My friend just bought a monitor with the Trinitron tube, flat screen. He noticed that there are 2 faint horizontal lines running through his monitor so then he exchanged it for another. His new one is also has it though. So then right now I'm in comp class and they have the Dell flat screen monitors with trinitron and they also have 2 horizontal lines going across. I checked all the other monitors in the room and sure enough they have the lines. Are they supposed to be there? Kinda bugs me after a while.
