TV as PC monitor Windows 7

    Question

  • Hello,

    I am using a UN32EH5000F 32'' TV as my monitor. Its connected by a HDMI cable with a DVI adapter on my PC.  My Gpu only has DVI slots.

    Its great as a monitor, but I have been having signal issues. The TV has been arbitrarily losing signal. This is usually random, I could be okay for a few days then while watching a video it drops the signal. A few triggers I have noticed to cause it are when my PC sleeps or when I press Ctrl+Alt+Delete.

    I have the latest graphics drivers and TV firmware installed. The TV is set to HDMI [PC]. The HDMI cable is brand new I bought off Ebay.

    I have called Samsung and they could only recommend I try a new HDMI cable or send the TV in to them see if its faulty. I dont suspect the TV or HDMI cable to be at fault. I have read forums with the same issue, changing the HDMI cable never appeared to solve anything.

    Some have recommend to cover a pin on the HDMI cable with tape [Which doesnt seem to work for me] because its responsible detecting a signal, and if there is none it drops.

    Another thing, the TV makes a windows USB connection sound when plugged in. Maybe this has something to do with Plug and Play?

    I would really appreciate any help. Im getting desperate.

    • When the TV signal goes out, no USB unplug noise is heard.
    • It is set to native 1920 x 1080.
    • Everything is set to 1920 x 1080. I dont believe its the resolution causing issues though. I regularly play Age of Empires 2 at lower resolutions and never have issues.
    • I watch my movies with VLC player as well as videos online such as with flash on Youtube. I do put them in full screen.I recall watching a youtube video maximized... 15-20 minutes through my TV decides to not see the signal anymore.


    That leaves only two things, your TV has a bug or your its your Video Card.

  • A couple of thoughts here:

    Is your TV going to power save mode? Some TVs automatically turn off after being on for a certain period of inactivity preserve longevity.

    Did you turn off all of the power save options in Power Options? Control Panel > Power Options > Change Power Settings > Change Advanced Power Settings

    • Expand Display > Turn Display After > Setting : Never

    If your computer is going to sleep, naturally the TV is going to turn off as well. The power options will most likely be the best case scenario.

  • Hello,

    All power settings are off. This goes for the TV and my PC. It does not appear to be anything related to power saving, the TV simply loses signal at random.

    Im hoping I can figure this out before monday! Im using a backup monitor right now.

  • A few other thoughts:

    • Has it ever worked consistently? It could be your TV design or how it senses a signal / or signal inactivity.
    • It could be your DVI to HDMI converter.
    • It could be the refresh rate of your system.
    • It could be "resolution switching". When you switch between applications, different applications will take away "windowing" and run in "full screen mode". When it runs in full screen mode, it may be changing the resolution into an unsupported format.
    • I've also seen it being a faulty/dying Power Supply. If your video card is being powered from the power supply (not just pci-e power source), and the power dips, it can cause issues with your video, and screens shutting off.

  • Thanks Brenton,

    • No it has not. Ive always had a issue with it one way or another with the random signal losses.
    • Possibly, I will try and to find another one although its a new adapter.
    • The TV and my computer are both running at 60hz
    • I believe this could be a possible contributor to the problem. Although I could have instances where im watching a video and out of the blue it drops the signal.
    • I am running a X3 1000W power supply powering my 260gtx GPU. Although I don't suspect power to be the issue.

    I keep having a hunch its something to do with Plug and Play. When ever I plug in my TV windows makes a new device sound (The same when you plus in a USB). There was also some talk about HDMI has a signal detector in the cable and when ever theres a drop it drops the entire signal, hence the reason I must unplug the TV from my PC and unplug the TV's power for a couple minutes and restart everything.

    When the monitor goes out, do you hear the USB unplug noise?

    What resolution is it set to? it says the monitor only supports up to: 1920 x 1080

    What are your games / programs setting the resolution to? I suspect it is an invalid format.

    What program are you watching the movie on? Is it forcing full screen?

  • Also, try turning off Film Mode. I wonder if the "auto adjusting quality" is messing with signal back to the computer.... if it is random or when you are doing something, I suspect its this that is changing some sort of signal.

    When the TV connects to the computer, does it say 1080i? 1080p? Does it give a resolution? Is it down converting to 720?

  • Film mode is set to off and the TV is set to Mode: Standard.

    When it connects to the PC it Says "1920 x 1080 @60hz". It is not converting to 720p.
