p.1 #1 · p.1 #1 · LG 24MD4KL for photo editing? Any challenge with lack of calibration & D65-only?


Hey all,

Is anyone here using the LG 24MD4KL for photo editting? Any issues, especially if you take the images to get printed? As-in, issues with mismatch in prints, color being off, brightness being off, etc?

I'm asking because I know on this particular monitor, the white-point is fixed at D65 and the ONLY "adjustment" that's user accessible is brightness. I even tried with low-level DDC operations but LG has locked everything except brighness adjustment out. I did buy these monitors once before and returned them* so I know my understanding of the limitations is true.

More boring stuff below if you care to read.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------
*I originally bought a pair these to use for my day to day engineering work and I found the monitor suffers from a LOT of mermism, the colors shift noticably off axis. If you're working with a "light" color scheme and are looking at lines of code or a web browser, the background shimmers as you move your head and is very disturbing. For photo editing, or video editing, with a "dark" color scheme, I suspect this is far less of an issue and is probably what the monitor is optimized for.

Why am I considering this monitor given the stupid lack of controls/adjustment?

I really like the combo of 24" and 4K pixels, the monitor size is big enough to be clear, small enough that with two monitors side by side my head isn't pivoting back and forth and the 4K "retina" (1920x1080 effective resolution with 2x number of pixels) sharpness is much much nicer to look at. macOS handles a pixel-doubled resolution really well and surprisingly so does Linux.

I'm using refurb Dell P2415Q's (sadly no longer available new) for my engineering workstations and really love the 24"/4K but in the monitors I bought, getting them to match even with a ColorMunki has proved to be a challenge so I don't want to go down a refurb route again.

I also bought and returned LG 24UD58-B which is a 24"/4K monitor ; I thought some of the negative reviews were mistaken but really the monitor just looked about 5x more "dull" than any LCD I've used recently (even with brightness cranked to 100%) and both monitors had really poor brightness uniformity. It was just terrible to look at.

So for 24"/4K this leaves just the 24MD4KL...

you know - typically when you print, you calibrate your monitor to your print viewing station or to how your prints will be illuminated ... are they going to be illuminated anywhere close to D65 light where they will be hanging / viewed ?!

This comment makes a lot of sense. Due to work I've been nomadic and don't yet have the pleasure of doing "real prints" of my own photos.

What is the process you follow? Do you use a colorimeter or something like that to profile the light in the environment where you put up a print? For example, if you're putting a print up in your home, do you carefully adjust the white-point of the monitor to match?

Similarly, if it's going in a gallery or something, do you profile the lights use to light up the photo and adjust the monitor to suit?

Basically I'm willing to bail on buying these monitors if it won't suit the task of monitors for image post-processing with a ultimate goal of making prints (mostly personal, perhaps some for sale).

I should have opened my post by saying I would like a good match between display and print but I have ancient knowledge of printing (dates back to using Kodak dye-sub printers) and I'm looking for feedback, even if it seems like something should be obvious here.

I was under the impression people use "soft-proofing" to help visualize the difference between a print / display, assuming that there is a profile for the display and the printer (actual paper being used, the actual ink/pigment) so I wasn't sure if the fixed D65 on those LGs is a real issue or not.

IPS screens go a long way to providing consistent colours and contrast when viewed off-axis, within reasonable limits - certainly within ergonomically sensible viewing situations.
IPS = In-Plane Switching and is a form of liquid crystal display. Absolutely worth the extra cost for photography work (IMO). The best screens such as from Eizo use IPS.

The shimmering is likely due to a crappy screen coating or just crappy screen glass.

The best screens do not have these problems. There is no doubt that Eizo monitors are expensive in absolute terms, but they last for years (even have a 5 year warranty), they have a very effective anti-reflective screen, excellent screen uniformity, excellent colour accuracy, and so on. They are a joy to use. Some are better than others in various ways but you'd be hard pressed to be disappointed with any Eizo CS or CG screen. I use a 27" 4k CS2740.

New Eizo screens are coming with greater dynamic range but that is irrelevant for printing because prints cannot reproduce high DR.

With appropriate monitor colour profiles in conjunction with the Eizo Color Navigator software, you will be able to preview what the prints will look like with reduced brightness and contrast and gamut and white point. For editing, you can view pretty much the entire AdobeRGB 1998 gamut and sRGB, etc. You either get an Eizo with a built-in calibrator or else buy something like an i1Display Pro Plus and use it with Color Navigator to calibrate your monitor. On my system, a calibration takes about one minute, but I repeat it several times to refine accuracy. Repeated calibrations effectively increase the cumulative measurement time to improve accuracy of the calibration.

What all this will not do is make unprofiled photos look "right", but if the photo has the right color profile information then it will look as accurate as it possibly can so long as you use color-managed software such as LrC, Ps, DxO, etc. Then your editing will be more appropriate and your prints are far more likely to look as you want them to - the first time you print them. This potentially saves money with minimal print wastage. However, you'll need to get your printer profiled too for best results, with a separate one-off profile for each paper/ink/printer combination.

See if you can find a place that sells Eizo and sit down in front of one for a while. You already know what you don't like, so try to see what you will like Even a quick glance will impress but give it time to sink in so you'll be confident about the merit of paying the higher price. Observe the shadow details and highlight details that most other monitors cannot distinguish. Note how consistent things look at any part of the screen. If nothing else you will become aware of what cheaper monitors are not showing.

High-end BenQ screens are nearly as good as Eizo screens. Certainly not as good but close enough that they both make most other monitors look like rubbish in comparison (for photo/printing work). They're cheaper too, but still not cheap. And they have shorter warranties.

When I think of all the money I've thrown at photographic and computer gear over the past 40+ years, Eizo (and other) high-end monitors have been a minor expense and have lasted the longest and been used the most. They have improved the on-screen appearance of every photo.

Alan321,

I was wondering if you were going to weigh in . I think you also had the P2415Qs at some point? That's what I'm using for my engineering machines and very happy with, all things considered.

The LG MDL24K monitor honestly looks and behaves to me like what I see with LG OLED TVs but I have no confirmation that the monitor is using OLED technology.

I have access to a larger CX-series LG OLED TV, to my eyes seems like it has the same type of mermism if you display a white screen (i.e. hook a computer to the TV) and look off axis -- a clear color shift. For video (the primary use of a TV) the brain adapts very quickly, it's a non-issue and didn't bother me at all. Maybe it would if I was the guy who did color grading on said production! Also, looking at the LG CX OLED TV "off-angle" when it's turned off, one sees a certain type of surface and reflected color and 24MDL had the same type of surface look.

So if LG adapted their TV technology for a monitor, perhaps with some of the internal polarizers and final "glossy" surface screen, it might explain why this model monitor is paricularly vibrant on axis but the trade-off is color consistence and accuracy off-angle.

I think Eizo is probably the way to go (no more NEC, sadly) while I think companies like BenQ are trying, makes more sense to go with a company who has been an industry leader in this arena for decades.
