Trying to connect my PC to my D20F1U via Extron RGB 203 Rxi

Post by Plazmunky »

What the title says. I'm having difficulty getting my PC to display properly. I'm connected via d-sub 15 to the Extron.

The D20F1U supports 480p/720p/1080i resolutions and I would like to get a clear 1080i image preferably. However even after fiddling with the DIP switches I can't seem to make the image clear.

Picture example with DDSP switched on while sending 1280x720:

This looks good aside from the strange bending of the picture at the top.


Picture example with DDSP swtiched on while sending 640x480:

Strange streaks in the picture, just all around terrible image.

Really kind of lost here. Turning off DDSP makes the image way worse on both signals. Turning on SERR (serration pulses) makes the 640x480 colors way better, but only with DDSP off. Am I going about this correct way?

which kind of sync signal do you use from the RGB interface ? For convenience (and compatibility) you might want to try RGsB instead of RGBs.

1080i I way above the screen's physical (horizontal) resolution. If you have to feed HD, go with 720p.

It's connected to my video card's DVI-I port with an adapter to VGA. GTX 980 Ti. I'm assuming it's just RGBHV.

I've tried using RGsB and for some reason, I'm starting to suspect my Extron has issues. The SOG switch just doesn't do anything. It doesn't send a sync signal over green at all, it just continues to send it over the S BNC output.

Yeah, I suppose that makes sense since in 16:9 mode it only displays 700 lines of resolution anyway.

The dedicated "S" output plug will always provide sync. The SoG dip should just add sync to the green signal. On your BVM you have to switch to internal sync usage.

Right. Whenever I was testing in the first place, I swapped the sync method to INT (internal) from EXT (external) with still no result. It's receiving the colors but still no sync even though the SOG switch is on. I use internal sync all the time with this set so I don't think there's an issue with my BVM in this scenario.

Didn't know that it would still send sync over S regardless of SOG on or not, thanks for that tidbit of information.

Hmm, indeed sounds like the problem is with your interface. To be sure I would check the internal jumper configuration which allows you to switch sync polarities....

Yeah, the manual said something like that. I suppose I'll give that a go and report back when I've tried it.

Now that I found time I got to doing this finally. Unfortunately the same exact result. Not at any point is the SoG dip switch sending a sync signal no matter which way I arrange the jumpers inside. The S port's sync signal gave me the same exact results I pictured earlier as well. I really am beginning to suspect the Extron now.
