Planning to dual-boot with Windows either Debian or Mint on my OLED laptop. Are the tools that I have on Windows really useful? (pixel refresh, pixel shifting)
Pixel Shift and Pixel Refresh are monitor hardware features, not managed by the OS.
Well it’s usually In the firmware. As this is a laptop, the display is usually a dumb display. It depends if the manufacturer wrote the firmware into a controller or used windows drivers.
Its an ASUS laptop. The tools are MyAsus app.

HDR is probably something you want to use with an OLED and quick search of current status of HDR on Linux shows it’s only on KDE Plasma 6 on Wayland… which might be in beta this year. Proton has a beta for vulkan games for AMD GPUs.
For me the HDR issue is still a dealbreaker for recreational use of Linux.
Off topic, but why do you want hdr on OLED?
Because your content’s color and light intensity data, and the monitor’s ability to turn off individual pixels when they’re not needed, are not the same thing. If anything, these two go best together
Do OLED panels typically have more than 8 bit per color brightness levels? I always thought hdr was more of a preprocessing step to prevent clipping unrelated to display tech.
HDR means High Dynamic Range. The range of values on an SDR display (Standard Dynamic Range) is 16-235 but the range of values on an HDR display is 0-255, that means that the color “black” on an HDR display is actually black and not “dark-gray”.
This is dumbed-down because I don’t know the more technical stuff.
Also it has nothing to do to “color saturation” (wrongly called “vividness”). That’s a dumb marketing thing since you can do the same using every display in this world.

That’s tone mapping, HDR is actually having more than 8 bits and often also more colorful colours than normal. I think 10 bits are common.
I don’t really care about HDR. So I guess I’ll dual boot with Mint after I do a fresh install of Windows.
HDR works in gamescope (and mpv) right now when started from a TTY.
It’s not ideal but since so few games I play support HDR it is enough for me until Plasma 6 comes out.
I bought an oled monitor, and returned it.
- HDR is not enabled in mainstream kernel, and requires to hack and compile a custom kernel (6.2)
- Even if you compile the kernel, the session you might be using doesn’t support it. I think only a gamescope session does.
- If HDR is not your concern, the know that OLED monitors don’t work with 3 pixels, but more in different configurations. LG are WOLED (RWBG, 4 in a non standard distribution), while Samsung uses a triangle!. What this means is that fonts will be displayed awfully because they’re programmed to be displayed in RGB configurations.
- LG presents artifacts on the left and right side of the fonts because of RWBG config.
- Samsung presents artifacts on top and bottom because of the triangle.
- This happens both in windows and Linux. Something to do with freetype.
So yeah, I think no platform is ready for oled monitors just yet (maybe macOS?). I switched to a cheaper LED gaming monitor.
Im thinking QLED. Really all I care about is nicer colors. I dont have any complaints about my current OLED laptop display other than having to worry about burn-in.
