every each which is diamondtron they are completly flat and can easly mantain 120hz on higher resolutions ofc depends on model ; p but most of them do 120hz on 1024x768 resolution.
I had a P992 trinitron that did 120Hz at 1024x768, but I found that 100Hz was easier to play with than 120Hz for some reason. Too bad it has some problems with its capacitors so everything got bright and washed out.
