I know someone who has a laptop and wants it to output video to a TV. I bought a cheap cable to connect its VGA output to one of the TV's composite video inputs.
The seller of the cable clearly said that the laptop must support TV-out via the VGA socket, but I assumed this would be true. This assumption may not be correct.
- GPU: NVIDIA® GeForce® 9300M GS
- Video outputs: VGA, HDMI
- Cable: VGA to Composite & S-Video (not active, no scan converter)
- TV: Standard definition (SD). Non-widescreen. Supports PAL, NTSC and SECAM.
The problem I have run into is Windows will not allow me to set a compatible resolution to use for the TV. Consequently, the TV just shows the typical sort of distorted images you get from a mode mismatch. I figure there's no EDID information provided to Windows, so it's just using a generic non-PnP monitor driver.
I looked through Windows' list of built-in monitor drivers, and the closest driver I could find was Generic Television. However, even using this driver, Windows seemed to provide the typical list of VGA monitor resolutions. The minimum resolution I could set was 800x600, and the minimum refresh rate was 60Hz.
I think there could be multiple problems here that I need help with:
- The Generic Television driver doesn't seem to provide the right modes, namely 480i @ 60Hz and 576i @ 50Hz. I think I need a suitable monitor driver.
- Windows seems to have a minimum resolution of 800x600, which is too high.
- Windows seems to have a minimum refresh rate of 60Hz.
It's possible that the last two problems will be resolved in the presence of a suitable monitor driver.
Lastly, I would prefer an option other than using PowerStrip, since it's commercial software.
