Question about quality of the Korean 1440 IPS or PLS monitors (can anyone who owns one vouch?)

post #1 of 4
Thread Starter 
So I've been looking into the low priced IPS Korean monitors and at first I thought it was too good to be true to get a great panel like the LM270WQ1, LM270WQ2, or Samsung PLS at a reasonable price. The more digging I've been doing, things looked like this might be a viable solution for me until I got a comment on one of my posts by one of the admins over at TFTcentral. He said:

"I've not tested the Crossover or Qnix, but i have tested the QH270-IPSMS monitor, albeit not posted a full review yet. One thing i'd advise you check on those models is whether the brightness control actually offers you a proper backlight control or not? On the QH270-IPSMS it doesnt control the backlight, rather it changes the digital white level. so it reduces the luminance of the screen but BADLY crushes the contrast ratio if you move it away from its default, overly bright setting! It's a worrying thing ive seen on quite a few of these korean models, and i'm testing the Achieva Shimian 27" Zero-G at the moment which is the same!

If the other two are the same, i'd probably advise to stay away from them all to be honest. It's a stupid way of changing the screen brightness and should never be used in my opinion."

Now here's my question I'm not sure if all of the Korean monitors have this weird brightness control. Can anyone confirm any Korean IPS or PLS monitors that don't use this crazy method to control brightness?

Thanks in advanced for taking the time to respond to this smile.gif

I have a QNIX QX2710 and changing the brightness definitely does not affect the contrast ratio.

It's mostly the multi-input models that have that problem. All the single-input models without an OSD have proper backlight control.

My CrossOver 2720MDP has proper back-light control, the contrast stays around 850-950:1, though I have not set the brightness lower than 120cdm/2. The contrast drops to 850-ish once calibrated vs. 900-950 when not calibrated.
