I don't even know if this is adjustable, in the monitor menu and windows it only shows me max 240... but that wasn't the reason I bought it, it was the 10bit colour depth and that is only supported up to 144hz and only 8bit at 240Hz. I compared for a long time, Oleds are too expensive for me (double) and this was in my opinion the best monitor that is now available with HDR -> the Gigabyte M27Q has more sRGB, but then also less contrast ratio ... more questions than answers, but it's a great monitor! I'm mega satisfied ))

Should eig work hane a rtx 4080 and kommr da locker suf 260HZ on the monitor that you can then overclock in the menu at the screen.

As far as I know that should work. If you want to save extra money, I would recommend MSI G274QPXDE.

I can't answer because it was a gift.
