text: my roomates extra screen has a red hue how do we change it back? its a hyundai imagequest l70s any bit will help it went from a yellow hue to a red hue with just truning it on. i think it has to do with a small powersurge we had but im not sure if thats it or not. it could be that the monitor is on it's way out.  that's usually one of the signs.  try checking your cables first.
