When it comes to a monitor, higher resolution is better, right?
Not for me. Tried using a 27 inch 4k monitor (3840x2160) for my main monitor today, and was very disapointed.
This was replacing a 27 inch monitor running at 2560x1440 that I was very happy with at 2560x1440 -- lots of real estate on the screen, but text large enough that I could read it.
At 3840x2160, the normal text size in windows is too small to read. So the solution would require changing desktop scaling in windows -- which would be ok except in a multimonitor setup that can cause issues when you have one monitor with higher scaling than another.
The high resolution also seemed to strain the abilities of full screen apps.
And the brightness of the new ($500) monitor left much to be desired; far inferior to my 2560x1440 one.
And lastly, trying to set the resolution of this 4k monitor back down to my previous 2560x1440 resulted in a very blurry display, so that isn't an option.
I'm returning it -- just thought I'd post a word of caution to anyone considering the move to a 4k monitor -- unless you have a really serious reason to need 4k, and you've sat down in front of one to confirm you like what you see, I would reconsider whether you really want one.
If you only have a single monitor, or plan to run multiple monitors ALL at 4k, and have the spare horsepower, and have the money to get very high quality 4k bright monitors, then 4k may still be for you.
