    I have my desktop computer connected to my TV via a HDMI cable. Being like this for the past two years without issues.

    Recently, my TV is not detecting the computer and I'll need to restart my computer one or two time in order for the TV to detect the signal from the computer. I know it's NOT the TV's issue because when I connect it to my laptop, it has not problem detecting the signal from the laptop.

    OS: Windows 7 Computer Video: AMD Radeon HD 6500 Series TV: Samsung PND8000

    Anyone know what's wrong?

    colors - Why does black show as brown when computer connected to TV via HDMI
  • Andy

    I normally use my computer connected to a DVI monitor using the computer's HDMI out. I tried connecting it to my television and there's a brownish tint to everything (any black backgrounds show up as brown). White is still white. If I use the TV menu, all the colours on the menu show up fine. I have a dual-booting machine with Win7 and Ubuntu. The problem occurs with both OSs, and in fact from the moment the machine's switched on (initial boot, GRUB menu, BIOS settings). The TV has three HDMI ports and I've tried with all, no joy. If I use the TV's VGA port then the colours are fine. All drivers and BIOS up-to-date (from Dell's site). Any ideas?

    Edit 1: It's worth mentioning that the effect is not subtle: the blacks are displayed as fairly rich browns, so I don't think this is down to a small colour mistuning somewhere.

    Edit 2: It looks like it might be an issue with Samsung TVs. Here are some issues that sound related:

    This may be the colour temperature setting on the television. Most televisions have a setting where they can tint the image to change the feel of the image. Colder, bluer colours enhance darker, more eerie films, whereas a warmer red or brown tint is better for happier more 'normal' television viewing.

    Check the TV's menu for possible entries like Colour Temperature, Tint or Hue settings and have a play with those.
