Hello,
I've been messing with this problem for about 3 weeks now and still haven't figured out what the problem is, but I do think I may be onto something. I was hoping someone here might be able to offer some insight.
Here's the deal, I have an InFocus X1 projector and I want to use my Supergun/MVS setup with it. When I try (using the s-vid out on the JROK to the s-vid in on the X1), I can get a picture, but the bottom is cutoff, the screen bounces, and the screen flashes.
I have tried to use two different MVS boards (1-slots) both of which run into the same exact problems. I have also tried a homecart system which worked absolutely perfectly!
I originally thought the problem was that the projector didn't support the neo's resolution (320x224), but that hypothesis failed when the homecart worked perfectly.
I have tried every single video setting on the projector and double checked everything. I am still at a loss and am only getting more frustrated
After doing some more thinking and research, I am starting to think that the problem is with the Horizontal Frequency output by the MVS. Using the JROK as I understand I am outputting a 15kHz Horizontal Line Frequency. The projector's specifications (found at: <a href="http://www.infocus.com/products/productview.asp?site_lang=1&site_region=1&prod=x1&c=4)" target="_blank">http://www.infocus.com/products/productview.asp?site_lang=1&site_region=1&prod=x1&c=4)</a>
list the H-Sync Range: 31.5 – 80 kHz
and the V-Sync Range: 50 – 85 Hz (85Hz at XGA only)
This is something I didn't notice before. My guess is that the projector can't properly sync with the MVS as the MVS is at 15 and the projector can only go as low as 31.5
Can anyone comment on this? Am I on the right track?
Could anyone please offer any suggestions as to how to solve my problem? I'm going to look into using an upscan convertor (as the projector can accept VGA) to hopefully bring the signal of the MVS up to a useable level with the projector.
Can anyone suggest a good upscan convertor to use?
Any comments or suggestions are greatly appreciated as I am almost at a loss here.
Thank you very much!
