How do you handle long runs? Say, 100ft from machine room to amp, followed by a 50 ft run to the screen?
If I understand this correctly it should not be a problem. If you want to "uniquely" control the playback on each monitor then setup a server and rip the files to a server and setup a share. Then setup 10 WD devices (one for each monitor) to access that share. You will need to run cat6 to each WD and HDMI out from each WD to the monitor. If you have to make long runs use a HDMI to Cat6 device from WD to monitor.
Now if you want to setup certain monitor to always play the same content at the same time, make a slight change. Identify monitor groups and purchase that number of WD devices. Then run cat6 to WD devices and HDMI out to a HDMI splitter amplifiers. From the splitter run cat6 to monitor (assuming a long run) with an Cat6 HDMI adapter on the end to connect to the monitor.
One last option would be to get an HDMI cat6 to HDMI Matrix
switch. For this you will also create groups and buy the same number of WD devices. Except this time run cat6 to WD and HDMI out on WD to matrix switch. Then run cat6 from Matrix switch to all the monitors. With a matrix switch you can have all monitor display a single inpute (one WD box) or you can have any number of the boxes display the WD content. The limitation is the number of WD boxes. My only concern with this approach is that Matrix switches can sometimes be finicky. But you buy all the exact same monitors and go with a rock solid Matrix switch this option would give you the most flexibility.
You also may want to get a fancy remote system to uniquely control all the boxes and/or switches.
