I recently bought a 40 inch Samsung LCD to use as a computer monitor. When I initially plugged it in, the tv had some overscan issues but I fixed that using ATI's CCC custom screen setting(set it at 1840 x 1020) the only problem is when I switch to another source and then switch back to my PC HDMI in source, it will now not recognize that there is a signal and I will have to restart my PC if I want it to show up on screen again. Now, when the LCD was being over scanned it had no problem switching between sources. So I am wondering if there is some way I can make my LCD have no overscan issues and still be able to switch back and fourth between different sources? Thanks a lot for any help you can provide.
