What People Are Saying

Rated 5 out of 5 by from Excellent monitor! I use this monitor with my Xbox One X and couldn’t be happier!
Date published: 2018-02-20
Rated 5 out of 5 by from Alas! HDR! Quick back story; I already own the LG 27UD68-W and it's great! I'm a tech guy and a huge gamer. I've always gamed on TV's. We own a bunch of 65" 4K OLED TV's and we have many displays but I finally converted to gaming on a monitor and I haven't looked back since! I did research for about 5-6 months prior to purchase. I'm a college student with a budget so I chose the the 4K 27UD68-W monitor. Not to mention.. it comes with AMD FreeSync. Like what a deal? So essentially to summarize it all. I followed CES 2018 and waited for LG's new releases. I bought the new 2018 27UK650-W from amazon for many reasons. 1) Design. Slick. Nice metallic finish. Slim Bezels. 2) AMD FreeSync. 3) 4K and finally HDR!) 4) Screen size 27" wouldn't go higher than that. 5) last but not least, price. I have an Xbox One X and this is the absolute package. HDR10, 4K 60FPS, and AMD FreeSync supported both by XBX and the monitor. No screen tearing!! You cannot go wrong! Other 4K HDR monitors at 60hz will cost you a lot more. And as of right now there are not too many available. I hope all of you enjoy as much as I have!

Is the HDMI cable a hdmi 2.0 cable?

Asked by: WayneOG14
Hi WayneOG14. Not to sound rude or condescending, but there is no such thing "4K" HDMI cables or "HDMI 2.0 cables". The version numbers for HDMI refer to the HDMI ports on devices. The LG 27" Class 4K UHD IPS LED Monitor with HDR 10 (27" Diagonal), Model # 27UK650-W has 2 x ver. 2.0 HDMI ports that are HDCP 2.2 compliant...^IFV

What is the Freesync range of this monitor. The specs, price, and release date are all out but this piece of information is missing

Asked by: ryan b b
Like I said the price and release date HAVE been announced. The price is on this page and the release date is listed on the retailers you link to. Seems ridiculous to be doing preorders when you can't be bothered to release the full specs.

Does it support 4k 60hz via DP port, and two HDMI ports? And I think only two HDMI ports support AMD Free-sync, if so, do they have the same frequency range of Free-sync?

Asked by: beichen
Hello, it only supports 4K at 60Hz on HDMI ports. For the Free-sync, it supports both DisplayPort and HDMI. ^AC
