Don, if the monitors are on desks and simply wrapping around the users, then Sharp, Samsung, and NEC all have good solutions. If the monitors are always on, then you will want "professional" quality monitors that are rated for 24x7, otherwise you may have deal pixels etc after a relatively short period of time. Also, using 120hz or higher refresh rates make it easier on eyes.
If you want to build a wall, then you need narrow bezel monitors, which all of the above, plus companies like Planar have. Again, get 24x7 rated monitors.
If you are putting systems on desks, I would probably stay away from 4K for now. It really is best at distances of 10 feet or greater (unless you are a radiologist, geophysicist, etc) with a larger screen size (55-105"). 4K looks great, saves space and lets you display up to 8MP cameras at full, unscaled, resolution, and you can run PiP to put more than one system on the same monitor (we have systems for this that support up to 12 inputs). For desktop smaller screen sizes like 32-42" are probably best.
For a wall, you will need to decide if you want to treat it like one giant monitor with picture in a picture, of if you want a collection of independent monitors. If you want to treat the wall as one canvas, then you should get a display wall processor which provides video scaling, mullion compensation (bezel spacing), and management. If you don't need this, then 4 headed PCs with remote KVM sharing should be fine (use Synergy which is an open source solution).
Keep in mind if you want to remotely view streaming video using an IP remote desktop solution, technologies like RDP, VNC, and the like really do not handle fast refresh well. If all you want to do is remotely control a system, then they are fine. For full motion video you need something like RGB Spectrums VDA.
RGB Spectrum has complete solutions for video system integration that scale from small multiviewers (4 video signals onto one monitor) up with complete shared user control, arbitration, HDCP (encryption of video signals) and the ability to drive display walls of up to 56 monitors from over 100 input signals, controlled by an infinite number of users. These are advanced systems used by NASA, the military, utilities, oil companies, etc.
For remote control of full motion video, we have a lossless video oriented IP KVM solution we call VDA. It moves video at 1080p60, 4 monitors at a time. Requires about 10Mbps per video channel. It is a hardware thin client system and renders video at local quality with very low latency and with synchronized mouse. It is a point to point system, meaning that only one person at a time can control a remote system and there is no arbitration of users (first in gets control) unless it is used with our more advanced MCMS control room management system.
I would be happy to answer your questions and point you in the right direction, depending on your needs.
