I have a Samsung HLM50W DLP TV. When I hook a laptop to it running Win XP, the only resolution that Windows will allow through the VGA monitor connector is 800x600, which is what the TV manual shows is the supported "SVGA" resolution. The TV manual says it can support higher resolutions at XGA, the instructions for using the TV as a monitor call for setting the screen resolution in Windows to 1024x768, and the laptop (a new, widescreen Compaq with an nVidia GEForce 440 card) is capable of higher resolutions on its own screen, but I don't know how to access those resolutions. The 800x600 limit applies whether the PC is dispalying on both its own monitor or only on the TV monitor. When it is displaying only on its own monitor, a full range of resolutions is available.
Any idea on how I enable the 1024x768 setting for the external monitor? (I can find no drivers at Samsung.)
