EW2440L

I have just purchased this monitor (EW2440L). Colors are great and it's practically flicker-free. Thin bezel is just a marketing as you still have about 5mm black, non-displayed area on the top and left/right sides. On the bottom it's perfectly fine.

Unfortunately my first experience with this display is not good. The Low Blue Light function is basically something that you could adjust yourself manually using RGB settings. It just pulls blue down making everything look "redish". Similar to f.lux effect. Not sure if watching everything overly red makes it easier on eyes.

Most of the lagom tests went fine except the gamma calibration, which would not pass unless I disabled low blue light features and put the brightness/contrast up to values, that would simply kill my eyes in no time), as well as sharpness test. No matter what sharpness setting I use on EW2440L it's never passing the test. Not even that. You can actually see the text slightly blurred (if sharpness set to minimum) or overprocessed and actually bad looking (if you go too high). After using it for a whole day I have actually gotten more eye strain than on any of my old 5:4 CCFL backlit 19" LCDs (I use LG L1942T + L1919S), mostly reading/writing in Linux console or just browsing the Internet.

As there is no DVI available, I used another HDMI and connected my notebook. The result was better, but still visibly worse than the old LG L1919S (TN panel) which has other flaws.

Anti-glare coating is definitely not semi-glossy on the 24" model. It's probably the same thing as with flicker-free 24" and 27" VA Samsung panels, where 27" is semi-glossy whereas 24" is more grainy.

Now, I'm no display expert, but I spend at least 10 hours a day staring at text and I have a hard time finding any good monitor that would suit office/text usage. I had similar issues with CRT monitors, where my 10 year old Peacock CRT would be way easier on eyes than brand new IIyama trinitron (which I've returned after a few days).

I forgot to add. It seems that for people that spend lots of time on text, high contrast doesn't seem such a great option. It doesn't feel so great when you read super white text from really dark background. Somehow, it feels easier on eyes if you read from TN panel with black background being dark-grey :)

I'm coming from a TN panel Samsung 17" 712n and I was hoping for a fairly sharp looking monitor and the EW2440L was on my short list with it's mostly flicker free design.

Any chance this one was a bad apple? I know VA panels have some drawbacks, but your experience seem particularly bad for a panel that seems to be reasonably well liked so far. Did you try anything to troubleshoot the issue further or did you simply return this monitor? What if anything have you replaced this monitor with?

Are you sure your video card and/or drivers/settings were correct?

When can I buy this monitor? EW2740L is already for sale, but not this 24-version. I can't find any info.

benq page EW2440L : http://www.benq.com/product/monitor/ew2440l/

Have you had a chance to have a look at this monitor in action? I am trying to see if I can find this monitor on display somewhere.

I am not sure if this particular one I've got was a bad apple or they are all the same. If you ever had an old CRT monitor where things started to get blurry over the time - especially when red color was slightly off causing things a bit fuzzy. This one had colors all in place of course, but somehow text didn't look sharp. I tried adjusting ClearType fonts on Windows 7, hoping that's the issue - no improvement. Decided to use that monitor with Linux instead and with Ubuntu fonts in the console things looked better. I've even taken an extra step and fetched Apple OS X fonts, which as slightly wider and more easier to read. This improved the situation a bit but I never managed to get it to a state where I would enjoy working with text on EW2440L.

I have mixed feelings now as I started to think it's maybe due to the pixel pitch size. Opinions vary and some people say that larger pixel pitch makes text easier to read as it appears bigger on your screen. Then others contradict it saying that the smaller the pixel pitch the more clear the text is (albeit smaller). I decided to check that on my own and went to the store to look at Apple Retina. It was a 13" display in a MacBook with 2560x1600 resolution. That gives us 0.1119mm dot pitch size. Nearly 3x smaller than the 24" Benq in native resolution of 1920x1080. Things looked really clear to read but I'm pretty sure this was thanks to OS X font rendering and Safari web browser helping with fonts as well. Then I checked the other Apple display, a regular non-Retina one, with 1280 by 800 pixels on 13.3" display. Things looked slightly bigger hence easier to read but I didn't notice any huge difference in the text sharpness. Both were easy on eyes when reading text so I don't think the pixel size is a problem here.

I think I would focus more on the anti-glare coating used. It seems to me it's easier to read from the glossy display rather than those with AG coating. But then on the other hand, my old LG L1942T and LG L1919S are both matte displays and I can stare at them for hours every day without eyestrain, while it took me 2 days to recover from the 1 day experience with Benq EW2440L.

In summary - it's either TN panel that is easier on eyes when you work with text, or AG coating, or both. I may just check if there is any glossy or semi-glossy TN panel with no PWM dimming.

And my list of monitors consisted of:
Dell p2414h
BenQ EW2440L
Iiyama X2483HSU
Samsung S24C750P

It seems Dell, Benq and Samsung are all matte displays. 27" Samsung is semi-glossy. Not sure about Iiyama.
 
Was thinking about using these side-by-side for thin-bezel, but
lack of VESA mount holes complicates things, not to mention
the cable mount sticking out directly from the middle of the backside,
I generally don't see that cable style except for really cheap monitors...

Was this over VGA out or HDMI or both? I was disappointed this monitor had no DVI-D :( I think it's a let-down of a display but I want to fiddle with one to make sure.

Before my 17" Samsung 712n lcd monitor I had a 10" (18" viewable) Samsung 900 IFT and THAT was a razor sharp monitor for a CRT. 0.20 dot pitch. Of course, the CRT technology is totally different. Either way, that monitor was perfectly sharp the whole time I owned it. I only sold it and got the 17" lcd because the 900 IFT was too big, bulky and power hungry for me.

The last display I had trouble with was just recently on an Asus N56JR laptop. It was 15.6" with 1920 x 1080 resolution. The text was small. I made the text larger but it still bothered me. I suspect the display bothered me because of the pwm which is would led me to return the laptop and I bought an Asus PC box and continued to research monitors and I found the Benq EW2440L. There are some Eizo monitors that look nice and have anit-flicker tech but they're a bit pricey. The Asus laptop screen looked so smooth and detailed I found it surprising that it bothered me, but I suspect it was pwm.

There is some difference between resolution, pixel pitch and dpi of text. Just because a monitor is high resolution does not mean that the text has to be tiny, but, it definitely seems that as you go from low resolution to high, the text really gets smaller. That is also an issue for me at my age (43-44).

I will try and have a look at the EW2440L in person. I also don't like the rear facing cable attachments and I don't like the lack of vesa mounting holes and the lack of dvi isn't great. Can't you just use a DVI to hdmi adapter and make sure the video output is configured ok?

It would be good if you could try another EW2440L.

Was thinking of the BenQ BL2411PT instead. The 1200 res is nicer than 1080 for non movie stuff. BLB isn't too bad, nor is bright corners, but...it's still an issue. I'd love to see these two monitors together to compare. They both have speakers, but the BL2411PT has the vertical portrait option and vesa mounting which is nice.
 
@Bluesun311: I did try it over HDMI. Initially I thought it may be something with the first HDMI port so tried with the second one - no difference.

@morkys: Let me know your thoughts if you manage to test EW2440L yourself. Not sure I want to go through the hassle of returning another one with the same problem. I'd rather try something semi-glossy this time or TN panel, as they seem to have less agressive anti glare coating for some reason.
 
@deviant: Well, I am guessing you are on the other side of the world to me. I am in the Toronto, Canada area, otherwise, I'd check out your monitor.

Another concern of mine now is the off angle gamma shift. How do you find that with this monitor?

The alternative to this monitor that I am looking at is the Benq BL2411PT. It's an IPS 16:10 monitor. So it's between the possible sharpness issue, and gamma shift of the VA panel vs the off angle low light glow and possible black light bleed of the IPS panel. The BL2411PT is 16:10, has DVI, display port and dsub and no HDMI and it also has vertical positioning.
 
Gamma shift was visible, viewing angles are definitely not as good as on IPS panel and you see black turn slightly into gray, it's already visible if you sit close to it and look left/right but it didn't bother me much. It's not as bad as on TN panel.

Back light bleed - it was pretty low according to my perception of course. Way better than IPS panels.

I wouldn't use it for gaming as it was clearly worse than TN or IPS but my main goal was text work. Black was black (except for gamma shift). I actually wonder now, if it had nice deep black because of the anti glare coating. Because things looked more sharp when looked at from 45 degrees angle and at the same time, it was turning more into glossy/semi-glossy (you could see objects in the monitor's reflection when desktop background was set to black).

I was thinking of BL2411PT as well but I may try something from other manufacturers instead. And I may just go for a semi-glossy, flicker-free TN panel (if I find any!) :)
 
Crap. I *just* ordered this monitor.

Any other opinions or info on it? Did OP have a bad apple?
 
Just ordered one myself after testing out the Asus VG248QE over the weekend, nice and fast, but the blacks on that one were killing me, gonna just have to deal with some lag and blur to get the blacks back. Coming from a 1920x1440 CRT...

This monitor big brother got a pretty good review, was hoping this one is similar enough. http://pcmonitors.info/benq/benq-ew2440l-and-ew2740l

Cool. I had the same problem. I was VERY close to ordering the VG248QE, but was afraid the blacks would drive me nuts.

My EW2440L arrives today and I will let you know what I think.

Please share your thoughts when you get yours as well, because I am curious what you think, since you have used other modern screens lately and I am sort of in the stone age right now.
 
Mine arrived today. I absolutely love the image quality. I have never seen such good blacks nor lack of black light bleed. Impressive.

However, I am having a problem with text. The text is NOT being properly mapped pixel to pixel. On this forum, with the grey background, I can actually see blue/teal pixels around some of the letters.

Please tell me there is a way to solve this so I don't have to return this beautiful display.

EDIT: OMG. I am an idiot. I just discovered it was being caused by the Windows 7 feature, "Smooth edges on screen fonts."

Apparently my old monitor did it as well, but this new one is so clear that it stood out a lot more.

Wow.

Excellent. That's what I wanted to hear. What are you using it for? Done much gaming on it yet?

I bought it primarily for gaming. I was a little nervous, because there aren't many reviews, and most of them say it is good for office work and "even a bit of gaming," or whatever. However, I picked this because I wanted good colors, good blacks, low back light bleed, etc.

So far I have really only played some Elder Scrolls Online with it, but it looks gorgeous. It isn't a super qiuck/responsive panel, but it gets the job done. I also turned off all the lights and loaded up Amnesia to see how it handles the darks. It was like playing a totally different game compared to my old monitor.

I haven't played any shooters or fast paced games on it yet, but will try some more stuff tonight.

So far it is great. I guess my only complaint so far is that I'm not used to a semi-glossy panel. I can see the reflections of lights in the house, and even myself in it at times. I actually had to turn off the TV that is in the same room, as it was producing a fuzzy rectangular glow on my screen.
 
@ Cronuss, good to hear so far! I'm being hopeful this will be the one. You get a good deal on it? I bought it from NCIXUS.com for $199 +$6 insurance, ordered on Monday, still hasn't shipped, grrr!

Was hoping to test it out this weekend. Have 30 days to return the Asus VG248QE to Microcenter, so lots of time left for comparison - I'm sure its going back though, dark scenes just look like shit compared to the CRT I had been using for years. Shame LCD/Flat Panel tech is moving so damn slow, I really hate the things (back lit displays) as they are now. Come on OLED already!
 
I'd be curious to see what other owners have found to be good calibration settings.

Whatever they did is quite likely completely irrelevant for you. Using ICC profiles and settings others made is rarely ever useful to your unit in particular.
 
Hi,
I'm interested in this new BenQ as well!

  • How is the brightness uniformity on the sides / edges?
  • How does it look when you lower brightness to 10%?
  • Do you see any coating grain on this display?
  • How is the stand? is looks like a fixed stand? how high does your lower bezel come from your desk?

I've personally tried the Iiyama X2483HSU and Samsung S24C750P
I returned both, but if I find a S24C750P which doesn't have bad (sub)pixels or other anomalies I might keep that one.
I really like the coating of that Samsung, it's really neutral semi-glossy. Not grainy and not too much reflective.

Thanks!
