question about DP1110

[Linkin Park]

Hi, recently i bought a DP1110 off of ebay and i got it and i noticed there are two horizontal lines(really small but noticable on a white background) on the screen each 2/3rds away from the top and bottom. My question is that normal and is the aperature grill or is the monitor broken?

Monitors using a trinitron tube have 2 wires at approx 1/4 of the way in from both the top and the bottom, the Dell P1110 uses the trinitron tube, so yep. Perfectly normal.

Another Question i just realized a couple minutes ago. When i listen to a song that has a lot of bass in it i notice that the sides of the monitor sort of dim a little from the bass. is this normal or from a loose wire or something
