  1. No image on display while cloned with the TV, but with image on TV


    Today I saw there was no image on my display. I opened my TV to see what's going on (my pc is permanently cloned with it) and there the image was in its full splendor. I tried to set again my nVidia settings while I was running between one room and another (my pc and my TV being held in separate rooms), but it seemed everything was alright. I have restarted many times my pc, and the result was always the same: the monitor's led, after yellow, became blue, the image showed up for a quarter of a second and then the display turned black (with the led still blue), while on the TV the image was correctly displayed. What is to be done? Help, please.

    :)

    Does a 1080 tv ever display an image correctly...

    The 3rd HDMI input is the same as the others.

    To show the problem that's happening, I've set up the TV's HDMI and VGA as multimonitor and cloned with both running 1920x1080p. I have both a VGA cable and an HDMI cable running from an HD7770 to the TV. I can now use the TV remote to switch between the two and compair. To get the HDMI signal to fit the screen, I have to use ATI's underscan feature found in CCC.

    There may be some moire distortion from my camera. Please ignore that.
    The images are as follows.

    First image: HDMI 1080p full screen.
    Second image: HDMI 1080p close up of problem with fine lines.
    Third image: VGA 1080p full screen
    Forth image: VGA 1080p close up of fine lines properly displayed.
    Fifth image: 1920x1080 test pattern. View full screen to test your display. It should look like the forth image. If not, your scaling.

    The fix for everyone one of my crappy looking tv's via an HDMI/VGA/DVI input has been to disable scaling within the TV. The issue is the TV tries to scale all images including 1080P coming into it in order to remove the possibility of inputs not outputting a full 1920X1080.

    Does a 1080 tv ever display an image correctly...

    AMD drivers have a bug that sets the over/underscan option to a value other than 0 when using HDMI with a HDTV. So there is a black boarder around the image on the TV and the image looks like crap. That is what he is talking about.
