How can I tell if my PC is HDMI compatible?

HDMI video card doesnt output HDMI signal to monitor?

• Ok so I just bought a new tv and a new video card. I installed the video card, connected the card to the tv using hdmi, and turned on the computer. Computer booted up fine, let me know there was a new video card and that I needed new drivers. I could see everything fine from my computer, just had the wrong resolution for the tv due to not having the drivers installed. So I went to ATI's website and downloaded the appropriate drivers for my card. It went through the whole install and said everything was installed fine and needed to reboot for changes to take effect. So I clicked "OK" and it rebooted. When the computer restarted, I could see the initial start up screen and all that including the windows logo right before the logon screen. Right when the log on scree was about to show, the monitor said "No Signal" and turned blue. I knew from just always being on how to log on to my name without seeing it. So I did that, and heard the start up sound (when it shows the desktop after a restart), but still no image on the screen. Any ideas how to fix this? It worked without the drivers, as I said before, but wasn't the right resolution, so didn't look right. I also have a DV-I port on the card and using a dv-i - HDMI adapter, I tried to connect the TV through there and that was a no go as well. I also tried renaming the HDMI-1 channel to "PC" which people said to try, and that didn't work either. Any help would be greatly appreciated. And please don't tell me my TV or card is shot because they both work up to the log on screen. And the TV works fine with my XBox hooked up to the same HDMI port running 1080P. Here's the info about the card and TV: Card: ATI VisionTek HD4350 512MB DDR2 memory TV: Philips 32PFL6704D/F7 32" 120HZ Full 1080P Oh also, when I hook up the HDMI from my computer to another HDMI port on my TV (HDMI 2/3/4) or back to the original, it makes that weird noise like when you plug in a USB device or memory card, and then makes the other noise about 2 seconds later as if I disconnected whatever was plugged in. I can't see my desktop, so I don't know what it's saying or doing.

• Answer:

  I've seen this before on several systems that I've built. It is usually the resolution or refresh rate set too high for the TV to handle. Remember, that TV is not a computer monitor. Computer monitors have a signal they send to the computer, letting it know what its limits are. Your TV might or might not play well with a computer (reporting to the computer its resolution and refresh rate limits). Boot into safe mode: http://windows.microsoft.com/en-us/windo... ...then set the resolution and refresh rate below what you know your TV should display. For most TV's that are at least 720i HD resolution, set it to 1280 x 720, 60 HZ vertical refresh rate (found in the "advanced" section of the resolution settings). Once you do this, reboot the computer, it should work just fine after that. Once you get booted into Windows, you can then set the resolution for the maximum your TV can handle. For full 1080p HD TV's, the resolution is 1920 X 1080, at 59 or 60 Hz refresh rate. You should also find out if the TV manufacturer has put out a Windows7 driver for that TV. Some of the better TV companies have drivers for their HD models, but all they really do is tell the operating system what resolution and refresh rates the TV can display.
