Has anyone had experience with a monitor larger than 40" on their desktop?  
Currently Dell has a 27" USB-C monitor for $422 and a 32" monitor for $594 
while Kogan has a 43" for $799 and I'm thinking of what to buy in July.

My wife's monitor broke and my plan is to buy myself a new monitor and give 
her my Samsung 28" 4K monitor (which is higher spec than her previous 

USB-C monitors are ones that can supply USB-C power to a laptop while also 
having keyboard and mouse connected to the monitor as a USB hub.  It's 
basically all the functionality of what used to be a laptop docking-station in 
a monitor with a single cable.  It would be quite handy to have that 
functionality as a laptop with USB-C is on my shopping list too.


According to the above article you want a TV to take up 30 degrees of vision, 
but for a monitor it's probably a lot more as you focus on the window that 
needs your attention.  Based on resolution and size according to that article 
a 43" 4K "TV" would be best at a distance of 80-160cm with the minimum being 
based on not seeing individual pixels.  For a monitor you don't need to not 
see pixels IMHO, just need to have enough of them to clearly represent 
letters.  So maybe 43" would be a good size.  It seems like a lot, but when I 
had a 17" monitor on my desk any larger than that seemed excessive...

Another possibility is getting multiple monitors.  For a long time I have been 
unconvinced of the benefits of multiple monitors, but now I'm working at a 
company where there's a USB-C dock at every desk with 2 monitors and I've got 
used to working with 2 monitors in addition to a laptop display.  If I bought 
2 of those 27" USB-C monitors I could have them both on my desktop system most 
of the time and connect one to a laptop on occasion when I needed to.  Linux 
has really good support for dynamic plugging of monitors nowadays and 2*27" 
gives me twice the pixels and 3/4 the area of a 32" monitor for about the same
