How many monitors do you have?

I have two ACER monitors. For most jobs, one is fine, but I feel like if you develop/code, two is needed since you can put code on one, and documentation/resources on the other

i have Dell UltraSharp 2209WA black, 22". its very old monitor. I am already thinking about buying a new one

2 monitors and my laptop screen
monitors are actually 2 tv's of each around 42 inch.
laptop screen is 15.6 inch

Two 24 inches. Two monitors was the best decision of my life I get so much done because of it.

I only use 1 monitor and it works fine for me. It depends what you need to do though.

I used to have three monitors but honestly two is the sweet spot. Anything more (in most cases) is more convenience than necessity.

Just a single 24 inch unit from AOC for my PC. And a different one for TV (Sony Bravia LED, 32 Inch).

2... because with one I couldn't Task Manager games when they hard crashed.

2x 24 inch monitors both from Samsung. Hoping to get a third pretty soon...
