"Agree with alidan, at this density, pixels are wasted: you don't see more as you need to scale everything up.
And, knowing the hardware you need to drive this resolution,, I don't see any interest except for some niches.
You need at least 44'' to exploit 4K. "
While true of a TV at normal viewing distance. This is complete and utter BS for a desktop monitor. My eyesight is not that great and i can easily see the pixels(if i look for them) on the 1920x1080 monitor im staring at as i type this.
The move to 3840 cant happen soon enough. If i had a spare 1,400 id be all over this monitor. But i dont, i have to wait till the price comes down. Also wait for the refresh rate to go up, 60 is too low.
185ppi will be hard to see unless you really try hard. But sub 100 its pretty easy to see the pixels. The desktop world has been stuck with 90-110ppi for FAR FAR too long.
