Issue

TV does not display a picture when hooked up to a computer using HDMI and or VGA connector.

Procedure

Computers can output a wide variety of signals, some of which are not compatible with LCD/LED TV's. If the TV shows a message on the screen similar to: "Unsupported Signal or Video type" the output from the computer is being recieved by the TV but the signal is of a resolution or frequency that is not able to be prcessed by the TV.  Not all models support all resolutions.

Some guidelines for best results:

  1. Always adjust the computer dispaly settings using your existing monitor before hooking up the TV.
  2. Always use a frequency setting ( scan rate) of 60hz, the TV may not recognize any other setting.
  3. Start with a lower resolution setting like SVGA ( 800x600) or XGA (1024x768) when using the analog VGA connector.
  4. When using an HDMI cable to connect the TV to a computer start with a resolution of XGA(1024x768), WXGA(1280x768)(1360x768) or 720p (1280x720).
  5. Smaller screens that have native 720p or 768p panels generally will work best if used with WXGA(1280x768)(1360x768) or 720p (1280x720) settings with the TV's picture size set to either NATIVE, NATURAL or FULL depending on model.
  6. Larger displays (1080 panels) will generally work best if used with WXGA(1280x768)(1360x768) or 720p (1280x720), SXGA(1280x1024) or 1080p (1920x1080p) with the TV's picture size set to either NATIVE, NATURAL, or FULL depending on model.
