*Overscan for TV-out is hidden in the drivers still, no way to enable it without a tweaker or registry edit.
*How do you enable 1080i output?
* I scanned the registry, overscan appeared to be enabled in the current control set, but maybe I missed an entry. Rage3D tweak enabled it no problem, I was able to use the new force TV display to check that the button appeared on the advanced TV display properties since I don't use anlog NTSC output anymore.
* Not so easy this one. In order to enable High resolution interlaced display from the VGA port, I had to connect the component output gang adaptor (YPbPr) and enable 480p, 540p, 1080i<--probably only needed this one, these are the resolutions supported by my widescreen display) and 16:9 and then reboot. I could now pick 30Hz interlaced for 1920x1080 (VGA out not YPbPr is what I'm after)....but the timings were off. This could totally be from a conflict from powerstrip as I use it to tweak my output resolutions using Karnis's guide at AVSforum <--Highly recommend for ATI cards). I uninstalled powerstrip, downloaded the new 3.43 build 402 version, created a custom timing for 1080i <--the ATI one had worked for me since Cat 3.4 btw) rebooted, and my 1080i is working perfectly again...whew! Threw Shrek on to check a few chapters out....absolutely gorgeous.
I'm not sure why property sheets like the rotation tab and options like overscan and enable HDTV modes aren't exposed in the drivers, as the registry keys are there, and have been there for a long time now. Rage3D tweak works great, but combined with powerstrip and ATI's control panel makes for a lot of opportunities to create conflicts<--which I think may have happened) Uninstalling powerstrip to begin with may have saved me some grief, I'm going to re-install later to see if I can duplicate my problems. IT IS WORTH the hassle though, 1080i DVD output using the Radeon's excellent video scaling, output to a large widescreen display is a sight to behold.
