I have been using 1600x1200 for 20 years. I had a single CRT. Later upgraded to two LCDs of the same res.(So I guess 3200x1200, but not for gaming.)

Then 1920x1080 didn't seem worth the cost.

Then gaming landscape changed and 60Hz is not a thing anymore, now it has to be 120+.

So have been waiting until 4k 120Hz+ and the money in my pocket meet.
