What people are saying
Rated 5 out of 5 by from Best Monitor I Have Ever Owned I bought this after a lot of research to use with a new computer which I bought about a month ago. I could not be happier. I am using the Type C connection but also compared it by connecting to an older computer using an HDMI connection. This monitor came will all the cables a person could need. I did not need to purchase one thing extra.

Rated 5 out of 5 by from Great features! I bought this monitor recently and la la love it! The size is perfect, the speed is great and the density of the graphics is excellent. Oh and I love the aesthetic look with my gray space MacBook Pro.

Rated 3 out of 5 by from Loved it so much I bought another - but bad colors I got a new MacBook Pro with Touchbar in late 2016 and treated myself to this display to accompany it. I loved everything about it - bright, vivid colors, crisp details, one-cable charging/output, easy menus. I decided to buy a second identical one two years later. I would have given it five stars until the second one arrived. Unfortunately, the second one immediately had an issue with its coloring, with both displays set to factory default settings. I do not professionally edit photos or videos, but even simple tasks are distracting when the new display has an obvious yellow tint and the old one is a perfect white on web pages or documents. Making matters worse, my new one is still under warranty, and I have now returned it to LG twice for repair or replacement. Both times, after going through the effort of shipping my monitor, being without it for two weeks each time, and reconnecting it two two different computers (a Dell Latitude from work as well as my MacBook Pro), the same display flaw occurred. I am nearing the point of giving up. So I'd give the original display five stars, and give the newer display one star, averaging out to three stars. I have read horror stories about LG service, and I am basically living it. The second time I sent it in, the support rep said that they would probably just replace it - but they did not, they just replaced a different part than they replaced the first time. I don't see how such a visually obvious coloration flaw can pass their quality/calibration checks.

My LG 27UD88 will no longer connect to anything with USB-C - I tried different devices and different cables.  Is there any way that the USB-C port has become disabled? I've also tried the reset that is in the menu on the display.  HDMI works

I use this monitor with my 2017 MacBook Pro 15 inch. Every time I use it it causes the fan on my laptop to spin fast, even when there's nothing rendering in the background. I use final cut pro a lot.

Asked by: adamame
It's a known issue of Macbook Pro 15, only when using external monitors on HDMI/DisplayPort/other adapters. If you use it on Type-C it will not cause any heat.

Connecting the monitor to my MacBook Pro via HDMI, and there's no sound via the speakers.  I can get sound via the monitor's headphone jack, however.  I've maxed out the volume using the button on the monitor and the output is set to the monitor. Help! 

Asked by: IreneK
Hello and thank you so much for your inquiry. The 27UD88-W does not have built in speakers, however, it does have the 3.5mm jack for headphones or to connect external speakers for sound. ^AC

I'm interested in the 27UD88-W to connect to my 2017 MacBook Pro. From all indications, it should work just fine. Does in come in black though. I really don't care for the white on the back of the display.

Asked by: jmikeback
The "W" at the end of the model number for the LG 27" Class 4K UHD IPS LED Monitor (27" Diagonal), Model # 27UD88-W indicates the color. If a black version of this was available, it would have been indicated with a "B" at the end. Regrettably, there isn't a black version available...^IFV
