I'm trying to hook up my TV too my PC using HDMI cables. But my computer is using my Nvidia Geforce 9400 GT graphics card, which doesn't have an HDMI port. So I was wondering if there was a way to use the onboard HDMI port while using my graphics card. So far my nvidia control panel can't find my TV while I'm using the onboard HDMI port.

Thanks for any help.

The dedicated graphics card and the integrated graphics are not designed to be able to talk to each other or use each other's ports.

Your 3 options are:
1) Downgrade to integrated graphics so you can use your TV
2) Get a DVI-HMDI Adapter (these are $5 from newegg, monoprice, etc), if you want audio to your TV you will need either a 3.5mm to rca cable, or optical toslink (if both your TV and your computer supports it).
3) Get a newer video card

If your integrated graphics and graphics card are both AMD, it is usually possible to use both at the same time. Whether you can do it with NVidia may require some fiddling, I've managed to get it to work with an AMD APU and an NVidia GeForce 550ti after simply setting the primary graphics setting in the BIOS to "Built-In Graphics". I'm not sure if this is possible with your set-up, but it may be worth a try turning on integrated graphics in the BIOS and then connecting the output to the HDMI display. You'll need to use the Windows display manager to set up the displays as the AMD and NVidia control panels do not talk to each other very well.

OK, try inserting your graphics card and connecting monitors to the card and onboard graphics. Then boot into your BIOS, go to Advanced BIOS Features and set Internal Graphics Mode to UMA. If you have the same luck I had, it'll then either work perfectly or the drivers won't work properly. Try changing the "Init Display First" setting in the same menu on the BIOS to On Chip VGA (in fact, try all the options if that doesn't work). If it works, all the displays that are plugged in should receive a signal once the OS has booted.

Alright, well I tried setting Internal Graphics Mode to UMA which didn't work. Then I set Init Display First too onboard VGA. It worked but my screens are messed up. I click setting in graphics and its only showing 1 monitor, the same for my nvidia control panel. Any way to fix this? Also will this affect my ability to game?

If your NVIDIA graphics card is not set as the primary card, you likely won't be able to game on it. You may have to reset your BIOS so that your NVIDIA card is the primary, and possibly the only card in use, when you wish to use it for gaming. This is likely going to be an unfortunate trade-off of your situation. It's also possible that you won't be able to get the drivers to happily coexist and sort out the "messed up" screens. The equipment you are using just isn't well suited to the task you're trying to accomplish. I understand your budgetary limits, so I recommend you keep trying whatever setting combinations are available to you.

On the other hand, if you can get the configuration working properly, you might consider writing up a tutorial for others to follow. :)
