HDMI connected monitor is blurry and seems out of focus

Hello, I built my new computer about a week ago and was running it off a single 19" Tevion TV while I waited for the HDMI cables to arrive so I could setup my second monitor.

They arrived yesterday and when I plugged in my 32" JVC LT-32DA30J there was overscanning and the bluriness. I fixed the overscanning in the TV's menu and now the size is correct but even at native resolution, the JVC monitor is still quite blurry and is a strain to look at and concentrate on.

Plugging the HDMI cable into my Tevion monitor made that go blurry as well so it could be the HDMI cable or the motherboard ports (when I first got the PC, the VGA port had the same problem but once updated it looked normal)

Does anyone know of a fix to this ? Or can at least suggest what part is going wrong so I can try and fix it ?

What I have tried:
Changing the resolution - all the different resolutions all show the same blurriness
Changing the refresh rate - problem persists through all refresh rates
Changing monitor settings - As above, changing these settings didn't help with anything

Any help is very appreciated :) , I've been trying to fix this problem for most of yesterday

Thank you for the suggestion :) I should of mentioned that I had checked for updated prior to posting and the Intel HD drivers are all up to date. I have just tried a different HDMI cable and it gave the same blurriness as the other one. I checked that they are not faulty as I plugged my Xbox into the same monitor using the same HDMI cable and the picture was clear and crisp.

Thanks for all the replys guys :) So the problem is more than likely my TV and not the cable or mobo? I had it connected with a VGA from a laptop before and it looked fine so would connecting it with VGA be a better idea?

I'm looking to get a GTX 750ti made by Gigabyte, would that be of sufficient quality ?

Awesome! I suppose I'll have to wait for that then. Thank you for all your help :)
