Windows 7: Monitor Won't Accept DVI - HDMI PCs but 360 Yes

Hi guys... It was just this morning when I found that my DVI - HDMI cable was unplugged, it seemed that my Mom was kind of "super cleaning" my room, and she unconsciously removed the cable from my Samsung SyncMaster 2494. When I get to plug it back I find that the computer won't detect the monitor using the DVI - HDMI cable (Which has been used continuously for the past year and a half).

I decided to connect the computer via VGA... Poof, it works... Then I decide to test the DVI - HDMI cable with another device such as my Xbox 360. I plug it in, turn it on, and poof it works! I got astonished thinking that the output of my video card was damaged, and decided to test it with 2 more HDMI capable computers... Each of them DID NOT emit the signal nor detected the display.



I did a reset on the monitor, recycled the power, and I don't know what to do know... My Dell XPS M1530 (8600M GT) won't detect my monitor via HDMI anymore!.....

Help! Thanks XD.

P.S: ATM, besides the 360, I do not own a device which is HDMI capable.

Try uninstalling all the monitors listed in Device Mangler, shut down the computer, switch cables to the HDMI, then start it back up.

Did it, but it did not work.... It seems the problem is more with the monitor rather than the PC... Anyways I'll keep investigating it...

Edit:

BTW, thanks for the post

Guys, do you think it may be a faulty cable?

Not if it worked with your Xbox.

I haven't had an nVidia card for a while, but do you have any of their utility/monitoring programs installed? Maybe look around in there.

I'd double check in the monitor menu, too. Most of them have a range of input choices like Auto/DVI/HDMI/VGA. Try "Auto" first, and if it's no-go, set it to HDMI. (In other words, just monkey around with the setting and see if you get lucky.)

It seems is the cable. I've tried connecting the cable in another monitOr and it yielded the same results: no image displayed nor the monitor was detected. I'll be ordering a new cable soon and I will tell you afterwards.

A friend's theory, which it seems right. It seems that the cable has several pins broken (which at clear eye doesn,t seem so) and the xbox 360 DOES NOT need those pins either to detect the monitor or to display the image.
Although crazy, let's see what happens when I receive the new cable

****! I purchased the cable, and to no avail again! SAME Results....

:'(. I don't know what else to do. I did tried the old cable on multiple monitors to no avail... But now... my hopes are down....

Any more suggestions I can try?

Thanks again for the great help.

Have you tried the monitor on another computer? Did you try the menu on the monitor like I mentioned before?

Yeah, I tried . Dozens of times. But there are several statements to point out:

First, I need to have something connected for the monitor to show up the menu. (Which I use two 360s to do the job)

Second. I've tried using the force output with the Nvidia settings (to see if something comes up, including the TV output setting), but nothing!

Third. I've learned that the cable I just got, does convert the video signal to HDMI. I mean, the other cable had different pins than the one I got, and when I went to the 360's display settings it said DVI. Now with the new cable it says HDMI....

Better show you some pictures:
Cable 1 is the old cable.
Cable 2 is the new cable.

DVI is shown on the configuration on the 360 (Cable 1)
HDMI is shown on the configuration on the 360 (Cable 2)

I'll keep monkeying around with the settings to see if I can get to something... Again thanks a lot for the fast replies.

Is it possible that when the pins were bent on the old cable that it damaged the connection on the video card? Can you get us a good close-up shot of the card and its connections?
