My "vintage" desktop runs 3 x 27" 1080p displays (5760 x 1080), while my legacy MSI GT70 (13 year old) gaming laptop has a 17" 1080p display, and is still running strong.
My 6 year old Intel based MacBook Pro 16 runs @ 3072 x 1920.
Finally, my current gaming laptop (Lenovo Legion Pro 7i) has a mobile RTX 4090 and a 16″ WQXGA (2560 x 1600), 16:10 aspect ratio, 240Hz variable refresh rate display.
I've been eyeballing the 49" Samsung Odyssey G9 which runs @ 5,120 x 1,440, for use with the Legion Pro 7i.
This morning I received notification that my Bigscreen VR Beyond 2e universal fit headset I pre-ordered back in March ships out today. It runs dual OLED 2560 x 2560 displays.
