Variable Stretch

I was playing around with Powerstrip last night trying to 'brute force' some of my more stubborn 4:3 games to work a little better on my 16:9 projector.

And I came up with this...

You can set up a custom stretch on a resolution that you use for gaming and make it 'stick' for some titles, namely games that don't switch screen res when they are running. This is nice because you can get away with a certain amount of stretch before the image just starts looking too deformed rather than just having to go straight to a 16:9 deform of your 4:3 image.

I did this last night for MicroSoft Rallisport Challenge.

Chose my 1280x1024 resolution as it already maps well vertically with my Projector seeing the signal as a 1080 source. Went into powertstrip and clicked on custom timings and chose 'lock scan frequencies'. Next just stretch the image out horizontally to get the most width you can without deforming the image too much (or all the way to 16:9 if you don't care), click apply and then save the setting with the name "1280x1024 stretched". Finally make an application profile in Powerstrip for your chosen game and make sure to check the box that says to activate the profile at game launch. Choose the "1280x1024 Stretched" that you just made in the dropdown box for the resolution and click save.

If you've done everything right then when you launch your game Powerstrip will kick in with those custom timings and apply your chosen resolution and stretch.

Like I said this only works for some games, Rallisport Challenge is a good example, games that switch resolution after startup wont work with this as they just call system default timings for the available resolutions rather than your custom ones (still trying to get around that one).

I don't know if this is any help to anyone, or if it's old news, I just discovered it last night and wanted to contribute something to the community.

Hope it helps someone.
