I posted this in another thread. I thought it good information for this thread.

I tested my 5300 using the test pattern posted on this forum somewhere. I forget what the pattern is called. It was the simple one with color bars. It passes if the input is set to PC, otherwise not. The display then uses "native" color space which my testing shows is not correct for playing DVD's using the computer, but the display looks so much better with everything else this way, this is how I run it.
PC mode also keeps the backlight from shutting off automatically when the screen goes full black which is a good thing, as this feature is not implemented properly. Meaning in non-PC mode, sometimes a fade to black ends up with the backlight blinking on and off when it should stay off. I did not notice how many fade to blacks there are in movies until watching in non-PC mode where this unit would flash on and off. Even if it did not flash, turning the backlight off took me out of the movie. I think this feature should have like a 15 second delay to be used as a screen blanker. That way if playing audio only, it will shut off, or if you set the screen saver to black, it will shut off. I wish that it was possible to use an input for audio only. If an input does not have a video signal, it cannot be selected. I saw nothing in the service menu to change this.
I like that you can actually use the light sensor on this model because you can set the minimum backlight and the maximum backlight. The regular backlight setting is what will be used when it is light, and the minimum setting is what is used when it is dark. This works really well. Sometimes it will go back and forth maybe two to three times when the light is right on the edge, but overall it works really well. It lowers the backlight when I would do it.
