JTL yeah, sourcing the actual Intel card variants is hard in this case - they only made them for the initial series (770/750) and while a 750 can still be had (for ~$200) the 770 is all back stock or used and will run double that amount easily. The 580 never had a reference board, and it's not clear the 380 did either, so I was curious what brand 380 eDenon-2 had since that VBIOS would most likely be "safe".

He says it's Gunnir, which is unfortunately an APAC-exclusive brand. My options to get it in the USA are limited. So I'm going to grab an Intel reference board 750 and keep my fingers crossed. It'll run me $239 from Amazon, which is a bit of a premium, but worth it if I can use it for a few years without pain. I could grab one locally for $200 (for an unopened box model) or even less on the secondhand market. But at Amazon I can return it...

      Gurm Actually from the several graphics cards I have tested, besides NVIDIA, they dont support Linux, the Intel A380 and AMD RX6400 have the same color, and both eyestrain free. So AMD is also safe. From the several monitors I have tested, I find HVA panel is more eye protected than FAST-IPS, this is very important. And I tested them all via DP cable.

          This TN display is eyestrain free, the only disadvantage is bad viewing angle, you can only sit straight in front of it.

            Can you add panels used in your eye-free monitors? Using engineer menu

            This TN monitor is good so far, you can buy this. Here I switched from Arch to Debian, the result is same.

            eDenon-2 changed the title to [monitor] some monitors testing & experience .
