Rated 5 out of 5 by from Nice size clear color! I have had this monitor for a few months the only issue I have is every once in awhile it will blink in and out for a second

Rated 2 out of 5 by from Adapter fail. I purchased this monitor with my new intel i7 NUC, which only features a DisplayPort in. As this monitor only has HDMI out, I had to buy an adapter however due to this, I can only reach a 1980x1080 resolution. The native resolution of 2580x1080 will only work in safe mode. There are multiple forums where people refer to this issue.

Are there any drivers for an iMac (21.5-inch, Mid 2011) The best picture I can get is 1080i

Asked by: Wayne0U812
The ENERGY STAR® Qualified LG 25” Class 21:9 UltraWide® IPS Monitor (25.0" Diagonal), Model # 25UM65-P is a Plug-and-Play monitor, meaning drivers are not required. Plug-and-Play is a standard that has been set for communication between devices. Modern operating systems (Windows, Mac OS, etc.), are able to recognize these devices, and use "generic" drivers to control them. These generic drivers provide full functionality to the devices they serve...^IFV

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

Is static a problem with the speakers on this monitor?

I have an LG25UM65P monitor and all of a sudden am having problems with static. Yesterday it sounded fine but today after i did my windows updates it sounds pretty bad.
Asked by: Nickle
We regret the inconvenience you have experienced with this monitor and its features. There have been no known problems with the speakers of this model. If the change occurred with the installation of an Operating System Update, it would be suggested to check with the Operating System to see if there were any changes made that would cause improper operations.

Is the display supposed to go all the way to the edge of the glass?

I purchased the 25UM65-P monitor and the screen does not go all the way to the edge of the glass. There is a 3/8" black strip on all sides. Maybe on the bottom right above the plastic area, it is only 1/4". When the monitor is off you also can see where the LCD area behind the glass ends which matches the dimensions above. If you measure the monitor diagonally, it is 25" viewing screen area with the black strips. So again, based on the pictures the screen should go all the way to the edges except from the bottom? Did I get a defective one or this is how they are designed and the marketing pictures are tweaked?
Asked by: sbk1
We appreciate your interest in this monitor. This display is designed with a 25” diagonal viewing area. The images listed on our website do show a dark area around the edges of the screen which appears to cover the space you have mentioned. It may be that, due to the size of the device in the pictures, the picture appears closer to the edge than it actually is.
