Not meaning to hijack the thread.

But speaking of backlight uniformity - is there any known way to replace edge backlighting with a direct one? I know it involves a lot of work, icluding prism replacement and maybe installing a new LED driver. Could there be any pre-made kits? Is there any monitor modding forum threads or other resources?

I've recently been trying to improve backlight uniformity on my monitor (MG279Q) via experimenting on metal frame pressure points, and the results were quite weak with a lot of time investment.

You could make your own monitor modifications or even whole monitor but the costs are insane and you need to get "prototyping" boards that you can program. There is that 4k modding site that sells kits for 4k120, 1080p480. Haven't seen backlight kits offered by anyone. You want to replace edge lit with FALD... well good luck getting the diffusion plastic layer anywhere other than from other FALD panels. Plus the complexity of controlling FALD well, unless you want a useless whole screen ON/OFF FALD which would be a royal waste of everything.

killuchen: post pictures of your received monitor. You can get some reasonable low BLB with the revision Acer uses but glow is always present, sometimes more sometimes less.
Unless you're getting this at low price it doesn't really make sense to bother with M270DAN2.x.

There is XV272U, VG271U now and 27GL850G to arrive (who knows when, Q2?), maybe more but I haven't seen anything, hard to navigate what is new at CES.

I'll post some pictures later today when I have time. It's the Acer XB271HU model. I love it so far. The BLB doesn't look bad at all tbh in person. I traded my Benq xl2540 for this monitor. I love the 2k ips panel.

In practical usage, on an IPS, I find that BLB and glow sort of blend together since BLB tends to happen in the corners where you see IPS glow anyways.
