I went with a BenQ EW2740L 27" 1080p due to my failing eyesight. Going 1440p would have been a bad decision for me personally. I'd have more eyestrain trying to see text than I would on a 1080p, so it all depends on how young your eyes are, and how good your vision is right now.
I initially wanted an IPS panel, but went for the VA+ in the BenQ model, which features no backlight bleed and better blacks, two of the weaknesses of an IPS panel. I sit about 28" away from the screen, and I find the text easier to read than my old 23" TN panel.
I see you may have been at least the second poster to raise your points, but you help clarify it for me.
I once had perfect 20-20, and my near-vision was superb as well: In decent frosted-bulb reading light (maybe 60W bulb), I was able to read the entries unassisted in the two-volume compact OED, which came in a sturdy blue box with a drawer containing a Bausch&Lomb magnifier. Today, near-vision sucks, and I'm beginning to worry that I'll need a new prescription after only a year or two.
I also bought a replacement monitor -- a BenQ -- about two or three months ago. It became a trade-off of price and immediate need for me, so I picked the XL2420Z, probably wishing later that I'd bought the XL2720Z instead. "Gaming Monitor" is all over the promotions by both maker and reseller.
So I saved money with the price on my "stopgap" replacement; I deferred another $200 to $500 for a pending KVM replacement of my 20-year-old Belkin Omni-View, because this BenQ model comes with a little "S-switch" mouse-like device, which has replaced the limited analog-VGA "V" of my Belkin. Of course, the cabling -- if you don't have everything you need -- requires customizing your desired adapter output port and the BenQ connection, but it is extremely versatile.
But now you're saying that special accommodations for my eyes would be in order for a pleasant 4K experience, so I didn't waste money when my old 1080p crapped out.
Say! Lissen! Do you have the S-Switch with your model? I'd be interested in any tips for using the "Display-Pilot" SW along with the S-Switch and "Gamer 1 . . . Gamer 3" buttons to manage the sucker. But I haven't had to go through a complete "reconfiguration" through the S-Switch lately. It would be essentially the same with a new DVI or HDMI KVM, but the same setting applies to all connected computers, while the S-Switch is fine for individual tuning. For me -- it seems fine across the board. But I've uninstalled DP for all but one computer. I developed some minor misgivings for that.
Really, for the money and despite full-HD limitations, I'm coming to love this thing!
As I recall, this is a Taiwanese company. I would say they would be more mature in their promotion of "QC culture," or at least equal to their South Korean neighbors. The Chinese are improving. I wouldn't even know anymore of good Japanese monitors. NEC is still in bidnis . . . Panasonic? Does Sony make monitors? I'm sure they do.
