What People Are Saying

Rated 5 out of 5 by from Great Monitor Very clear. No dead pixels. Use it professionally and personal use.

Rated 5 out of 5 by from Quick setup, excellent resolution I was looking for a monitor that could display the higher resolution of a new computer, but not excessively large for my home office. This LG monitor fit the bill exactly. The setup was simple, and the 3840 x 2160 resolution is excellent.

Rated 4 out of 5 by from Great picture and features! Does this computer have speakers? it seems like it does underneath and there are audio settings but i can't get the speakers to make any noise, I haven't found anything about if it even has speakers or not. The black color correctness is extremely useful, and the image is the most beautiful i have ever founed

Rated 5 out of 5 by from Awesome monitors My wife purchased one of these for me about a month ago as a gift to replace a dead 24inch and I was so happy with the quality, I immediately asked her to purchase a second exact model from Costco ASAP. If you decide to go with these you will not be disappointed. Only regrets, I wish I'd gotten them sooner and I wish they had a bit more adjustments(height) in the stands.

Rated 5 out of 5 by from Superb quality I wasn't sure if I wanted to go with two monitors this large, but I'm glad I made the choice. They fit well side-by-side on my desk, and it gives me the ability to take advantage of running apps full screen while still having a second source for reference (ie, looking up something online).

Rated 5 out of 5 by from Great 4K PC Monitor I bought this LG Ultra HD 4K monitor to take full advantage of the higher-end NVIDIA GTX 1070 graphics card in my new Dell XPS desktop computer which I use for photo and video editing and viewing. The GTX 1070 card DisplayPort outputs video at a resolution of 3840X2160 at 60Hz and that is the setting I use for all of my computer work with my LG Ultra-4K monitor. At that Ultra-4K resolution level the LG 27UD58-B has outstanding color, very quick screen performance, and has never shown the least indication of any negative viewing or performance issues with any large format photos or high-speed videos during my editing, rendering, or viewing. And all photos and videos -- no matter the source, including those streamed from the Internet -- are displayed in wonderful full Ultra-4K format on the LG monitor. Setup of the monitor with my PC was pure plug-and-play, as all I had to do for the initial install was connect the monitor DisplayPort cable (the monitor comes with both HDMI and DisplayPort connecting cables) to my NVIDIA GTX 1070 card and fire-up the PC. I use the NVIDIA card device drivers because they are frequently and automatically updated by NVIDIA, but the LG driver I initially used also worked well. I have found the monitor settings easy to modify and optimize via the included software which can be downloaded and accessed via the PC or accessed directly using the menu toggle button on the bottom front of the monitor. All in all, I believe this monitor is an excellent and reliable product that I can recommend without hesitation for use as a desktop PC Ultra-4K monitor.

Rated 5 out of 5 by from Outstanding clarity and resolution ! This is the best monitor I have purchased in this price area. It has 4K resolution at a price tag no one else can touch for its size. It's an excellent gaming monitor, demanding fast response time, for that much needed split second reaction. Gamers you WON'T go wrong with this beauty.

Rated 5 out of 5 by from Perfect price/quality I bought this three months ago and happy perfect experience vision. It's all about small things.

Hi Would this monitor work with a mac pro mid 2015 i5 8 gb ram iris card. On 4k 60hz ? And what should i use mini dp or hdmi port? Thanks

Asked by: Jaafar
Regrettably, we do not have any information for your mac pro mid-2015 i5 8 gb ram iris card to advise you if it will work with the LG 24" Class 4K UHD IPS LED Monitor (24" Diagonal), Model # 24UD58-B. This monitor has a maximum resolution of 3840 x 2160 @ 60 Hz and has 2 x HDMI Ports (version 2.0) that will support that resolution when HDMI Ultra HD Deep Color is set to on and a DisplayPort (version 1.2) that will also support that 4K resolution @ 60 Hz. We suggest you refer to your owner's manual for specifications for your Graphics Card's capabilities and check the specifications for its HDMI Video Output and DisplayPort or native Mini DisplayPort output to determine if it will work. It may only have Support for 1080p resolution at up to 60Hz, Support for 3840-by-2160 resolution at 30Hz and Support for 4096-by-2160 resolution at 24Hz...^IFV

Just bought this monitor.  Looks great.  It does have audio controls, but I don't know if there are speakers or is the headphone jack just a pass through for external speakers?  Thanks.

Asked by: Iloc
The monitor does have internal speakers for sound. It is suggested to ensure the volume is turned up on the monitor and that the audio output of the PC is set to the monitor. If this does not correct the problem, please contact us at 800-243-0000.
