Graphic designers will surely appreciate the many features of LG's Mac®-compatible UltraWide monitor. The 21:9 widescreen and 4-Screen Split will simplify working with multiple graphics windows. Disclaimer: Mac is a trademark of Apple Inc., registered in the U.S. and other countries.

sRGB 99%

sRGB is the standard color space of ideal color reproduction. So, with over 99% coverage of the sRGB spectrum, this LG monitor is a great solution for professional photographers, graphic designers or anyone looking for highly accurate color.

*Disclaimer: Color mode conversion between Adobe RGB and sRGB is available on the "Color Mode" menu.

4-Screen Split

4-Screen Split

Multitasking doesn't have to mean shuffling back and forth between windows. With a single click, the 4-Screen Split feature divides the screen into as many as four customizable segments, two-by-two. Now you can see four different windows at the same time.

Disclaimer: *Screen Split software runs on Windows Vista/7/8 and Mac OS.

Dual Linkup

What People Are Saying

Rated 3 out of 5 by 1 reviewer.
Rated 3 out of 5 by eye catching Purchased this because of the price and it was a good match for my LG 3d tv. It took two days to find an 3rd party plugin to connect it to my MacBook pro! Once it worked I was impressed with the extra screen resolution and it dissent use much power. Photoshop and sketch up are great with the extra width. June 25, 2014

Answer: 
They appear the same to me. Under compare, the "Energy star" does not show on one but they are both certified, in fact i can not find any differences in specs. The "Expert Staff" should know your are talking about the 25um64-S and the 25um65-P. Really cant find it without the 65 in there? The 65-P can be found: http://www.lg.com/us/monitors/lg-25UM65-P-ultrawide-monitor

I suspect they are the same but the 64-S may have been specially packaged for Costco (i saw it there today, which brought me here) and possibly other warehouse stores. Many companies take the same hardware and give it a unique number depending on where they sell it.

I loaded the drivers and Screen Split software on Win8.1. The software appears but all the options are grayed out. How can I get this to work so I can split the screen?

Where can I download drivers online?

I recently purchased the LG 25UM64-S monitor and cannot locate drivers or software for it that works with Windows 7 64 bit. When I use the included CD's to download the driver and software it says "Not a valid 32 bit program".

Thanks,
