Monitor flickers with lines across screen

screen is going bad which is why its flickering and has the lines across the screen. Theres a board behind the lcd and when that doesn't process the voltage properly it can cause the screen to flicker. White lines across the screen means the screen is going bad. At this point unless your monitor is under warranty, go ahead and replace it.

Connect the monitor to a different computer (laptop or desktop), to see if the problem "follows" the monitor.

Connect a different monitor to your computer, to see if the video-card in your computer is generating the "wavy" display.

Move any "power-bars" and PC Speakers *FAR* away from the monitor, to eliminate electrical interference.

LG L1900E flickering after cold start

This is probably due to a bad solder joint somewhere. Bad solder joints can effect a unit in the reverse also. IE works at first and then dies after it gets warm. Think about how metal expands when it is heated. And contracts as it gets cold. If there is a hairline fracture on one or more component joints, this would cause it to not have such a great or solid connection when it is cool, or contracted. As it gets warmer, the solder expands therefore filling the void and giving it a good connection.

Regardless, it will likely only get worse over time. If you're handy with a soldering iron, pop it open and reflow all the joints. Especially the ones on the transformers and copper coils. Best to hit them all, excluding the tiny surface mount devices.

Wavy lines, goes black during video games.

It sounds to me like the monitor's refresh rate is too low to support your current settings, and the demands of the game. Have you tried adjusting the refresh rate? If I'm right, you should be able to fix the wavy lines that way. I'm not sure how much control over the refresh rate the game takes, but if you can fix the wavy lines and the game still doesn't work, I think you're not likely to get the game to work on this monitor.
