Hello,

I have a VGA port on my PC, when I connect my monitor via a VGA cable (cable confirmed to be working) there is no response. I have looked inside and the port is connected to a board of some sort (as far as I can tell).

Here is a picture to show what's going on:

from that photo, I can surmise that your computer has both a integrated graphics card, and a dedicated graphics card. The integrated graphics card, is the one on your motherboard, that the VGA port, and the upper HDMI port, are connected to, and the dedicated graphics card. The way most computers work, is when you install a dedicated graphics card, it automatically disables the integrated video card, which is why your monitor doesnt work on the VGA or the upper HDMI port. You can fix this by either removing the dedicated graphics card, or disabling it in the BIOS, however I think if your dead set on using VGA, I think your better off getting an DVI to VGA adaptor such as this and hooking your vga monitor to the DVI port of your dedicated graphics card-using the integrated card slows your computer down.

Thank you for your clear explanation t_p. Now I understand why the ports aren't working now and that I can't really use them.

It seems I have a somewhat awkward set-up. I have a dual monitor set-up, with one monitor that will only take a VGA input and another monitor that will only take a DVI input. I tried to use the working HDMI port to connect to my non-VGA monitor, but I was not able to get the monitor's maximum resolution via that connection (which I need for work). As you can see my single working DVI port is not enough!

Do you know of a HDMI to VGA adaptor?

unfortunatly, no I do not know of such an adaptor. It may be a driver problem-what kind of computer do you have, and what kind of video card is it do you know? and what OS? If you dont know what kind of video card it is, you should be able to find it in device manager. (right click my computer, it will be on the left hand menu in both vista and 7. you should also be able to access it by right clicking my computer in xp as well, though the menu is different)

Are you referring to why I cannot get the maximum resolution using a HDMI cable? If so, I recently made a thread asking for help here, where I detailed the specs you asked about.

aaah, well in that case I agree with dpunishers solution-you have the incorrect cable.

OK. Thanks for the feedback. I guess I will have to make a compromise between one monitor and it's best resolution or two monitors and lower resolution, as I have now.
