Good to know. Looks like a good display but knowing more now I definitely don’t want one. What’s the max refresh rate these little screens can handle? Not counting limitations of the Arduino unit. I’m also looking into the raspberry pi 4 to replace my old junk windows tablet that has been my only PC for 2 years and would like to have live temp and CPU load info on a separate screen refreshing as fast as possible. I’m not expecting movie frame rates but 5-10 FPS would be nice and I know the quad core CPU on the raspberry pi wouldn’t even notice. With how fast computers are now I don’t like seeing half second or longer delays between screen updates. Just seems low tech to me. Even my $5 eBay multimeter updates 5 times per second.
