I have a 25" WG K257193 that looks very good color and brightness wise. However, I have what I can only describe as horizontal waves moving from bottom to the top of the screen that don't seem to stop regardless of how long the monitor has been powered up. Its the same sort of a wavy pattern water would make to try and describe it a bit more. It doesn't impede game play in any way and when there is a bunch of motion on the screen it is barley noticeable. It is when you are looking at a still screen, such as the street fighter character select screen, that you can REALLY notice it. Either way, I do plan on doing a recap and replacing the filter cap as well. Beside doing that though I wanted to make sure there wasn't something else I should be checking in the meantime that may be causing this effect?
