If it might help, I forgot to mention about the brightness of the TV when it is working right. Let say that picture I posted in the beginning of the thread, it would be much brighter and no green or other bright pixel dots would be visible and it would be a perfect image as well as brightness being bright. When displaying white background, It would be bright enough to keep the room lit up a bit. But right now it is not bright at all, it looks like a dimmed white (only when full screen). Also when it isn't full screen, it becomes brighter the smaller it is. So if I move my mouse from the computer screen to that TV, it is while and bright, but if I have the TV on a white background, it would be dimmed. So it seems the more colours it puts out, the less brightness it has and the darker the colours, the more brightness it has. Also the more colour it has too, it shows weird brighten pixels here and there as well, depending on the image shown. I hope this info helps out a bit to target what would cause it to do all this.
