Hit the Phase button

Originally, we encountered terrible problems with interference on the LCD. We noticed this early when trying to play Max Payne 2. Unfortunately, whenever Max or Mona would get hit on our screen, our signal fell apart and we would get a burst of static. We originally blamed this on horrible interference over the DVI interface and called Albatron.

Fortunately, problems were not as severe and there was a simpler answer. One of the least documented functions on the On Screen Display is the Phase Adjustment. All this does is adjust the noise level of the signal itself - if you have a signal coming to the monitor that shows signs of interference, the LCD will filter some portion of the noise out depending on how you adjust the phase. However, it is very easy to overcompensate and depending on your signal input, there are probably only one or two presets that really work.

Our phase was set to 5, and as it turns out, it was too low for our signal. When we overcompensated on our phase and set the level over 8, the inverse would occur on full motion video; blues would produce the same washed out static. The phase was left to 7 for the remainder of the analysis.

    LCD's look alright for 30"range but I am not a fan of LCD's for tv usage.

    Plasma's look MUCH better to my eyes for tv usage.

    The screen only running 1024x768 is pretty useless imo. Wasting all of that native screen resolution. Someone at the design should be shot! But good to get more lcd's on the market to drive the price down.

    Hey any reason why pc lcd's are not as bright or they don't have to be?

    I know my 12" Sony laptop lcd is bright enough at max for me. Same with my 23" monitor is very bright at max.

    Samsung Australia has a 0 dead pixel policy for their LCD's about 21" IIRC. I dont know about Samsung US.

    I am saving my pennies for a LCOS or DLP tv. Never liked lcds and never owned one. They still cant solve the dead pixel problem, which I find unacceptable.

    cant you use powerstrip or something to force a 1280x1024 image?
