Anyone know how those 2 monitors compare?

LCD2190UXi
SA-SFT (S-IPS)
contrast ratio: 500:1
brightness: 250 cd/m2

LCD2490WUXi
H-IPS
contrast ratio: 800:1
brightness: 400 cd/m2

The LCD2190UXi is SA-SFT which is supposed to be a better version of S-IPS. Is it good enough to eliminate the purple hue on blacks issue? And it has a worse contrast ratio and brightness than the LCD2490WUXi - would that make a big difference?
 
The 2490 has a A-TW Polariser hich elimates the purple hue at off angle viewing. The brightness and contrast ratios don't mean a lot.

250cdm/2 is most likely going to be brighter than you want to run any monitor. I run mine at 120cd/m2 as any brighter starts to hurt my eyes. There is no standard way to measure contrast ratios so we cannot infer anything from them.

I would go for the 2490 as it has a larger resolution and is a fantastic monitor.
 
The 2190UXi uses NECs own IPS variant AFAIK. I think it does have less contrast, and slower response time, but I think it may have a native 10 or 12 bit panel.

I have never seen one so I have no idea what the off angle performance is like.
 
@mlewis A-TW polariser eliminates the white glow, not the purple hue :)

From these two I'd choose 2490.

The 2190 has the only subtle advantage over the 2490. While the 2490 has minimal "sparkling" effect of AG coating (LG panel), the 2190 has even less (NEC panel).
The 2490 is superior due to A-TW polarizer and wide screen.
Higher CR of the 2490 is useful for general use. If you focus on photo only - it's not an advantage.
The 2190 has the same sort of purple hue on solid black from diagonal view that older IPS have.
Both monitors have Standard color Gamut.
If the 2490 loses it's unique SG & A-TW panel in it's upcoming "updated" version, the 2190 seems to be the last high quality shelter where you can survive wide gamut pandemic.
But...
According to some reports, NEC is going to abandon(?) their own panels production.

Could you point out a link that talks about the updated version? I figured all the new models would be wide-gamut.

So even the 2190 is in danger.
 
How would you compare the 2090uxi to these two (2190 & 2490)?
I can find one in my country for 500euro's half the price of 2490..

Probably a sticky FAQ thread is needed :)
 
I just read that they took out the A-TW polarizer in the LCD2690WUXi2, apparently because some people preferred to have a white glow instead of the green and magenta effect in the corners. So I would have to assume they will do they same for the LCD2490WUXi2.

I would say the more likely reason is they took it out to save money. I have never heard of anyone preferring not to have the A-TW treatment on their IPS screen.
 
Snowdog, good to know that a monitor is definitely better with the A-TW polarizer than without it.

I also wonder why the LCD2090UXi has the A-TW, but the LCD2190UXi does not.
 
The 2490 and 2090 both use LG IPS screens and that treatment may actually be applied by LG.

The 2190 uses a slight different type of IPS screen that NEC builds themselves. It might be more difficult to get the A-TW treatment (It might not be setup in the NEC factory to do this). Also it may not be a necessary. I have never seen one of the NEC based IPS panels, it might have less white glow than a naked LG IPS screen.

I think they put the polarizer on 24" and 26" screens because the white glow is more troblesome on WS monitors than on more traditional 4:3 21".
 
Documentation is notoriously messed up on products. The 2490 definitely has a A-TW polarizer.

I think if you looked around more you find sources that say it does have it...
 
Many companies have notoriously low-quality description of their products.
It is like selling cars and not knowing if they run on petrol or diesel.
