Had to move the 1920x1200 to the work laptop, so I pulled out the LG 2560x1080 for the personal laptop -- this thing is nice! It's the little little brother of the "I'm done with 4K" ultrawide monitor (the regular little brother is the 34UM65, which is 2560x1080 @ 34", whereas mine is 2560x1080 @ 29"), the pixel pitch must be pretty damn high. I'll definitely be lusting after the 34UM65 for a while.
...with a caveat -- laptops usually only have one of certain ports (HDMI, DisplayPort), so maybe for a laptop "extension" screen -- one big one. Unless one very carefully selects one with a very capable docking station.
