As a matter of fact, I've been through numerous websites with custom cabinet hinges in a search of how to actually mount the 8" monitor under the cabinet lid. I've yet to find a practical solution, although the "middle shelf in chest" idea is one I haven't come across before. That might be worth investigating. The probelm is that the mechanism would have to hold up the heavy 3/4" plywood lid and would have to provide a solid backing for the monitor. This is a touchscreen monitor and you have to be able to push it with your fingers without worrying about the whole works coming crashing down. I would like the monitor to be more or less verticle (with a slight angle) when the lid is raised. I might simply have the monitor on a seperate hinged platform under the lid and raise it up manually. Perhaps the monitor platform could serve to lock the lid into an open position. It would be neat to have the monitor automatically lift up into position as the lid is raised but I don't really think that's a workable idea. These things I'll have to figure out as the project progresses.
As for the resolution on the touchscreen, regular Windows screen characters do indeed get very choppy at the 600x800 resolution, often to the point of being unreadable. Luckily for me, however, this problem does not seem to carry over into the TouchTone software. The characters in this program appear very crisp, even with the touchscreen at the higher resolution. Since the monitor will be used to run the Touchtone software 99% of the time I don't see this as a big worry. Anyone thinking of buying this screen to run regular Windows software had better do some research first, however.
