I just bought this display from Newegg. I've found this forum incredibly helpful, so I want to share my experience with this monitor with you for anyone that is looking for an affordable 23-24" IPS screen. I haven't found any mention of this here, so I figured it deserved a new topic.

Short version: you probably want to stay away.

I posted my (very) negative feedback on Newegg already, but since then I've found this video which shows the horrible purple glow I'm experiencing with this monitor. I'm sitting about 2.5 to 3 feet from the screen, and regardless of angles the glow dominates the corners (mostly the bottom corners when looking straight on). I'm running at 66% brightness, but the brightness level doesn't make any difference. I don't have a calibrator, but I've fiddled with the OSD colors to get white to look as 'white' as possible to my eye. It wouldn't be so bad if the glow was white, but purple is just so much worse and more distracting.

I bought this for a general purpose/casual gaming monitor, and the glow destroys dark scenes in movies and games. I'm a huge Mass Effect fan, and all I can see walking around the Normandy is the damn purple corners.

What good I can say about it is that the response time is fine for casual gaming (little blurry, but it doesn't greatly detract from the experience). The AG coating isn't as aggressive as it is on my 17" XPS laptop, but it is noticeable. The color and viewing angles for non-dark stuff doesn't suffer horribly from the purple-shift, but it is noticeable. I also don't notice any backlight flickering at lower brightness.

I wonder if Newegg would take it back without a restocking fee. I'd be willing to spend $400+ if I was confident I'd be getting a great display, but I'll probably not roll the dice on a Korean import or something with horrible BLB reputation without a seller guarantee (Otherwise I might as well just stick with this). Any suggestions for a 23/24" replacement?
 
This is sort of a two part problem and it's hard to say if the corners are "flashlighting" because of the edge lit LED backlight as the video wasn't of a completely black screen. It looks like the bottom right corner is flashlighting in the video but not the rest. IPS panels transition to "purple" though when you start shifting your viewing angle. There are some that go white but I think a majority of them are purple. However, there is something "off" about the way that video is doing it at least compared to a S-IPS panel.

I came across this monitor the other night when I was messing around online and was turned off from the input lag and pixel response time. There were also multiple complaints about backlight bleed on them.


When it comes to a 23" e-IPS screen (and yes everyone hates the price) the Dell U2312HM is what I would recommend based on reviews of the pixel response time, input lag, etc. Plus you can exchange it as much as you need to via free overnight (at least I believe it's 1 day but it may be 2) cross-shipping until you are satisfied with the panel. That's assuming you want a 1920x1080 23" e-IPS domestic model for around $250 give or take. If you want to take a chance, then the Korean 2560x1440 monitors are probably by far the best purchase in the $350 range provided you want the resolution, an IPS panel, and don't care about the 60Hz refresh rate. It really just depends on what you want/need versus what you are willing to spend.
 
There's zero BLB on my model. It comes from the purple glow, which may be what people are mistaking for bleed. The response time is also 6ms gtg I believe. There is a reasonably good review of the monitor here, but he makes no mention of the glow, which is unfortunate because it really dominates the corners of a dark screen.

For the u2312hm, would I be expecting glow as well? My understanding is that they are very similar if not identical panels. That's why I picked the Viewsonic since I figured it's otherwise the same just with less bell and whistles. Are there any videos I can check out? I have a 3.6MB video of my screen with a black background demonstrating the glow. Maybe I'll put it on Youtube. Honestly were it not for the glow this monitor would be amazing (for the money). Maybe I'll try to get used to it :(

Honestly I'd rather buy something domestically, that way I can send it to someone if it dies on me after the 14 days the Korean sellers give you. For 350 though...
I see people saying good things about the S27A850T around here, but I see no mention of a 24" version (on google either). I can't even use 2560x1440 until I buy an Ivy Bridge machine, so maybe I'll play the Korean lottery then

Man, picking a monitor was so much easier when I just stuck with whatever shitty TN panel my laptop manufacturer stuck me with :p
 
With one exception, all the IPS models have it. There's nothing to gain in looking for alternatives - just place the monitor further away.
 
The ViewSonic has the same panel as the U2311H, not the U2312HM. The U2312HM glows silvery white instead of purple. The intensity is about the same though, so you'll still see it in the corners, but it won't be purple at least.

Most current IPS panels glow silvery white. Older panels were orange/purple. I'm not sure why they brought back the orange/purple for that particular panel.
 
You can't ever trust the response time the manufacturer lists in the specifications or marketing material as they all measure it differently and will use the lowest number than get even if it's just on a single colour to colour transition. The AOC 23" IPS monitor, the Viewsonic, and there is a third, were all around 14ms on their response time when they were independently tested. TFT Central and PRAD usually have reputable response time tests and PRAD is where you want to go to look at valid input lag test results.


You're going to get a glow on any IPS panel when you change your viewing angle. It's similar to the loss of contrast/gamma that you get on a VA panel and how images go photo negative on a TN panel from viewing angle shifts. The difference with an IPS panel is that you don't typically see the shift from just looking at the monitor especially on something small like a 23". Viewing distance will play a role in how soon you see the shift though regardless of the panel type.

I can see people mistaking it for backlight bleed though because, people make the same mistake about everything outside of the viewing cone on a VA panel. A lot of people don't understand that backlight bleed isn't quite the same thing as flashlighhting and that flashlighting doesn't go away from a viewing angle shift so they never bother to change their viewing angle to see if something is truly flashlighting.

Identical panels do not equate to anything though because there are variances that happen during panel production along with the different hardware that are found in different makes/models as well as the differing firmware. (e.g. The VR-3225, 32LK450, and several other TVs have all used the same A-MVA panel from AUO at some point in their lifespan but the I/PQ can differ drastically between all of them.)

If you think buying a monitor is difficult though, try shopping for a TV lol. I agree though, it used to be a lot easier but, there also used to be a lot less marketing hype and blatant deception/lying/misleading than there currently is.

The U2312HM is LED as well, as is this Viewsonic but judging from TFTCentral review it glows silver. Some people prefer silver because it doesn't change the "color of black". I prefer whatever shows up less.

Is there a point where it does NOT glow? How far back do you have to view it while centred before the glow goes away? Most IPS panels I've used lose the glow when viewed with my head near the centre of the screen from about 2 - 3 feet.

This *may* be a new variant, or another cheaper variant thus the extra prominent glow.

The only panel I've seen that does not glow silver is the Dell ST2220T which is glossy, 21.5" and uses what appears to be a "S-IPS II" panel because it has >>> style pixels and not ||| like H-IPS/eIPS panels. It glows a dark blue.
 
Are you really set on having an ips panel? There are color calibration reviews showing that the higher quality tn panels display colors just as well, without the problems your experiencing check out benq gaming models for instance, great response time blacks are highlighted well but not so much it is not black etc, probly will be my next monitor
 
Really helpful all around, thanks!

I got out a tape measure to figure out the relevant distances. I typically sit 30" from the screen, and the glow is very apparent even when I angle it just right. The glow doesn't go away until 42"+, which is way too far.

I'm not totally set on an IPS panel; this model and the u2312hm for example just seemed like the best balance of CQ and a response time for my money and usage. Maybe I'll just stick with it if the glow is such a widespread issue, and going to the Dell with a more preferable silver glow would cost an extra $60 plus the cost of shipping this one back.

What kind of experience could I expect from say, an ASUS VH238H or similar panels? I don't really trust all the perfect ratings on Newegg for the cheaper TN panels, since I tend to be quite a bit more picky than most people.
 
higher quality tn panels display colors just as well,

Do you think Apple would use TN for their ipad?

A washed out image with black crush in dark scenes due to viewing angle deficit. No, you aren't picky. Picky is when you notice that the family has slightly adjusted the colour balance setting on the TV while you were away.

It depends on your pickiness. Everyone is different. A TN panel will show almost all colors changing from different vertical angles whereas IPS will show none or less. TN panels also can have white glow on black it's just possibly a little less obvious because generally the whole panel will glow, not just the corners first, and it isn't as strong until angles get a bit more extreme.

One thing about that "best gaming monitor" review: The picture with puss-in-boots shows purple corner glow, but the one directly after does not and he/she says there is no back-light bleed. I find that strange.

Edit: The writer mentions at the end of that review that purple glow from the corners is back-light bleed and that the monitor is defective and should be replaced.

It's probably related to the camera distance/angle and how the Puss n Boots still shot's increased lighting alters what the camera "sees".

The editor's note at the end likely refers to the people that wind up with panels that are actually flashlighting and not doing the IPS glow as a result of the viewing angle. In the comments section, they did point out that the glow on their test unit wasn't as severe as some of the youtube videos. However, people on youtube are really bad with camera settings and so the issue the youtube member is trying to show often appears exacerbated in videos. The same holds true for "user reviews" as everything in the world gets classified as backlight bleed when it may not be. (e.g. stuff outside of the viewing cone on a VA panel because it's lighter/brighter).
 
Do you think Apple would use TN for their ipad?
of course not, the ipad isnt designed for fast response time or input lag etc. if you placed a TN panel that had the same resolution as the ipad and upped the brightness to match the ipad display then placed a color spectrum on both, they would both display similar colors

some colors are slightly different but most of it is brightness or gamma related all of which can be adjusted
