    Default A small problem connecting my pc to a new Vizio 39" Tv :/

    Just got a Tv as a present and connected my pc to it using HDMI, but the picture looks grainy i guess? Not sure what else to describe it as besides just that. It is a 39" 1080p 60Hz Vizio Tv and my graphics card is a PNY Geforce GT 640 and both native resolutions are at 1080p. I have so far changed the connection name to "HDMI PC" but haven't changed any settings in nividias control panel as they seem to be all set correctly. Any ideas?

    How does the picture look using a cable box, dvd player, sat or over the air HD?

    How close are you viewing the image?

    Are you using a newer HDMI spec cable? Think HDMI 1.4 -2.0 should cover everything you need. Of course newer is better. If it is an old HDMI it may not be able to carry the data for clean 1080p.

    Try different HDMI port

    Connect a different PC or Notebook to TV and see if the picture remains grainy.

    I'm with Sandy on this. Likely the cable. A decent cable from MonoPrice or Amazon (I've used both AmazonBasics and BlueRigger cables) will likely solve the problem.

    Keep in mind that when you are using a PC connected to a TV rather than a LCD monitor while having the same resolution the Pixel density is not he same on a larger screen.

    Imagine placing a 1080 PC monitor that is 24" then, now the same 1080p on a 55" TV. The pixels will look much larger on the TV which in most cases tends to make wording not as sharp on a TV. So it may have nothing to do with your hardware.

    What I have done in the pass is increase the viewing size from 100% to like 125% on the TV. But this will also change the size on your monitor.
    This will help with what seems to be like a clarity problem what you are having. or you can try to run calibration in windows to help sharpen the image when it comes to text.

    Now, not all TV's are like this. Some seem to be more sharp then others, but in most those cases it's the panel that makes the difference.

    What model TV are you using?

    If this isn't the case, then try changing to a better HDMI cable or what the others have said above.

    I'm currently using a cheap Vizio 6ft HDMI 1.4 cable i got on black friday that is not gold plated so it wasn't the best quality. The TV is a 39" E-series Vizio model: Vizio E390-B1E. I also have a gold plated 1.4 HDMI cable i had laying around that i tried as well and it does the same thing in either HDMI port. The PS3 looks great on it though so i guess something in my PC (Graphics card) settings that could be causing it?

    Honestly the gold is irrelevant, but 2 cables doing the same thing do indicate a problem at the source or receive end, instead of with the cable. The PS3 connection would indicate that there's nothing wrong with the receive end (the TV) as well.

    Since the output of the PS3 is not generating graininess, what exactly are you displaying on your TV from the PC. Are we talking video (i.e. Youtube, Netflix, DVD) or your Desktop? If you are showing your desktop, are do you have a background image, or a monochromatic background color?

    If you're running video, it's likely the noise is being caused by your decoder, or the source media is not as high a resolution as your screens. In this case, pixelization would appear on your TV screen because of pixel size (as Kenny pointed out), while it likely would be hard to see on the computer screen. Also, some pixelization can occur even at high resolution, even if the source material is 1080P due to compression/decompression, or decoding/algorithm inefficiencies/bugs.

    Consider trying an application like: PassMark MonitorTest - Test monitors and LCD flat panel screens to run and check your monitor and tv, this may point out where the problem is occurring (in other words, if the test screens look good, we can look at the source material).

    Your settings could be incorrect for the TV, but as long as the resolution and frequency are correct, it's unlikely. I expect it's more likely the source material and pixel size.

    Love this guy here. So glad I picked him up from that corner that one night.

    Seriously all valid points and sounds troubleshooting.

    I have a feeling it is strickly related to that 640. What CPU are you running are what Video outputs are on the board itself? Does the board (not 640) have HDMI out or DVI out(will need DVI to HDMI adapter) to plug directly into? Or use a different GPU. For an HTPC you dont need much. I have used low end R5 models or the just the AMD APU.

    Need to try it without that 640 one way or another.

    Also check your w7 display settings, and chage it to TV instead of monitor (I think it's posible, or I just talking crap).

    Always look beyond the limits...

    Just desktop right now but i also tried some video and it was the same. The background image is very grainy for me no matter what background i use. I will check out that application and see what i get. I do have other HDMI connections on my MB so i can always give that a try.

    Tried the test out and had no distortions on either screen. I am using a very high def desktop wall to get rid of any graininess for the desktop even though most 1080p walls look grainy still, video is alright as long as it's not very compressed 1080p video and games still look a bit weird on it. The video sources are all correct so i'm guessing it is probably pixel size like Scott had said before.

    Seriously all valid points and sounds troubleshooting.

    I have a feeling it is strickly related to that 640. What CPU are you running are what Video outputs are on the board itself? Does the board (not 640) have HDMI out or DVI out(will need DVI to HDMI adapter) to plug directly into? Or use a different GPU. For an HTPC you dont need much. I have used low end R5 models or the just the AMD APU.

    Need to try it without that 640 one way or another.
    Scott does get right down to the technicalities of things. I always appreciate his input when looking for an answer to a problem. Confusing sometimes to folks like me but thats how I learn.
