More than 10 years after the IBM T220/T221 came out, but the IBM monitor still has a significantly bigger resolution (3840x2400) and PPI (203.98 vs 139.56).
Yes but the problem is its low refresh rate. If you're looking at static images, I'm sure it will do great, but if you are trying to watch a movie, play a game, or do anything that has fast motion, you won't have a good time.
Gotta assume the monitor supports 60, going to 30 would be terrible.
8ms, according to the OP.
8ms is the panel switch rate, not the same as the slow refresh rate of the Lenovo due to the bottleneck in the interconnect with the GPU (4 DVI-channels and 41 Hz refresh, when the panel surly did 60 Hz). It is a massive datarate, especially for a 12 year old system.
60 fps, but the current drivers for both AMD and Nvidia (still in development) make you connect 2 cables and essentially treat it like 2 1920x2160 displays from what I read.
