I have a 24" monitor and my PC's motherboard has a HDMI port but I dont use it as I have a GeForce GT 640. So my monitor's HDMI is connected to the graphic card.
Now I am thinking to but a TV and add to the system. But on my graphic card I have only one HDMI, plus a VGA and another port which doesnt look familiar but I thing its DVI. So anyway, where should I connect the TV to? The motherboard's HDMI? OR use DVI instead? Wouldn't it reduce the quality if I connect it to the motherboard's HDMI ?

If you connect the TV to the motherboard it may not even work, depending on the motherboard itself and the CPU you have. Typically this requires settings being changed in the BIOS to accomplish.

You can connect the TV to any of the available ports on the graphics card and it should automatically detect it. You will need to change some settings in your OS to expand your desktop to the TV, as well as configure the resolution, but it should detect it right away.

Note that DVI and VGA do not pass audio, so you will need to figure out a solution for the TV if you want to keep using HDMI for the monitor. HDMI passes audio, so it may be best to switch the TV to HDMI output, and the monitor to DVI.

Thanks for your answer. BTW my monitor has 2 HDMI ports and one VGA. If that helps. The motherboard HDMI, VGA and DVI are working. Once I tried to connect om old small screen to it and it simply worked, like a double screening. The quality wasn't good but dont know if that's for the old monitor on the motherboard port.

The other problem is that my monitor also has speaker and the HDMI cable does the job for it. So what it I get a HDMI to DVI for the monitor and a HDMI to HDMI for the tv ?

What are you going to be using for your main sound device, and what will be your main display? If the monitor is going to be your main screen, and the speaker on it the main audio, use the HDMI out on the graphics card for it. Same applies if the TV will be the main display and sound device. If the motherboard output is working, use an HDMI cable from there to the secondary display, but note that it will not carry audio with it.

So just prioritize your displays and audio devices, is basically what I'm saying here. Use the graphics card output for the best/main one, the motherboard output for the secondary one, since it is apparently working. I'm glad to hear it wasn't a nightmare to get the motherboard output working.
