At work we have 8 LCD TVs mounted with only a power and coaxial cable drop behind them. The coax for the displays terminates in our server room where it's all just hanging there not connected anything.
Currently I'm running a small form factor PC behind each TV to power each display and show our digital signage. The PCs are connected to our network via wifi and plugged into the TV with an HDMI cable.
What I'd ideally like to accomplish is to remove the PCs behind each display, replace them with one PC in the server room and output it's display over the coaxial cable. I have vga, display port, hdmi and DVI outputs available. Sound would be preferred (but not necessary), so I guess I'd be looking for hdmi or display port to coaxial, and I'd assume I would need some sort of amplifier to split the signal across the 4 displays.
Is what I want to accomplish possible? If I can convert my PC signal to coax is the quality going to be good enough? We have a fair amount of small text that needs to be legible.
I've seen some systems that seem like they *might* do what I need for a few thousand bucks, spending maybe $500 or so is more where I'd like to be.
