What People Are Saying

Rated 1 out of 5 by from PROBLEME WITH MACBOOK PRO INCOMPATIBLE With MBP 2012 no resolution 2580x1080

Rated 5 out of 5 by from Great product When I saw this in the Best Buy showroom I was hesistant to get this product, thinking this can't be good. After some site surfing in the store, and a great deal, I bought it. The brilliance is consistent with all programs, sites, audio and visual. We use tablets and docking stations, and this solved our problem of two monitor hookups with a single output very nicely. Great deal, excellent product.

Rated 4 out of 5 by from Great for multitasking Great monitor for multitasking. I use it with the screen split in two connected to my MacBook Air. I have two browsers open at the same time side by side, for two different aspects of my two jobs.

Rated 5 out of 5 by from Right source for today's intellegent consumer Coming from a retired motion picture/television (analog) technology background - this 21:9 ultra wide format is a step forward in the right direction as an alternative if your creative purpose is graphic arts, photo editing or video streaming TV cable programs i.e. Net-Flix, Hulu Plus, Google View, etc (as a frugal economic prospective). However the 1080 X 2560 resolution could be better served at 1440 X 2560 to round this monitor out to near perfection, with it's inherent realistic color depiction, which it has right out of the box.

Rated 5 out of 5 by from Different and Great!! The overall quality of this monitor is great. It is different from what is out there in the market. The software that comes with the monitor is very easy to install on any PC or Mac. Once you install the software, you have many sizing options for your screen. I personally like the split screen. I can do work on one and see the news on the other. The image quality is crisp and detailed. I am thinking of upgrading to the next model up because of how great this one turned out to be. Thanks LG!

Rated 5 out of 5 by from Great monitor This monitor is awesome. Especially for the price I paid! Wasn't even looking to buy a monitor the day I got this, but I'm glad I saw this. It was on sale for 100 dollars off. Its picture is amazing. The sound is not bad for a monitor speaker. Plenty of features and love the look. My favorite feature is the split screen.

Is this monitor compatible with Windows 10?

Asked by: Walter153
LGJoel, I had heard that it will be Win10 compatible or that new drivers will be released by LG in October. I agree that it _should_ be class compliant, however my audio stopped working over MiniDisplayPort as soon as I upgraded to Windows 10. Can you tell us if there is anything new on LG's front to support audio over MiniDP with Windows 10, or what other configurations might be necessary? Thanks!

Hi I have a Mac book pro using a software switch ResX to get the resolution I need, but after el Capitan update I am no able to get the resolution so is there a way to get from you the timing parameters (or if you are able to tell me how to get this)

Asked by: Aargenis
The only information available with regards to HDMI Timing for video is tabulated on page 41 of the owner's manual for the ENERGY STAR® Qualified LG 25” Class 21:9 UltraWide™ IPS Monitor (25.0" Diagonal), Model # 25UM65-P. If you are unable to get the resolution you need, you may need to check the GPU in your Mac Book Pro and see if it has a scaling option or contact the GPU's manufacture for the timing parameters...^IFV

gaming details

what is the refresh rate on this monitor? i want to get around 120fps and i dont believe that is possible on a monitor with less than 120hz. also is it hard to set up multiples of these monitors?
Asked by: Garfunkle13
The LG 25” Class 21:9 UltraWide™ IPS Monitor (25.0" Diagonal), Model # 25UM65-P is 2560 x 1080 @ 60Hz. If by "multiples" you are inquiring about Screen Split, there is a Software CD that is packaged with the unit that allows you to install LG Software Monitor for the Screen Split program which automatically splits the program window as desired...^IFV

RE 34UM65-P, Can you split the screen(PBP) other than 50/50?

We are using the screen for a Oral surgery. We'd like to use the PBP to split the screen say 60/40 or 70/30 to show the xray on the left and the Vitals monitor on the right. Is this possible? We only seem to be able to get a 50/50 split. Thank you in advance for your assistance. Brian
Asked by: Bj440
We appreciate your interest in this 34” monitor and its capabilities. This unit is designed for operations with a 50/50 split screen. It does not have the capabilities for adjusting the pictures sizes further.
