The most recent firmware to the LG 27GN950-B pushes the display rate to 160Hz at 4k (the firmware takes a nervous 30+ minutes to load)
A very nice monitor, well-suited to DisplayPort, DSC and the new graphics cards coming out (I was lucky to bag an RTX3070)
Honestly, if this had an HDMI 2.1 it would have been an instant buy for me running this well. Maybe a refresh next year will have it. Got a series X as video card prices in Canada are insane right now if available and consoles are almost readily available and are cheaper than US pricing after conversion.
