Difference between LG 27" displays

[Goi]

Hi,

I'm trying to decide among the following. Prices are not in USD and are included for comparative purposes.
LG 27UD58-B ($400)
LG 27UK650-W ($450)
LG 27UD88-W ($500)
LG 27UD68-P($500)

They're all 4K 27" IPS displays, and are very similar. I'm wondering what are the major differences between them. AFAIK, the LG 27UK650-W is newer (2018) while the others are 2016 models, the LG 27UD58-B is dimmer (250nits vs 350 nits) and doesn't support height/swivel/pivot adjustments), and only the LG 27UD88-W has USB ports. Other than this, are there any big differences, especially in image quality, between them?

Thanks!

The 27UK650-W is the only one that supports HDR signals, however with it's specs of 350 Nits and 1000:1 contrast ratio, it can't actually display HDR in any particularly good fashion. But it still is the newest panel and the newest hardware from LG.

It also looks to be on sale at the moment, so it might be a good time to pick it up, it's normal price seems to be $550-500. Only in the last ~3-4 weeks has it seen it's price drop below $500.

Image quality-wise, they're all fairly similar, though the 27UD58-B appears to list NTSC color gamut support (72%), compared to all the others which list sRGB support (99%)

What's the difference between the 2 color gamut support?

No, no, and no. For tech work (looking at code, VMs, various tech tools, etc)

Basically just depends which color space you're working with more frequently.

If you're not going to be doing color accurate work, then it's not a big deal.

Honestly if this is the case, I don't particularly see a reason for you to get 4k at all at that screen size.
27" 4k ends up being GUI scaled to 150% in order to retain text legibility at normal viewing distances. In order to use 4k without GUI scaling at a normal desktop viewing distance requires a 38-46" 4k panel.

For reference, most people at a standard desktop viewing distance like a pixel density of around 100 pixels per inch (PPI)
22" 1080p = 100 PPI
24" 1080p = 92 PPI
27" 1440p = 109 PPI
43" 2160p = 103 PPI

27" 2160p = 163 PPI
At such a high pixel density, you simply can't read text at native scale, it's too small. Which is why you have to GUI scale to 150% on these panels. Making the 4k resolution a bit worthless(for your described use-case, higher pixel density has benefits in video and photo editing work, and gaming), since you're only able to effectively use 1440p equivalent.

My 40" 4K UHD TV that I use as a monitor, is at the edge of readability for me, at 4K native res for text while web browsing.

Totally agree. However, the 27" 1440p monitors where I am are actually more expensive than the 27" 4K LG ones I've listed above.

Weird, in the US anyway I can get cheap 27" 1440p monitors for ~$240-300. Whereas the cheapest 27" 4k (that isn't chinese/korean no name) is ~$340-400, and the newer models are generally all $450+.

But hey, if your market place is messed up, go for whatever makes economic sense. Just recognize you wont be able to take full advantage of the 4k resolution for your use-cases.

I highly recommend IPS over VA and TN LCD Display Monitors and TV's for Desk Top PC's.

In my experience with LG AH-IPS MONITOR Displays is that are great for watching Videos and doing Photo Editing but terribly Slow for Gaming. The AOU AH/VA IPS panel is much faster and descent for photo editing. LG IPS displays are great for large relatively cheap TV's.

I've no need for either a 4K or 8K Quantum Dot Panels that are still in development. A 27" 2k 144Hz 2560x1440p AOU AH/VA IPS Gaming panel does it it all for me at present.

Check out these 27" Korean and Japanese FAST 2K IPS LCD Displays at a descent price - I suggest you buy one now before they dry out; both these displays will play 4 and 8K video with perfect scaling and so will the old Samsung PLS-IPS QNIX 2510 display - How well depends on your video card: I can do it with an i7 2700K 3000 IGP, Normally I use X-Fire XSPC RAZOR 290X's under Win7 SP1 Ultimate.

If you want the most Video outta your DeskTop PC take notice - In my opinion all North American Display Mfgr's over price their products compared to Asian Mfgr's whom have the BEST Technology in their products for almost 1/2 the price. Insure your mouse is clean or have a FAST mouse with the MBest:
