vegetalebA bit OT but how do you search the forum? I tried LS24F350 on top right but it didn’t find any result
PCM2The only search facility you will see whilst on the forum is on the website footer, is it not? Where you sign in. 🙂
Also, the preferred model designation is S24F350(FH). Samsung adds all sorts of annoying prefixes (L) and suffixes (various regional designations) and it causes no end of issues with users trying to find information.
vegetalebSo I finally got an Lg 24mp59g ips. It has 2 Reader modes, I think one has pinkier whites and the other less contrast, unfortunately beside brightness we can’t modify these modes, I would love to crank up or down the contrast or blue levels.
Also something annoying is the ips glow or bleed, strangly enough it doesn’t appear that much on pure black backgrounds, but much more with blue ones. An obvious example is the win 10 “shutting down” blue page where it looks like I have large darker areas on the upper and lower parts of the screen.
I took an ips screen to avoid the VA color shifts but when I see these “clouds” I wonder if I didn’t do the bad choice.
In photo editing though I don’t notice this problem unless there is a pure blue sky or/and snow taking more than half the screen.
And yes I just tested it in daylight and with Photo mode too so it’s not Reader modes relatedPCM2You could create your own LBL setting by adjusting contrast and colour to your taste. But I suppose that would overwrite your main settings and you wish to activate and deactivate the LBL setting, so that wouldn’t be practical. What you observe with the solid backgrounds is not specific to IPS, they’re uniformity issues which I’m afraid can affect any unit of any particular model. Unless they have a guaranteed uniformity spec. and uniformity compensation setting, which only expensive models have and which come with their own issues. As you describe it sounds quite extreme, though, which is unfortunate.
vegetalebMy old benq tft screen E2400hd was better in that matter.
Ok first shot at 70% brightness and the second at 10%
https://preview.ibb.co/dfSuL9/IMAG0146.jpgPCM2Yes, that’s a rather sever uniformity issue. Not typical for IPS, perhaps not even typical for all 24MP59Gs. Although with some of these almost unusually cheap models (LG have many) the manufacturer does sometimes use its lower-grade panels rejected for use in somewhat more expensive models. So perhaps that’s quite average for the model, I’m not sure as I have no experience or user experience to share.
vegetalebDo you think I should ask for another unit under warranty?
The problem here in Lebanon is that they don’t have an echange period like in the US on new items, the only solution is to ask for the warranty to work and even for these cases I don’t know if they will accept or say it’s normal for “cheap” lcds.
On a positive note I didn’t find a single dead pixelPCM2I think it is worth asking for a replacement under warranty. I’d be surprised if all of the units of this model were like that, so it’s worth asking and seeing what happens.
vegetalebI talked to the shop, they don’t accept a swap to a more expensive model even if the nylon is still all over the screen and I pay a difference. They will take it under warranty if LG terms and conditions are compatible, I checked them online and couldn’t find a mention of uniformity, so I guess I will have to call them Monday.
I am starting to regret the BenQ EW2775ZH , they have a better quality control and more options for LBLvegetalebHello
I am finally selling the lg and most probably getting the benq.
Do you know if it’s matt and anti reflective enough?
Lbl and flicker free it’s a solid choice, I just have to see if it also check this eyes protection feature too 🙂PCM2BenQ models are pretty much all matte anti-glare, like the vast majority of monitors. Light matte anti-glare in the case of the EW2775ZH (and all current 27″ BenQ VA models).
vegetalebThank you fir the fast answer as usual
vegetalebFinally received the benq ew2775zh.
What a superb screen! I loved the matt plastic it makes it much classy than the lg I had.
I tried the lbl+ modes and the stronger one is “dark room”, though the blue(s) are still blue, no pink or orange hue like on windows 10 night option or Reader mode of the LG. I wonder if benq is using a hardware filter while other are using pure software, or their lbl is less agressive?
I compared it to other modes like cinema and its definitely less blue and less bright, but no warm whites.
Is it normal for an lbl?PCM2All ‘Low Blue Light’ settings on monitors are hardware filter based. They essentially work by shutting out light from the blue subpixel (blue channel). The LBL modes on the EW2775ZH do shift the colour temperature somewhat, but they aren’t quite as aggressive in that respect. That’s partly because BenQ uses a gentler shift of colour temperature combined with a backlight that has a shifted blue peak (this shifted peak occurs regardless of ‘LBL’ being active or not). So they don’t rely solely on reducing the blue colour channel. It’s explained in our news article on the monitor.
Considering BenQ’s LBL settings more broadly, they don’t just whack down the blue colour channel like some models do – they also reduce the green colour channel and slightly reduce the red colour channel. By doing this there is an effective reduction in blue light output, but the image remains more balanced with a less obvious perceived shift in colour temperature or tone. Your eyes can certainly adapt to that more readily than the more extreme shifts caused by using ‘Night Mode’ in Windows 10 or LG’s ‘Reader’ setting on your previous monitor.
And I’m glad you’re liking the monitor, I hoped this would be the case. 🙂
vegetalebThanks
Yes near my sony tv x900e it looks like its little brother, the brushed black design of the leg and back are superb for a monitor that price. The only negative is the pixel density if too close(30-40cm), but at 60cm it’s already pretty good I don’t see the pixels and the screen is big enough anyway to keep a distance.
So for lbl its all but good news then, I will use lbl multimedia in daylight for my photography editing as the wb won’t be bad.
I also liked the fact we have more settings to play with than with Lg’s Reader even if lbl is On.vegetalebI have read your article about my monitor, it says the short wave blue light is taken out by the lbl+ but not the long wave that could harm the eyes, but then in this article it says that some more agressive lbl modes are there like dark room, but is the dark room mode free of all bad blue light or the long blue wave will still be there?
PCM2Firstly, I’d like to say that harming the eyes isn’t really something I would worry about with any LCD monitor.
The blue channel is still reduced significantly, which means that all wavelengths of blue light are cut. The shifting of the wavelength means that the most energetic wavelengths are eliminated entirely. So yes, the strongest setting is effective in cutting out all blue light (and eliminating the most energetic wavelengths completely). I’ve also modified the news piece slightly to make it clearer how the ‘Low Blue Light Plus’ features fit in. And to reinforce the fact the wavelength change is a feature of the backlight that is always present, regardless of setting.
TVGGreetings! I have long noticed that this site pays especial attention to the Low Blue Light subject, so it may be the best place to post my query. I have just purchased the new Apple Mac Mini as the basis for my workstation because I believe it provides more flexibility than the iMac. In particular, I would like to take extra care of my eye health as I spend a lot of time in front of the computer monitor.
I assume that Low Blue Light technology really makes sense, and with a smart and complex approach can be effective even without significant degradation of image quality. But thanks to advertisers (these guys will definitely bury our civilization), I totally can’t figure out where LBL is implemented properly (better than others), and where it is just a trivial lowering of color temperature and yellow screen sorta f.lux “build-in”. That’s why I’d like to find out, which manufacturers are really work hard in this direction, and which are just lazy cheaters.
It’s also worth mentioning that I’m looking for some semi-professional IPS solution as sometimes I would like to have access to accurate color reproduction when need it, and besides, don’t want to lose much compared to iMac. For now my options are BenQ PD2720U / PD3220U, ASUS ProArt PA24AC / PA27AC and Viewsonic VP2768-4K (other options such as NEC, Philips, Dell etc. are also possible), but if it turns out that they can do nothing more to protect my eyes than I can do myself with a couple of clicks even on my living room TV, then maybe I should just buy LG UltraFine 5K and forget about all of this. Please help me figure this out.
(Sorry for my bad English.)
PCM2Hi TVG and welcome,
LBL settings on monitors are simply colour filters. So they are indeed just an alternative way of achieving what can be achieved on the GPU level, using F.lux for example. Or by manually adjusting colour channels. They are sometimes more useful than GPU-level of software adjustments in the sense that they can be calibrated more carefully to avoid impacting contrast or colour range as much. But ultimately they have the same effect on blue light reduction.
TVGYou say it can be calibrated more carefully, so maybe there are some manufacturers who provide LBL mode with a better balance between picture quality and efficiency than other brands do? For example, I know some monitors which have LBL function that makes them completely unsuitable for everyday use when it activated (color distortion is too high). It can be assumed that there are opposite ones, right?
