Hi all, I thought I would post my findings on getting this little projector to playback HD material smoothly from the PC - it does it! I got native 48Hz refresh to work using the custom display timings section within the Nvidia Control Panel (Forceware driver release 169.21). I hope this info is useful, as those of us familiar with the almighty powerstrip will no doubt have discovered that it doesnt work with the latest generation of nvidia cards, apparently due to nv witholding vital specs/info on how their new cards work
Anyways, at least they have still given us the ability to configure custom timings, albeit with much more trial and error...
I know the H30 is an antique these days, but I still love mine and will keep it as long as possible as im still very happy with the output and the scaler is still a beauty imho...
As well as the 48Hz mode, ive also posted the timings for 50Hz mode just for the sake of it, for those of us who want perfect PAL DVD playback. Here you go! :
One final note of advice - the Nvidia custom display timing section can be picky. I have found that when you first create the new custom timing using the info in the above images, that you need to click OK, then choose the newly saved/created display mode from the list, click "Edit..." then go down to the bottom and change the scaling type to "Display (None)" then hit test, and then OK to save.
You will notice that the 48Hz mode uses the H30s internal scaling/resolution mode of 720x576/48Hz, I got timings for 800x600/48Hz but the pj still uses the 720x576 mode, and the scaling doesnt look as good. I couldnt get native 1:1 800x600 48Hz mode even after much trial and error, maybe someone else can figure that one out
Anyhow, go enjoy some silky smooth HD playback on your H30 now! Enjoy!
