Albatron LWX-30-AMS: Albatron's Convergence LCD TV

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.
