Nvidia Graphics Card + DVI Splitter = Oh Gawd

Shorn Scrotum ManShorn Scrotum Man Registered User regular
So, I have a Nvidia 7900 GS. For the longest time now I've had a 17" Widescreen LCD and a 19" Widescreen LCD plugged in to the 2 available DVI-I ports. This has been a setup that has worked perfectly for me.

Enter the 42" LCD Television we got a couple of weeks ago. It had a spare HDMI port that wasn't being used for anything, and I noticed they made DVI-HDMI adapters, so I pick one up, and it is glorious. Nothing like playing games on a 42" HDTV.

But removing the monitor cable from my monitor to plug into my tv is a hassle, and I am a very lazy person. So I purchase myself a DVI splitter and another DVI cable.

And, for a few minutes, this worked perfectly. Then, when I attempted to run a game, both the TV and the monitor plugged into the speaker go dark, and everything that should have been on those screens gets shoved onto my other monitor along with the crap that was already there.

So as near as I can tell my graphics card is freaking because it's detecting 2 separate monitors plugged into that DVI port. Instead of trying to figure it out it just shuts down the signal flowing from that port. As soon as I plug in the TV or the monitor by itself, everything works fine, but together they refuse to work.

Has anybody dealt with this, or know how to fix it?

    Does the DVI splitter support HDCP?

    I had this problem before, but instead of it going black, it simply forced my projector onto a resolution that it couldn't support (yet the monitor did). I read a while back that it has something to do with how the graphics card receives the monitor information (support resolutions, etc) and it can't cope with info from both. I'm not sure how true this is, but sent the splitter back and just bought a USB DVI extender.

    I tried something similar but instead of going dark, I received a really fuzzy image. Obtaining a switch instead of a splitter solved my problem since I never used the TV and the monitor at the same time. Maybe that solution will work for you?

    How would that work? I thought a splitter was supposed to share 2 sources with one monitor/computer. Can it be altered to split one source to 2 separate monitors?

    Because that solution would be ideal, since my setup sounds like yours. While I'm using one I have no need for the other.

    Not really, which is part of the problem. I purchased the splitter for that very reason and found out pretty quickly that such a solution wouldn't work so I had to resort to plugging one in at a time.

    Sorry, got that wrong because intially I did have a splitter in my chain, but what I also had was a Powered Splitter. Currently I have a TV tuner running out to a powered splitter and then to two separate monitors. Originally I had a monitor that only had one input so I then had a switch between the splitter and the monitor. I have since removed the switch since I purchased a monitor with more than one input.

    Oddly enough, monoprice does not have powered DVI splitters. I see VGA and HDMI powered splitters, but no DVI splitters. I can find them elsewhere, but they seem to start at around 100 bucks.

    Here's one I could find on new egg. Would this work? Also, the review kind of sucks.

    Edit: The reason I don't mention the same thing I bought is because my powered splitter is actually VGA.

    That'd be nice to try, but I can drag my ass off my couch to switch a cable real quick instead of paying $100 :-/

    Totally understandable. It's why we currently have a manual switch for our ADAT Optical to switch between the PS3 and cable box.
