Your probably right, it's an old TN panel in a 10yr old laptop... I'm gona have to steal someones shiny modern IPS in a minute :P (I know they are generally slower response but it's 10 years newer so you never know) [edit] No IPS still super slow. How common are >60Hz computer displays these days?

Common for gamers, relatively unknown for everyone else. They typically go up to 144Hz.

There are newer ones that do 240hz, but they are TN.

If you want to have some fun, try testing your reaction time at https://www.humanbenchmark.com/tests/reactiontime.

It's not quite a keyboard delay test but more of a general human reaction time test.

The best I can do is 160ms after 5 tries on a 2560x1440 60hz IPS panel.
