FWIW, I've got the display issue fixed, apparently. Just the same, though, the monitor does not show up as a touchscreen device no matter what I do. I tried the aforementioned eGalax drivers, along with the TouchWiz 5.01.1.5310 drivers, and nothing. All the references I've seen here refer to screens that have been disassembled, while mine has not. Unless someone has a magic suggestion, I guess I'll box this back up, send it back, and hope the replacement works correctly.
