[QUOTE="Owlsroost, post: 414161, member: 83973"] 1. There isn't really any difference electrically - DVI & HDMI use the same signals, just on different connectors. HDMI can have embedded audio (but it's carried on the same wires as the video) and it supports other colour spaces - e.g. YCrCb - as well as the RGB that DVI uses. This is why a simple passive DVI - HDMI adaptor/cable is possible. What happens is that the PC reads the 'EDID' information from the TV and works out from this what resolutions and refresh rates the TV can support. It combines this with what the PC video hardware can support, and the possible resolutions are offered as choices in the Display Properties control panel. 2. As above, this depends on what is supported by both ends of the HDMI link.... What display choices is the Display Properties control panel or ATi CCC offering ? Also, a quote from the Lenovo T43 support pages : "* Support for a DVI monitor is through the ThinkPad Dock II option and is limited to a resolution of 1280 x 1024 at 60 Hz." ....so you are probably out of luck with getting 1360x768 on DVI Tony [/QUOTE]
