james3mc Posted August 31, 2006 Share Posted August 31, 2006 Need to display a Powerpoint presentation onto a video monitor. PC has : * Standard SVGA (15 pin D) * Serial (9 pin D) Monitor inputs are : * S-VHS - 4 pin minidin * Video In BNC * Serial (9 pin D) labelled RGB analog input * SCART (video input with neg sync; RGB input with neg/pos sync) So what's the eaiest way to get output from PC to this telly?

Tomo Posted August 31, 2006 Share Posted August 31, 2006 Pay no attention to the serial port on the PC - it's for serial I/O to things like old modems and various geeky stuff, NOT for video. The easiest inputs to use are the S-VHS (S-Video) or BNC (Composite) input - you'll need a box called a "scan converter" to convert the VGA output into either S-Vid or Composite.Places like Maplin do cheap ones.

Thanks for this. I've come across a lead (15 pin D to 9 pin D). Would that work, connecting the PC monitor port direct to the 9 pin D RGB input?

Tomo is right, the signal being output from a PC has a much higher scan rate and resolution than that of a video signal and therefore is not compatible for the video input you have this is why computer images are much sharper than video, you do indeed need a scan converter to convert from SXGA to video, however, if you are using a laptop, you may have missed the phono or S-video socket which are being built into most current laptops which will give you a video output.Do bear in mind that if you either use a scan converter or Direct video output you are effectively dumping 3/4 of your signal quality and the result will not be very good, especially for detail of small text. You would be far better off to get a monitor or other equipment that can accept the computer's output such as a projector, monitor or plasma/LCD screen.

As Tomo said, the 9 pin socket in a data comms socket designed to accept an RS232 signal NOT video or SXGA Link to comment Share on other sites More sharing options...
james3mc Posted September 1, 2006 Author Share Posted September 1, 2006 OK thanks everyone. The monitors are inherited and are already in place (ceiling mounted). It's just for showing a management summary - a kinda status overview - nothing fancy. So off to Maplins for a Scan converter - thanks again. james Link to comment Share on other sites More sharing options...
