I know this is probably a simple issue to fix, but I have no idea how. My SONY Bravia KDL 26s2000 has one HDMI port. WHen I hook up my Nvidia GTX 260 Core 216 (Vista 64-bit SP1) the taskbar is cut off--so obviously the screen dimensions are wrong. I cannot find any obvious way to correct that. DO I jsut keep trying different resolutions? That doesn't seem right since it is the aspect ratio (116:9 for 1080p) that I need and Vista is giving me the typical 4:3 computer screen ratios. Since I ma new to HDMI from a PC, I have no idea where to look to correct this. SONY's menu claims aspect ratios can only be adjusted on the TV for the PC port which is RGB only--so that's not a HD solution.
