Monitor that won't cause eye strain? need a recommendation

Hi,
I'm looking to buy a monitor to connect to my laptop (which has an HDMI exit).
The most important thing for me is that the monitor would not cause eye strain (or reduce the probability), I'm not sure on what monitor criterias have to do with it (panel type? led? brightness/contrast? refresh ratz?).

basically my main use would be office uses, such as reading a lot of word/PDF document, building websites, and some photoshop and a little movies (no gaming).

I'm not sure what size and resolution would be recommended, 19"? 22"? 23"?
on the one hand I understood that higher resolution makes the text sharper, so maybe it's good for less eyestrain, but on the other hand it makes the text smaller (but I guess I can zoom in most of the times), so I'm not sure about it.

It also needs to be fully adjustable (especially up and down).

my budget is pretty flexible as long as there is a good value for money.

Thanks!

 

Eyestrain is obviously lighting more than anything else. Also obviously, glossy monitors may cause you to squint more in various types of lighting, especially if your back is facing a light source.

The maximum you'll realistically be able to run with an HDMI port is 1920 x 1080, and in that case monitors from 22-27" are available - and really, none of these should present a problem for any eye in terms of pixel density.

The Dell Ultrasharp U2312HM is a $250 Full HD monitor that's pretty much a known quantity for quality. You'll need an HDMI -> DVI or Displayport cable.

 

IPS helps...a lot...better colour reproduction and viewing angles definitely diminish the eye strain.

Some options are listed here:

Keywords that I can think of

Pwm
Led, blue

f.lux it reduces eyestrain by changing color temp and brightness. Expecially late at night. Give it time to get used to it.

 

I bought a Eizo FS2333. It's an IPS non glare. I can use the whole day without having headaches like I've been having with my laptops.

 

unfortunately the Eizo monitors cost about twice in my country,
I understand that IPS monitors are better, but what about parameters like PWM usage? is it a known cause for eyestrain? seems to be very hard to find monitors that do not use it.
also, is LED better than fluorescent? i've read that the PWM problem is much more noticed in LED screens.
and also, does LED provide blue colors?

I've DL flux, it just seems to make everything more orange, it's pretty weird and sure my eyes like these color difference...

 

You want something with a high PWM frequency (my AOC's run at ~250 Hz from what I can figure and it doesn't bother me, but when I work for long periods of time, I can notice the flicker when I move my eyes quickly from and to the screen - I keep them at 75% brightness, it's usually worse the lower you go).

Higher PWM - less eyestrain, the rest is pretty much equal on today's monitors (adjustable brightness, color temp, etc.). Refresh rate itself doesn't matter for eyestrain.

good adjustability is surprisingly hard to find, the best I can recommend is the HP ZR2440W, it has good ergonomics, good IPS panels, 1920x1200 resolution, RGBLED backlight and a 410Hz PWM, which is near what Apple was using in their Thunderbolts last time I checked (460Hz I believe - the newer ones may be higher).

The Dell 2312HM is also good - great AH-IPS panel, good adjustability, high PWM frequency (cant find actual numbers though), and it's way cheaper...

 

Benq have pwm free models, you can probably look into those of you want to be in the really safe side. . They use va panels.

The point about white led is that the spectrum had a "blue peak", cough, excuse my noob terms, Google probably explain better xd. It is not something "proven" like the pwm issue. Some people swear wled strain their eyes more than ccfl or gb/rgb led. Ymmv.
