My setup: Biostar TA790GX A2+ w/ on board HD 3300 connected to a Samsung HL-R5087W (older 50" DLP) via HDMI. Driver version 8.9. The TV supports 720p/1080i, no 1080p. My screen size is set to 1280x720 via the control center. The TV reports that it's receiving a 720p signal (found out what the info button does). I also had the black borders.
Ran the aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0 command. That fixed the black borders, but I lost part of the screen (overscan I assume by reading all these other posts).
The TV supports different aspect ratios, zoom 1, zoom 2, panoramic, normal, 16:9, 4:3. However, when it detects an HD signal it only allows to select 16:9 or 4:3. I dug through all the menus, and couldn't find anything else to change the overscan.
So, I ended up using the following settings to get the screen sized right.
aticonfig --set-dispattrib=tmds2i,positionX:47
aticonfig --set-dispattrib=tmds2i,positionY:18
aticonfig --set-dispattrib=tmds2i,sizeX:1195
aticonfig --set-dispattrib=tmds2i,sizeY:679
I'm happy with this, and the wife comes back from a 2 week trip tonight so I need to be done messing with the production box. I just thought that I'd post my results in case anyone else is having problems with a Samsung DLP.
By the way, in Myth I had set the resolution to 1279x720 to get a usable display.
