[QUOTE="htpcoz, post: 20913, member: 13987"] So near, but yet so far :cry: With a little more investigation, (using vnc temporarily to try to work out what is going on when the sync is lost) I'm finding that when I set the component output to 1080i, if I have a look in the custom resolutions screen (of the driver properties, as well as powerstrip) I can see that 1080i is running at 30Hz, rather than the expected PAL 25Hz. It seems that 576 based resolutions are expected to be at 50Hz by the drivers. Whereas, the standard 1080i resolution provided by the driver is only outputting in 30hz, of course it does, doesn't everyone live in the US! :roll: I've tried the various other standard resolutions provided in the drop down list, none of which sync to my screen. I've tried configuring the custom resolution manually, based on the timing settings from my previously working powerstrip timings, however from what I can see it looks like the units of measurement between the powerstrip custom res and nvidia custom res screens are different. I'm trying to work out how to map between the two measurements and then hopefully shoud have 1080i 25Hz (in theory), by entering the correct timings in the Nvidia pages. This is complicated by two other problems. 1) Whenever I apply a custom resolution in the Nvidia property pages something in the driver goes crazy and chews up most of the CPU on the machine until I reboot. 2) Also my old friend powerstrip just doesn't seem to like talking to the Nvidia drivers. Where the Radeon card would obey exactly what powerstrip requested, the Nvidia drivers force me into virtual desktops. So it is all but useless. [/QUOTE]
