There are a buncha korean monitors in the 260-330 price range the 27" 2560x1440 IPS screens. On the other hand you can get a benq 27" GW2765HT for 400. Obvious benefit of the benq is a 3 year warranty and sold by newegg and not a third party seller. The Benq has a zero flicker backlight and low blue light reading mode and also has height, pivot, tilt stand adjustments. Korean monitors have none of this. Also poorer menu system and less inputs on the korean monitors.
Other than all the side benefits of these auxiliary features are the korean monitors as good at displaying images and video?
BenQ is apparently a Taiwanese company. It could even be the case that they have manufacturing facilities in S. Korea.
Here's an off-the-top-of-my-head generalization. I believe that what had originally been a Japanese Quality-Circles/Quality-Control culture eventually spread to SK and Taiwan. It may be that this development is also occurring in China, Indonesia and other places.
Samsung, I thought, was a S. Korean outfit. There is another make of monitors called AOC, often described as "Admiral of Korea." [If you don't remember, Admiral was once an American TV manufacturer.] I've heard worse things about AOC, even though I merely considered buying one.
The monitors that cost less -- among which you'll find some Sammys and even Viewsonics and NECs -- likely have more modest specs, fewer connection options and so on. They won't so easily have the BenQ "S-Switch" feature.
You could even laugh at me, even as I'm trying to "negotiate" my way into the 4K realm -- only in the "planning" stages now. But my Hanns-G monitor, which was a piece of crap, "went south" and "took a dump" around January.
So I was faced with a choice, and budgetary constraints. I finally decided to shell out for the BenQ XL2420Z "full-HD" gaming monitor. Only 24", only full-HD, but I'm truly impressed, except for the fact that you won't like the default setting right-out-of-the-box.
It requires some adjustment. But it lets you store three gaming profiles, the S-Switch makes changing OSD-mode display changes easy -- to include switching among multiple computers connected to the same monitor. [The "V" part of KVM switching].
Folks remarked that they thought the $320-$330 pricetag for the XL2420Z was excessive. Even for an "interim" solution, I'm glad I bought it.
There are plenty of decent full-HD monitors in the $100 to $250 range. But they do not likely have 1ms response time, downloadable game profiles, built-in "Game," "Movie" etc. modes, 144 Hz refresh rate as desired, or DP-plus-DVI-plus 2x HDMI-plus-VGA connectivity.
And surely, you can find good 27" desktop monitors. I could almost wish I'd picked up the XL2730Z or something like it. In some respects, you get what you pay for. And if you don't want to pay a lot, there are some inexpensive units that should prove quite reliable, nevertheless.
