Thanks for the detailed explanation and picture!
I don't know much about monitor options. I did check Orion which I believe is a common CCTV monitor manufacturer and their products top out at 1080p.
I think the 5MP requirement is the tough one. I don't want to hijack this :) but I don't think the increase from 1080p to 5MP is going to make a real practice different for viewing a 5MP fisheye camera. Related: Testing 4K Monitors for Surveillance
I'm sad to say you're probably not going to find this. Most monitors above 1080p start at at least 24", usually closer to 27". Object size on screen is so small at these sizes that the extra resolution really won't do much for you. You'll just be squinting to make it out.
I'd recommend using 1080p monitors. You can get them from Marshall. Considering the fisheye cameras need to be dewarped to be in any way useful, 1080p seems like more than enough resolution. Do they just want to look at a warped fisheye 24/7?
If you do find a monitor small enough to work but it's not rack mount, you could also get a VESA rack mount like these from Middle Atlantic.
I think you may find what you are looking for at Orion. These guys make a real high quality monitor they call "Surveillance Grade". These are first class boxes (with of course a first class price). Couple of things i like about them: They restore to normal after power loss; much more robust, made from metal components; rated at a TRUE 50K hrs (your consumer grades will make this claim, but they assume a 10 hour daily on time); thinner bezels; inner plane swtiching; pixal shifting (eliminates image burn-in); non-relective glass ("Grade A"); and more set up options.
I put one of these things into and EOC, along with two consumer grade versions and the picture difference was really apparent. Of course at $3-4K a pop, the better be.
I have also used Marshal before. You may want to search "Broadcast Grade 1 monitors" or "studio monitors" . Again pricy, but you will probably find what you are looking for.
Let us know what you find out.
ViewZ monitors are basically the same as Orion.
And I agree, forget higher than 1080p resolution in a monitor smaller than maybe 40" (and even that requires very close viewing to see increased resolution).
Here's an experiment most people should be able to do at home that will prove my point: look at a high-quality image, say a "live" sports game on a (not huge) TV on ABC or Fox, then look at a sports game on NBC or CBS. Which has higher resolution? Can you even tell? Try the experiment with your eyes at different distances from the screen. Still hard to tell?
ABC and Fox broadcast in 720p while NBC and CBS broadcast in 1080i. Yes, you may see a bit of interlacing effects on NBC and CBS due to their interlaced images but I seriously defy you to tell any improvement in resolution. And remember, network TV is shot, recorded and broadcast using professional-grade equipment with far better video capabilities than most CCTV.
5MP cameras are unlikely to look any better on super-resolution monitors than on standard monitors unless:
- The monitor is really huge (at least larger than my 60").
- You're sitting far closer to the screen than your momma would allow.
Also, you can fit at least a 19" LCD monitor in a 19" rack, maybe even some 20". I've even "crammed" a 21" CRT monitor in a 19" rack - the screen fit but the outer bezel was partially obscured by the rails. Until we replaced our individual monitors with a monitor wall, we were using a mix of Orion and ViewZ 19RTC monitors with the manufacturers' rack mounts.
Have you already dismissed the discontinued 30" (diag), apple Cinema monitor, shown here?
They have the resolution, they are made out of aluminum, the back stand detaches easily, leaving a just a slab of solid monitor (external power supply). I have 2 of them still working after six years... They measure 27" x 21", so I don't know if you can get them in the rack somehow, (portrait?), but apparently you can still get them in the link above...

So basically, as I see it, the OP has a big decision to make: either limit monitor resolution to 720p if he wants monitor(s) that will fit within a rack or to 1080p if he wants monitor(s) that are rack-mountable but won't actually fit inside the rack or do away with the rack(s) and provide larger monitors with 4k (8MP) resolution.
I see no way around that decision.
