Is it safe to use monitor at its maximum supported resolution or keep it lower than it? Does using it at maximum limit do any harm to hardware? Using max limit put stress on graphic adapter, yes or no? And does constant resolution changes, like when normal use it is some value and during playing games it has some other value cause any problem. Right now I am using Samsung 793s at 1152 X 864 at 32-bit with refresh rate at optimal on Geforce 5200 128mb. The maximum resolution supported is 1280 X 1024. But while playing doom 3 and hl2 it is 640 X 480 and 1024 X 768 respectively.
