I would assume this is a 27" or similar?  IMHO for larger than 24" you want better than Full HD so this should be ideal.

The majority of applications scale fine these days.  Some older applications don't scale nicely, but this won't be an issue for coding as you'll almost certainly be using a recent version.

I have a 24" that is 1200 tall and love it as I can have 1080p resolution work on screen plus see my taskbar down the bottom.  My second screen is a 29" ultrawide that is 1080 tall and is beautiful to use.

Had one on a 24" for a bit and was great, but if you suffer from only 20/20 vision or worse might be a problem. 27" is fine for everyone when I worked at a place with some of those.

Should be fine, most older programs pre 2010 won't be happy

It was fine. Set at 100%, not looking at what looks like things thru a stocking like 1080 at that size at 6-700mm does. I run games at 720 for FPS and that looked nicer on it than on a 1080 panel. When I can afford a real graphics card and screens will probably look at a 3 head 1440p setup. Till then just using horrid cheap ex lease 1080s and sitting miles back to not get annoyed.

The cheap 1080 HPs I have do that checkerboarding thing too, which is quite noticiable. Somethign to do with an 18 bit panel I was told.

gzt: Looking at 24s. A number of places have Dell QHD with DP at an excellent price.

My vision is ok.

Can you expand a bit on how you found 24 QHD in practice?

Personally, I think 24inch for that res is far too small especially for business, the lowest I would go is 27inch.

I run a 27" 1440p, and I'd say it's fairly comparable to 1900x1200 on a 24". I'd expect 1440p to be too small on a 24", unless you have exceptionally sharp eyesight. 

Some people i know ended up getting their staff bit 768p TVs because they couldnt deal with a 27" 1080 monitor. Old accounting software didnt scale well with turning up the scaling and changing res on the 1080 panels to 800x600 made them constantly pop up errors about a crap resolution.

One size does not fit all for displays despite what IT departments would love for.

I've got a 27" 2560x1440 as the main monitor and 24" 1920x1200 as the secondary.  I do a lot of work via TeamViewer so find it super handy to remote to a FHD screen and not have to scroll/resize.

Snapping windows to each half of the 27" also keeps them much more readable/usable.

1080p is OK for coding.

1440p is way better for coding in my opinion.

If you don't have large a IDE, or applications then 1080p is fine.

I have 3 x 27" at home 1440P for business and a dual screen 27" 1440P, I don't have too many issues. I have exceptional eyesight though.

I have a 27" 1440p in the middle of two 24" 1080p's and I love it. I'm often tempted to just go for a bigger widescreen but this setup works really well for me.

I'm using a Dell 25" 1440p right now. Changed from a 27" 1440p recently. I prefer the sharpness of the 25" vs. the size of 27.
