My specs now

CPU: Intel(R) Pentium(R) CPU G2020 @ 2.90GHz
Motherboard: mahobay
Ram: 4gb
GPU: Galaxy GeForce 650 ti boost 2gb
PSU: CORSAIR CXM series CX600M 600W

Just installed a new gpu and psu. Installed lastest driver for gpu. HDMI works fine on the 55" tv and then I unplug and plug into the 32" i get a no signal i can either choose tv or hdmi source but end wup with black screen and no signal text floating.

So before I changed my pc parts i was able to use the same hdmi because my tvs are close to each other, they were working fine but now after i changed my psu and gpu, only one of the tvs are working with the hdmi.

  1. for starters, is the T.V. that doesn't work reading from the HDMI that it is connected to? Which is the simplest and almost always a yes response.

    Have you tried a DVI-HDMI cable if you have one?

    Don't have one. I am also using a rosewill hdmi.
  3. have you tried swapping around the cables?

    are you trying to run them both at the same time on the same card?
  4. I have two hdmi cord's. I want the pc to work on the 32" but its not finding the signal. The 55" is fine, it's for my game consoles. Also tried swaping the hdmi's.
  5. does the 32" T.V. connect to other devices via HDMI?,to work out if it just that input, the card's output ect..
  6. Well I took out the graphics card because I was building a comp and havent got all the parts yet but wanted to test out the card on my current pc. It was only showing up for HDMI on the 55" and not the 32". So after taking out the card and back to my normal PC specs I was able to use the HDMI on both tv's fine.
  7. could you do a little thing to try, Keep in your new PSU and try your old card, that'll determine if it is the PSU or GPU. As the If it doesn't work with the old GPU with new PSU, it'll point to the new PSU as the old PSU worked. If it does work with the new PSU, it points the fault at the graphics card as the old card worked with the new PSU.
  8. Didn't have a old card before. It was onboard. Also the new PSU works without the new GPU as well.
  9. oh, well it still will have the same outcome. You mean the new PSU works with the onboard GPU?

    This could suggest one of two possible scenarios;

    1) You have a faulty GPU

    2) Your GPU doesn't like these two different screens connected at once (resolution differentiation factor or other).

    Are both screens the same resolution?
  10. New PSU works fine with onboard GPU.

    55" is 1920x1080
    32" is 1066x768
    Same brand; Samsung but 55" is a Smart HD TV and 32 is just HD.
  11. oh ok, this could be where the problem lies, Your GTX 650Ti Boost may have issues trying to output to different resolutions, AMD cards tend to better at this and work better as their drivers have a vaster resolution support.

    Your card won't be faulty but will have an issue with the resolutions, you may have to return it for another if you want to power both screens.
