What People Are Saying

Rated 5 out of 5 by from Great Monitor I don't know why other people are complaining. Me and a colleague both have this monitor and it works perfectly! I have tried 3 other 4k monitors (Samsung, HP, Acer) but this one is the best! It works right out of the box. The stand is great. A lot of the other stands on most 4k monitors are cheap or not sturdy. This monitor has the menu button on the bottom to switch inputs easily. I can switch between my MacPro connected with a DisplayPort cable, my 2016 MacBookPro 15" with touch bar using USB-C and a 2013 MacBookPro 15" with HDMI. No problems switching between them and all work great! I have no wake problems, no flickering problems. Another cool feature that I haven't seen on any other 4k/UHD monitors is the extra USB 3 inputs. One has quick charge so I can charge a speaker, my phone or iPad. The color is great!

Rated 1 out of 5 by from Junk, Won't Wake Up Bought this back in late December for my new Apple MBP w/ Touchbar. This monitor has been a nightmare: won't wake up from sleep, you can hear static discharge from the USB-C cable when you unplug it, flickering, turns off (or on) at strange times, self-adjusting brightness that always fails to please. Do yourself a favor and buy something else. All that said, great picture when it chooses to work! About 10% of the time!

Rated 2 out of 5 by from Bugidisplay with cheap design I got this monitor and I sold it away cause it did not work properly. I have new 13" MacBook Pro with USB-C and also 12" MacBook Pro and I used this display with both computer and they have serious problems. 1.) Original USB-C wire didn't work so I had to buy new and after this some problems was gone. 2.) I am using my computer clamshell mode and I use separate keyboard and mouse. When I tried to wake-up display from sleep the computer woke up but not LG display. So I have to connect and disconnect cable manytimes per day. 3.) when I took USB-C cable from my computer after this my computer crash time to time. 4.) With 12" MacBook display was flickering every 10seconds! So I couldn't use display with MacBook. 5.) Display got extremely bright white light down in display and it is flashing when it goes sleeping. So if this display is same place where you are sleeping or room which should be relaxing this LG is destroying that! You can't take that fiction away. I also contact LG support and it was Awful! I heard that it's not working at all and no I have my own experience from that. It is Horrible! I also google display and other user are experience similar problems whit this display. So I don't recommend this display even some reviews are saying that this display is good. NO IT'S NOT. DON'T Buy!

Rated 5 out of 5 by from 4K that works great out of the box I brought this monitor home expecting to have to do the usual configuration to get the resolution to 4k at 60Hz, but everything booted up at the proper resolution the first time. My monitor is connected to an HP Spectre x360 15.6".

Rated 5 out of 5 by from YES! I did charge I bought this to go along with my new late 2016 MBP with usb-c. It does charge after the 10.12.2 update. Albeit, very slow but I don't care. One cable life rocks! I do wish the USB was 3.1, but I can live with it 3.0 for what I needed. Sound works as well.

Rated 4 out of 5 by from OnScreen Control Hey, love the monitor overall - but the OnScreen control software is really slow when you need to bring out the menu to change screen splitting. The setting is reset every time I have removed my Macbook, so I need to do this quite often, and sometimes it takes a LOT of time to even get the menu to show. An update of this software would be very nice!

Does this monitor loop out through the HDMI ports? As in, can I connect it with USB-C or HDMI to a computer as an extended display and loop that extended display out of the monitor to replicate on a TV?

My laptop has a FHD display. Would I be able to view 4k on the monitor even though my laptop is not 4k? 

Asked by: Abarbosa15
The LG 27" Class 4K UHD IPS LED Monitor (27" Diagonal), Model # 27UD88-W will display images at a resolution of 3840 x 2160 if presented with content that is in that resolution. It is not a matter of what your laptop's display is, but of what your graphics card is capable of pushing out to the monitor. If your graphics card cannot push out a resolution of 3840 x 2160, you are not going to get a 4K signal on the monitor even though it is capable of supporting that resolution...^IFV
