 120.4Hz, but I can't make sense of why this is. If I multiply the pixel clock and blanking resolution as reported by the program, I get a freque...
