I have been trying to find an answer for my problem online since yesterday but as I cannot seem to find a solution I thought I would try asking asking here!

I have had my PC since June last year. I noticed when I first set it up that one of the HDMI ports wouldn't give an output to my HD TV which is my monitor. It only connects to the lower HDMI port which I assume is straight into the graphics card but not from the other one higher up? My PC has 2 HDMI ports at the back and has a NVIDIA GeForce GTX 750 Ti graphics card which I've heard can support up to 4 displays? At the time it wasn't an issue and I have been using the lower HDMI port to my TV since then.

I am an animator/game designer and yesterday I upgraded my graphics tablet from a Wacom Intuos5 which simply used a USB connection to a Wacom Cintiq HD (the screen based graphics tablet). This tablet naturally uses a HDMI cable so I now need to utilize the HDMI port in my PC (or find another way) as at the moment I am having to EITHER use the Wacom Cintiq OR my monitor swapping them out - not both at once (I would need it to be a standard dual screen extended setup).
I tried inserting the HDMI wire from the Wacom Cintiq into the HMDI port that doesn't seem to work and I had nothing from it as I expected - I'm not sure if this is what I'm supposed to do to get a dual screen? I'm really new to this and not super with hardware. I did manage to try it with a VGA cable on my TV monitor and the Wacom in HD which worked but I need both to be in HD for production work.


Would I need some sort of adapter for it to work? How do dual screen setups work off this GFX card - I haven't done dual screen before? Is there a setting on my PC I need to turn on to make the other HDMI port work? (I assume the other HDMI port is just connected to the motherboard as it's a little higher up than the one that works). Is there a way to get the Cintiq working and my TV monitor using just one HDMI port from my PC? I'm open to trying anything needed but I just need both my TV and Wacom Cintiq to be in HD, working together.

I would be so grateful for any help.

Thank you very much!

From what I have read, you are trying to connect to the onboard graphics (the higher up one) aswell as the GPU HDMI. These will not work together. What you need to do is get an adapter to convert the display port to hdmi.

I hope this answers your question :)
[One More Edit] VGA outputs in HD it is just an analogue signal, it will still output in 1920x1080+
 


Thanks for the reply (And the diagram -it did help!).

From what I can see there is no display port like the one in your image on the back of my graphics card - there is HDMI, VGA and DVI I think? Image here: http://m2.agitomedia.pl/image/700x700/0/karty-graficzne/msi-geforce-gtx-750-ti-oc-2gb-ddr5-pci-e-box.2018153.2.jpg

So I assume I cannot use the adaptor?

When I use VGA my monitor doesn't seem to be in HD, the colours aren't anywhere near correct compared to when it's hooked up with the HDMI lead and the ratio messes up even though I tried to correct it with my TV remote.

🙁
 


The colours will be not as good with VGA but that is irrelevant because you can convert dvi to hdmi aswell as dvi is the same as signal as hdmi.
DVI to HDMI converter:

Just hook that cable up from the dvi on your gpu to the hdmi on your display and that should solve your problem.
