4K monitor - display two computers at the same time
I can't believe how difficult it is to find an answer.
I would like to buy a 4K monitor with the following use case...
But maybe I'm looking too much into this: I suppose I could simply buy a 4-monitor (2x2) desk mount and four 24" monitors (maybe 1200p or 1440p resolution to that extra bit of real estate), which might be significantly easier (and most likely cheaper) to manage. Thanks in advance. |
Basically what you are looking for is a 4K TV/monitor that supports split screens with multiple inputs. I know some older TVs do that but only for 2 HDMI inputs with side by side split screens. I don't remember ever seeing one that does 4 inputs and with 4 different screens. I think you are better off just getting 4 monitors with desk arms mount. I would just the 3 monitors with arms (those are more common and fit most desks. 2 for work, and 1 for home. And you can get a switch box, so for the weekends, you can do 3 monitors gaming LOL!

It's also 50% more expensive that the LG, but I'm really surprised there aren't more companies making this kind of monitor. My current office setup is two desks. One is an electric standing desk with a triple monitor mount, three 24" 1080p monitors, and used specifically with my work laptop. It's wonderful and productive. The other desk is a bleepshow mess with papers and computer parts all over the place, three desktop computers in various disrepair, and currently a single monitor that Baby Swede uses for her part-time online school. I'd like to clean up that desk, maybe move my triple monitor setup to that desk for two desktop computers (one of which will be dedicated to Baby Swede since I think online high school may become full-time), buy either a 4K monitor or quad monitor stand for the electric desk, and move one desktop computer over (while keeping my gaming computer on the other desk to avoid temptation). Still spit-balling ideas. |
It's a little bit of a niche area.
You'll likely want at least a 38" 4k monitor with this feature (PBP). More for traders/businesses who can afford this price. As you said, you want each to be at least 24", so if you put them in a 2x2 grid, the resulting diagonal is 48" (assuming same 16:9 aspect ratio) Display fusion on windows helps to manage large resolution (virtually split them) |
LG monitors can do this with their dual controller/picture in picture mode. I have an ultrawide -- 38" (sorry, can't remember the model) which I do use this periodically. It can display from any of its input side by side. TBH, I don't know really how useful it is due to the aspect ratio and readability as the laptop inputs are generally wide screen/etc.

The various hardware approaches here are one way to go, but if I'm understanding the OP correctly, RDP is a problem from the work laptop on vpn because
(the) laptop will be connected to my corporate VPN, so that is not feasible (and I don't want to expose an RDP port to the internet |

I would like these four equal parts to be the equivalent to four 21" monitors, but ideally four 24" monitors due to my ageing eyes. I for the life of me cannot figure out what size 4K monitors would be the close equivalent. For monitors, 49" ultrawide is a common size and usually does 5120x1440 resolution, and is roughly the same as 2x 27" QHD monitors next to each other. Countless Google searches talk about utilizing Remote Desktop to connect to my home computer to occupy the top half of monitor, but my laptop will be connected to my corporate VPN, so that is not feasible (and I don't want to expose an RDP port to the internet). I have no problems using two separate mice/keyboards for each computer, but I've been told that many 4K monitors now have built-in KVM switches. I also have an unopened Logitech multi-device mouse that can be used across different computers. Using one on remote desktop can work well, but there is also https://github.com/debauchee/barrier which is the free/open source replacement of the now-commercial Synchrony - which is KVM over IP, and works really well.

Don't see any particular advantage over the LG (although I've looked at the LG's specs for about 30 seconds total), and quite a bit pricier new - but it is frequently on sale via Dell Outlet ( https://outlet.us.dell.com/ ) for around the same $600

I get this if 100 percent of the network traffic on the work laptop goes through the VPN, but (almost?) every VPN client I've ever used lets you bypass local IP addresses, for example to connect to a local printer. Is there really no way to connect over the local LAN to the home desktop?

you'd do much better with just treating it as two 32:9 (3840x1080) widescreens on two cables
