Pretty much the same spec as the 1080, 1084(s) and other 15khz RGB monitors. That is to say it's not designed to handle Super hi-res modes without flickering.
Specs for 1080's and 1084's are on the BBOAH...
Spot on.
Highest you can run without getting mad flickering is going to be either NTSC or PAL High Res just like the 1080 and 1084. I owned one back in the early 90's and its all but identical to the 1080 and 1084.
