Mitsubishi Megaview 37 (xc-3716C) resolution problems

I picked up a Megaview 37 for $50 off craigslist. Connecting to a PC via a HD15 to 5 bnc cable I picked up gives be a beautiful picture at 800x600. When I attempt to switch to 1024x768 or 1280x1024 the screen splits to 2 copies of my desktop, or goes to blue-screen (out of sync). On the other RGB  input using a DB15 to HD15 adapter, I get nothing at all.
If I connect through the s-vid input I can set my PC to 1024x768 just fine, but the quality is not nearly the same as with the VGA input.

Am I missing something here? Could my cables or the adapter from hd15 to db15 be the limiting factor? The picture on this monitor is fantastic I would really like to get the resolution higher than 800x600.

While searching for information on this monitor I stumbled across posts from some of the members who have or have had one of these monitors. I'm really at a loss as to where to go from here.

If there are monitor drivers I am missing, ( I could not find any) or some other little niggling thing that I need I really need the help. Using the composite inputs is ok, but if I can get the RGB/VGA straightened out I would like to try a HDFury on this thing for a progressive scan DVD player or console use.

Thanks in advance for any help you can give me.



Most all of the large presentation monitors like your unit top out at 1024x768@60Hz

What refresh rate at the XGA resolution are you sending to the monitor? 
Have you tried a different PC to see if the graphics card you experienced issues with is partially to blame? 

Also, most of the large CRT monitors don't look very clear when using over 800x600.  :-\  On top of that, if your monitor has seen alot of use, the picture does get fuzzier - especially at 1024x768!

The s-video connection you described is not sending a full XGA signal (resolution is down sampled when outputting via s-video).


1024x768 was originally introduced as an interlaced mode at about 43Hz. the last time i saw a video card that offered that timing was the s3 virge over 10 years ago. however many cards can still give out an interlaced signal via the use of EnTech's "PowerStrip". since the monitor can do 800x600 but not 1024x768(progressive) it should be capable of 1080i but probably not 720p if you are interested

edit: if it can do 800x600@72Hz, it might just be able to do 720p, they have similar horizontal scan rates
