Panel Type(s) Desired: Not sure? If it makes sense to get a smaller IPS monitor for my use case, that sounds good I guess? You would know better than me.
LED Backlight: Indifferent
Speakers: Avoided, but not too important either way.
Stand Functions: No preferences. Will probably just use as a normal monitor.
Additional Comments: Emphasis on image quality, I never play games. Must be new (I just can't bring myself to trust refurb /used). I spend pretty much my entire day in front of a computer monitor between my work and programming for fun, so I'm trying to avoid anything with defects that will annoy me over time. I've heard a lot of larger monitors tend to have gradients across the screen, this is definitely something that I'm trying to avoid as much as possible.
Thanks for any help! I've been searching for about a month now, and I really can't wait too much longer to buy one.
A 27 inch monitor with 1920x1080 has higher pixel pitch than most others, but that doesn't necessarily make it a bad choice.
As far as the three you list, I notice the HP 2710m and Samsung S27A350H only have 1-year warranties from the manufacturers, so you may want to purchase an extended warranty if you choose one of them. I advise against getting a monitor with an LED backlight, like the Samsung you listed, unless your desire for power efficiency or slim profile is strong enough to put up with the blue tinge that most LED-backlit monitors have.
