I was wondering if anyone knows if the RGB/SCART input of a 100Hz TV will accept a 100Hz RGB signal.

Thanks

I investigated that issue a couple of months ago. From the specs I could find on the net, the answer is no.

Still, there might be some TV set out there that is capable (I assume you're thinking of using it for shutter glasses with a computer). My search wasn't thorough... mostly focused on Finlux and Grundig products

There might be some US HDTV sets that can do it. The HDTV specification contains e.g. 1280x720 at 60 frames per second, and such a TV might be able to run at 100 Hz if resolution is reduced. Pure speculation, though.

If you continue looking and stumble upon a TV set that can do the job, please let us know.

TV-sets are designed to adhere to TV-standards and there is no 100Hz TV-standard.

There are projectors and maybe Plasma or LCD screens which accept a 100Hz progressive VGA-signal, but they will convert it to their internal rate which is usually around 60 Hz.

The best choice for 3D is an analogue multisync CRT-monitor or multisync CRT-projector.

Thanks for the replies.

I was reading through the specs for a 100Hz TV chip set which stated that another application for the scan rate converter was for a DVD player. I assumed that a 100Hz DVD player would require a TV which would accept a 100Hz TV compatible input. Of course they may not be aiming this at the consumer market.

I was considering building a simple 50Hz to 100Hz ABAB scan rate converter (non VGA) for watching interlaced stereo VHS tapes playing on a standard VCR.

I need a monitor which will accept some form of 100Hz TV signal. I am thinking of replacing my current TV and this seemed like a good opportunity. I have seen the Monivision range, which would probably work, but these are fairly expensive so I was hoping for a cheaper and more main stream solution.
