Windows 7: Win7 will not recognize HDMI

19 Jun 2014   #1

Microsoft Windows 7 Ultimate 64-bit 7601 Multiprocessor Free Service Pack 1
Win7 will not recognize HDMI

Clean install with Win7 Upgrade - I have done this many many times w/out issue.

I have two almost identical desktops (gateway) both from 2010. The only differences were the Vid card and processor, everything else is the same. One had a fried checksum so I combined the two, hardware wise.

The video card is a GTX 460.

I think I made the mistake of installing windows 7 with a different monitor using the VGA port and this is why it won't recognize my HDMI. The monitor I'm trying to us w/ HDMI is a samsung 23'' Px2370. I have tried all combinations of unplugging both monitor, and only booting to the HDMI, and the screen is black. I go into the control panel settings and the HDMI monitor is never recognized, never shows up any any lists. This includes turning off and on the monitor before and during initial boot.

I've updated Win7 completely. Installed and updated all drivers (appears that there are no conflicts), including the driver to the monitor, which I have never had to do since I bought it. I even tried a different HDMI cable.

I'm at the point where I'm thinking I'm going to have to reinstall Windows from scratch to get this working, or at least the OS to recognize the HDMI output. Really trying to avoid that if possible.

I feel like I've tried everything. Any Advice ?

.....and since I'm here, eventually I wouldn't mind setting up two monitors. Is that Possible with one monitor being VGA and the other HDMI (preferably w/ two desktops, not a copy of the primary monitor ????

Does the HDMI on the monitor work itself? Does another HDMI monitor function? Could be the HDMI ports that are broken. Nothing to do with drivers or that Windows was installed with a VGA monitor.

The HDMI monitor works, along with the cable I'm using, however I personally have never tested the port on the desktop. I've considered this already, but I don't know how to test it.

I also know that the HDMI port on the desktop has never been used.

When you installed windows, were you using the video card or the motherboard to connect to the monitor ?

Or did you use the 460 the entire time ?

Stupid question, but did you change the input on the monitor to HDMI, or does it do that automatically ?
