Rated 5 out of
Crisp and brilliant displayI bought this several weeks ago and have not been disappointed. The features that come with the monitor were a pleasant surprise and easy to use. I especially like the ease of changing the preset settings for what I happen to be doing whether I’m surfing the net or watching a video. The multi screen features are handy as well. I’m very happy with my purchase and the price.

My 34" monitor shows only at 640 x 480 resolution once my Macbook Pro wakes up instead of the correct resolution after I updated the OnScreen Control application. Is there anything that can be done to correct this problem?
Asked by: Gdavis
Hi Gdavis. The issue is what your graphics card is set to output and not with the LG 34" Class 21:9 UltraWide® Full HD IPS LED Monitor (34" Diagonal), Model # 34UM59-P. This monitor has a resolution of 2560 x 1080 and will always play content at that resolution. You need to choose Apple menu > System Preferences, click Displays, then click Display on your computer. You then need to press the Option key while you click Scaled to see additional resolutions for the second display. Then select a scaled resolution option for the second display...^IFV

The VESA mounting holes are not flush with the rest of the monitor. How can I use a normal 100mm VESA desk mount with this monitor? All mounts so far cannot fit inside the mounting area.
Asked by: Thomas66
The 34UM59-P is able to be mounted with mounts that use the VESA pattern 100 x 100. Information regarding installing the wall mount plate can be found on page 13 of the owner's manual which can be downloaded here: http://www.lg.com/us/support-product/lg-34UM59-P#manuals ^CP

My monitor no longer receives a signal from Mac OS 10.13.3. I've tried calling and they have been no help.
Anyone else have this issue?
Asked by: Kujo13
Hello, try first replacing or using another HDMI cable, then connecting it to the other HDMI port on the monitor and check the input. If that does not work, we will need more detailed information. ^AC

Does this monitor have speakers, or is the only audio output the headphone jack?

Hello! Which model would complement my LG 34UM59-P (placing next to mine)? I'm very particular when it comes to details, everything has to be the same (bezel width, size, style). Same design monitor, just 16:9. Stand not so important, will use dual stand.
