> pixels the size of my hand

Sometimes this is refreshing. (display joke there, heh)

this is a big monitor.

Many UIs don't scale particularly well with very high resolution. So you get UI elements with super-fine text or icons.

Some linux console fonts are almost unreadable with just 4k, though recent releases seem to be addressing this.

also old games.

for comparison, I think this is basically the dell 43" monitor with pixels on each side (16:9 -> 21:9)

the height of the panel is similar, the width is higher (plus curvature)
