Probably not appropriate for you, but I used to have 4 monitors running from my desktop.
Weighing up the power usage of the 4 little aged darlings, mostly Dell, I noticed Kogan had a 4K UHD 58 inch smarter TV for about $900, so I bought it.
It connects to computer with HDMI.
The running cost is about half I think but it's tax deductible.
I do house plans, and need a system with grunt for my graphics.
So during the day I can have say 4 or 5 programs running and they are all readable at a glance without having to zoom in all the time.
My drawing program, Prorealtime (8 graphs), Commsec on browser, file manager, big clock, Thunderbird email, Excel timesheet, etc

I probably spend about 10 hours a day looking at it.
My daughter tells me it's a bit bright, but I like it.
