While I've had an HTPC for some time I've never tried fiddling with changing the refresh rate from the 60hz default, using Powerstrip solely for setting resolution. I thought I'd try seeing if I could get 50Hz for PAL .. well I can, sort of. I have an ATI R9700 using Catalyst 4.10 driving a Sharp Z200E via DVI, this gives me 60Hz only according to the Display Properties. I use AnyDVD to handle multi-regioning and it comes with a feature that can run a utility to set the refresh rate based on the type of DVD inserted, ie. NTSC or PAL. However, when I try to run this for any value other than 60Hz it displays a dialog saying it couldn't set the frequency I want, eg. 50. I installed Powerstrip and find that it CAN be used to set 50Hz, a fact confirmed by Reclock .. I'm not using Reclock at all at the moment, I just ran it to get the true value of the refresh as Display Properties lies and still says 60. So, PStrip can set 50 but not AnyDVD's utility. Okay I though, I'd set up 2 PStrip configs and toggle between them, a bit of a pain when mixing NTSC and PAL DVDs but I'm sure I can automate it given time. Sadly this is not to be, PStrip can't seem to store more than one setting per resolution. So I'm stuck, I can manually dial 50 or 60 into PStrip and it'll set it but that's more than a little tedious, but I see no other way of doing it. Am I doomed to being forced to use 60Hz all the time if I want to use DVI? I haven't tested it but I assume if I switched to VGA then I wouldn't be locked into 60Hz by Windows.
