I’ve tried it out with Arc, but I don't have a definitive opinion yet; I need a bit more time for testing.

I recommend trying Lubuntu. But it should be noted that it lacks vsync and possibly hardware acceleration.

I'll start with the TV since it's the only true 8-bit display I have. 4K/8K videos on YouTube in Firefox play very smoothly on the 4K display (most likely, hardware acceleration for YouTube in the browser is present). While watching videos, my eyes feel relaxed, creating the sensation of looking through a window rather than at a screen. I enabled 8-bit and limited brightness range for this purpose because I'm sensitive to brightness. The text is slightly easier to read than on Ubuntu, but TV is not designed for reading from the screen.

I'll move on to the monitor (which is 6bit+FRC). I can't enable 6-bit because the default kernel dithers at 6 bits, and the monitor's FRC puts additional strain on my eyes. The fix is needed, which I implemented in the Ubuntu kernel (I will publish it along with a build guide). So, I'm still making progress here.

I'll check a bit later to see if it's possible to lower the threshold for HDMI to 6 bits in the kernel. In theory, there shouldn't be any technical obstacles.

The kernel rebuild will be required here. I plan to upload the kernel code with the fix on GitHub within this week, along with a build guide (two weeks at most; everything depends on the workload at my work).

Also which version are you using 18.04 or the latest?

I am using the latest version.

WhisperingWind With Stillcolor enabled. (i.e. no dithering) Just some applications that mostly use system UI components like System Settings, Finder, also a screenshot of any browser displaying this thread in this forum (as I'm familliar with the UI of this site and will be able to detect if there's any anomalies in the colors). Use light mode

(If I can't find anything in the first general UI screenshots you take, then I can put together some more specific test patterns that I can send you)

But first I just want to see some basic app UI but as a PNG frame capture taken through the lossless capture card

For each example, send me both a direct PNG frame taken from the lossless capture card in addition to a "standard" PNG screenshot taken through normal methods, so I can compare what's "supposed" to show vs. what's actually being output in the HDMI video signal.

I run a chrome://gpu

This is what i've got:

Only software rendering. which is good.

moonpie I know. I optimize for the system with the least eye-strain.

And this is a desktop, so it's easier, because power isn't an issue.

Windows 11

On the ARC A770, I was only able to enable 6-bit in Windows 11 when ACM was turned on, which unfortunately is not usable.

Lubuntu and my monitor

I ran Lubuntu in 6 bits without dithering and noticed that the white background has a slightly golden tint, which leads to a bit of disorientation (but much less than with dithering enabled) when reading from the screen. I'll try to change the monitor, but I'll be able to do that sometime in December.

WhisperingWind it could be because of text anti-aliasing. Maybe. They sometimes do weird tricks to make the anti aliasing look good.

Its possible to test this by disabling anti-aliasing in the browser(modern browsers do their own anti-aliasing, not the OS). Personally i also play with the zoom until the letters look good.

This is something related to color profiles or the monitor, as recording a white background through the HDMI recorder and analyzing it with a colorimeter showed that it true white. Here is the part of the image: https://ibb.co/5RxRbSD

Thank you, I will try changing the fonts and smoothing

WhisperingWind What happens when using 8 bit you fill the screen with the color (11111100, 11111100, 11111100)?
