What People Are Saying

Rated 4 out of 5 by from Almost excellent The monitor is excellent in all but two respects. 1. Usb 3 ports unpowered when monitor is in sleep mode. 2. Volume has to be controlled on monitor instead of through the laptop.

Rated 5 out of 5 by from Amazing Picture on Xbox 1 X I shopped around for a monitor for my X1X for quite some time. The jump from HD to 4KUHD has been amazing. PUBG, Battlefield 1, and Monster Hunter look amazing.

Rated 5 out of 5 by from Sleek and Awesome I just unboxed my new monitor and set it up. It is beautifully styled and crafted. Upon starting it up I was treated to an awesome 4K screen. The joystick control works well and the down loaded "on screen control" works well. It is recommeded that you down load or print off the complete manual. Also the adjustable stand works easily.

Rated 4 out of 5 by from Still setting this puppy up. Im currently setting up this brand new monitor, my two pc's in my house do not have cd-rom drives to install the system software. on hdmi1 i have my gaming desktop, on hdmi2 i have my xbox one x, and from what i can tell this resolution will be amazing and a upgrade from last gen 1080p hd monitor already impressed with very little use. so my only Con is the actually setting up going on two hours not even getting to really enjoy this puppy yet.

Can two of these monitors be linked (daisy chained) together to give me dual monitors, using a Mac Pro?

Asked by: wyocowboy
Hi wyocowboy. GPU's usually have an inherent limitation in how many simultaneous displays they can drive; some can drive up to three displays, while others can drive four oir even six. You will need to chck the specifications for your GPU to ensure that it is capable of driving multiple displays. Secondly, the monitor needs to have a DisplayPort Out. The LG 27" Class 4K UHD IPS LED Monitor with HDR 10 (27" Diagonal), Model # 27UK850 does not have a DisplayPort (1.2) Out. However, it does have a USB Type-C™ (ver 3.1 - Gen1) with DP Alternate Mode and 2 USB Downstream ports. Display output is accomplished via DisplayPort Alternate Mode through USB-C. Alternate Mode lets a USB-C connector carry native DisplayPort 1.2 signals across the cable. The monitor serves as a USB hub so when you connect your PC to it via USB Type-C™, your PC gains access to whatever peripherals are connected to the two USB downstream ports. The read and write speeds may be capped if your PC's connection uses all four lanes which willcause data to fall back to USB 2.0 speeds so you will need to check your PC's specifications on that...^IFV
