SO we have a projector connected through a 50 ft VGA cable to a Win-7 PC. When we play a presentation usually within 5 min the screen goes blank then comes back on, as if the cable was disconnected and reconnected. this happens constantly through the presentation never stabilizing. I have installed new video drivers, in the PC's power setting i set all the sleep or hibernating options to off (do nothing). I also created a second user account on that laptop to test if certain setting on that account were causing the signal loss; but no luck the signal still dropped. However, when i connected a second laptop (Win-7) through the same cable, that signal was never dropped. Does any one have any suggestions on how to fix this issue?

What is the Maximum Length of a VGA Cable?

Answer

The maximum length of a VGA cable is 9 metres (29.5 feet); assuming the graphics card can develop that kind of signal strength. If this length is exceeded, a repeater may be required to maintain the signal quality.

I understand that the length of the cable could have been an issue. However, when i connected my laptop which is older than the laptop where using; can maintain the signal with out the screen ever going out.

Then apparently the newer graphics card is not able to develop the required signal strength.
