Need custom screen resolution help (ATI)

[Temi_D]

Hi all
I have an HD4870 with catalyst installed. I need to set a custom resolution of 1920x540. The minimum height that the catalyst will let me set is 1920x720. Someone told me to try powerstrip but it doesnt save the resolution I set it to. As in I want to add the res profile so that I can select it anytime like the one with catalyst below:

im sure i done this to help with my mates rez i think i just used CCC and it let me set it and saved it... but if i Killed the CCC.exe it would revert, i was using 9.1 i think.. they may have changed it tho because of issues with certian gfx cards
