Have you thought about making some trim to go on the outside frame of the LCD? Something like corner bead you can buy in a store?
Side note: I work at an airport which has some old hangers that are being demolished. All wood construction, some of the beams have to be 8" x 36" BC fir. Don't know why, but it pains me to see them being ripped down without a thought being put into salvaging anything. I see diver's that are bring up old logs from the bottom of rivers, why can't the salvage this stuff makes me shake my head.
