21.5 - 27 - 21.5 PLP?

There are lots of threads by people looking to create a good PLP (portrait-landscape-portrait) setup. But best I can tell there's no ideal solution.

The setup I see most often is 20-30-20: A center 2560x1600 30" display, flanked by two 1600x1200 20" displays. Pixel density is almost identical (100.63 vs 100 ppi) and the resolutions match as well. Drawback is price. 30" displays are expensive $1200+ retail (Korean ebay deals aside), and the 20" displays are too - the classic Dell 2007WFP is north of $400, and you may not even get an IPS panel. LG has a display that should work for just under $400. Total cost for the setup is likely to be $2000 or more. Maybe a bit less if you go with used gear.

Prices on 27" 2560x1440 displays have really come down: the Korean ebay specials, The Dell 2713HM for $650 at Costco, and Microcenter/Monoprice offerings. This is arguably the real sweet spot for monitors in 2013.

Problem for PLP is that there are no good panels that match both the resolution and the pixel density. The closest are 15.4" 1440x900 laptop panels, which require a hacked together interface. Even then, the horizontal resolution of 900 pixels is not enough to view many web pages.

What about abandoning the need to match the vertical resolution on the 27" and just matching the PPI? If you do that, you can pick up 21.5" 1920x1080 displays (102.46 PPI, very close to the 27" PPI of 108.79). IPS panels in this size are readily available and cheap. $150 (Acer) or $220 (Dell, if you insist on matching brand logos and/or want a rotating stand instead of wall mounts)

Total cost for this setup depends on which screens you buy, but even if you go all-Dell it's only $1090: $220x2 for the 21.5" displays, plus $650 for the 27". Could be as cheap as $650 all-in or so if you go with a Korean ebay 27" and the Acer portrait displays.

Total screen real estate is also very similar to the 20-30-20 setup: about 7.8 MP vs 7.9.

The disadvantage, of course, is that your portrait displays are physically taller than your center display. Like this:

For some people, this is likely an immediate dealbreaker. But I'm considering trying it. The economics are pretty compelling, and you end up with three very nice, new, modern panels. I don't see an obvious reason why productivity would suffer. Think of the vertical space on the portrait displays above and below the center display as a bonus. But I don't have any experience with PLP, just standard dual/triple LLL setups. So maybe I'm missing something.

I wish there were a better solution, like a 1440x1080 4:3 17" panel for perfect PLP, or 1920x1440 4:3 IPS panels of the right size for an LLL config. But those don't exist.

I know this is probably crazy talk, but what about paring a 1920x1200 with two square 1600x1200's?
 
Interesting. That would put all three panels in landscape, but would be narrower than a 16:9 LLL setup. Since they're all landscape, Eyefinity would work.

But to match the pixel density of a 1920x1200 24" IPS panel, you'd need a 21" 1600x1200 screen. The 20" 2007FP is close, but probably not close enough, and in any case is more expensive than the center panel (U2412M is $320, 2007FP is $350 for an older CCFL panel). It'd be cheaper to do an LLL with 3x 24" screens, and you'd have more screen to work with. Even if you, like me, don't value that extreme right and left real estate very much, it's worth something. This would only make sense if you could find cheap 20" 4:3 panels or if you had a very restricted space.

I don't think there are any 21" 1600x1200 panels, at least other than this $1300k professional EZIO panel.

Is there another physical size combo other than 24"+21" that works and is in production?
 
Another possibility is this 25" Acer 1920x1080 panel paired with 2 1280x1028 19" panels, in a combined 16:9 / 4:3 LLL setup like you suggest. Neither the pixel density or the resolution are perfect matches but it's pretty close.

Poor man's Eyefinity? With these 19" panels, total cost is only $505. Pixel density is relatively poor at around 86-88 ppi, but it's still a lot of screen real estate. You do have to give up on IPS panels in this range.
 
The lack of support for PLP in games made me give up my 20-30-20 PLP setup in favor of a 3x30" LLL. If you aren't playing with Eyefinity/nVSurround then matching PPI is better then matching screen heights as you are no longer treating the monitors as a SLS. The 20" 1680x1050 is a close match in PPI to 30" monitors and are cheaper than 20" 4:3 monitors (if you can find them). For a 27" 2560x1440 the closest PPI match is a 20" 1920x1080, which is a pretty rare beast. The virtue of the 20" 1080p monitor is that in portrait mode it is wide enough for most websites so it is more appealing for PLP use.

I agree - 1080 vertical resolution is a minimum for the portrait displays. But I don't know of a 20" 1080p panel. The PPI mismatch on the common 21.5 panels is not much worse (about 102 PPI for 21.5", 110 for a hypothetical 20", compared to about 108 for the 27"). That's what I describe in the OP, and I'm leaning in that direction.'

Ordered the Monoprice 27" IPS today. Will look into some 21.5" displays after it arrives.

The difference between 102ppi and 108ppi is pretty noticeable to me, I can`t speak for you but I personally would go for the 20in even if you have to go used. I`ve been playing with 6- and 7-monitor setups and even small PPI differences can drive me crazy.

I've got no objection to used. But I can't find a 20" 1920x1080 display anywhere. Anyone know of one?
 
Not very common at all - I've only seen the Hanspree (and I don't trust that particular manufacturer).

I've have 19" 1440x900 monitors in my array as "sidebar" space where they work great for progress meters, download managers, playlists, chat apps, volume mixer, email inbox list, simple text files,etc. It's nice having stuff on the sidebars instead of minimizing or cluttering up the main display. It's also handy for using fullscreen photoshop while having a few sidebar areas for file browsing windows, settings popups, dragging toolbox to them, etc. Can also keep an ftp browser open. Lots of uses that don't require a ton of width.

Note that I keep the 19" set back very slightly on ergo arms from monoprice which essentially shrinks them from my perspective so that they align with the main monitor(s) and the ppi looks the same. There is TN shift on the 19" ers but not bad with them angled towards my "home" seating position(s) and considering everything I use them for is usually textual ~ chat, readouts, prog meters, lists.

Btw that glare is the camera flash. There are no light sources 'behind" the monitor faces during usage.

Another early picture of roughly testing the original setup. The camera has a slightly fisheyed effect which makes the monitors look less aligned. They align more to my eyes and in seated position, including the side bezels appearing tucked behind the main monitor's pretty cleanly.

I really have no problem with larger sized monitors on the sides (like big ears) instead either, but I don't think I'd like the ppi appearing different so it would have to be a close ppi where I could set the monitors back to match ppi as I did with the 19" vs my main desktop display's 27" 2560x1440 108.8ppi.

Took the plunge. Haven't used it long but I like it so far. Mostly I have not been doing PLP, but rather PLL - one side display for in landscape for video/email and one in portrait for doc editing/web browsing.

Slight difference in pixel density doesn't bug me.
