Hello, My ATI card found it necessary to underscan my display (Plasma TV) and I can't find a way to reverse it.
I've tried several versions of Catalyst drivers; none of which allow me to underscan/overscan my display. Nor do they allow me to ignore the EDID. I know ATI CCC has these features but they are missing and I can't figure out why. On my Samsung 2032GW monitor; ATI CCC had those features readily available. Same with a Samsung 46" series-5 LCD I tested it on. For some reason, it is not available for this display.
In ATI CCC, the DTV option IS MISSING. Does this mean the card does not detect the HDMI? If I remember correctly, the DTV option has the scaling sliders; one that allows you to underscan/overscan.
The Panasonic TCP42G15 is a 2009-model G-series plasma TV; 1080p capable. I am using a Windows PC running Windows 7 Home Premium, Catalyst 9.10 drivers on an Asus Radeon HD 4870 1GB.
The PC is connected to the TV via HDMI (through a DVI-HDMI adapter). Audio and video works fine. Other resolutions that I tried did not remove the black border.
I tried a different HDMI port and various picture control settings and nothing has worked. Used the PS3 on the same port with zero scaling issues. The underscan is between 6-8%.
It appears the GPU is initiating it (not 100% certain) since the TV has no picture control options that allow me to remove the underscan. There is a black border around the Windows desktop approximately 3/4" horizontally and 1" vertically.
I'm considering purchasing an NVIDIA card to see if it makes a difference.
Any help is MUCH appreciated. - Chris
