What people are saying

Rated 5 out of 5 by from full view This is the best monitor I have ever used. Everything fits on the screen making it very easy to read/view.

Rated 4 out of 5 by from Good but could be a bit better I've connected my Macbook and at times a cable box to my monitor. The display is high quality although the software doesn't allow changing the aspect ratio on the side where the cable comes in. Reading stock graphs and charts out of proportion takes a while to get used to. If the software could allow more adjustments when two sources aspect ratios it would be 5 stars across the board.

Cannot change video output to the monitor  Whenever I try to go through the menu and switch the outputs and I press "ok" it goes black then goes back to main menu, it even says it's connected and it does the same thing when it asks to connect

Adjust graphics display

Graphics are stretched out wider when displayed on this monitor in comparison to my macbook pro giving me a "fatter" presentation than the actual image. How do I resolve this?
Asked by: jenius1120

Is the refresh rate really 75Hz?

I was curious if the listing of 75Hz as the refresh rate is correct, on places like BestBuy.com. I just bought this monitor and upon setting it up today with a DisplayPort cable (not HDMI), both Windows and Nvidia Control Panel show the maximum refresh rate to be only 60Hz. Is this supposed to be the case? Thanks.
Asked by: VinceTheStampede
We appreciate your interest in this monitor. According to the information listed on page 46 of the owner’s manual, a 75Hz Refresh Rate is available at resolutions of 640x480, 800x600 and 1152x864. The maximum resolution of 2560x1080 is available only at 60Hz. The Refresh Rate is to be a setting of the video card of the computer.

What is needed get this to work with a computer, I have a standard VGA HD 15 output on the laptop, and a cable to go to HDMI

Asked by: Coachmec
We appreciate your interest in this monitor. If a conversion cable is already in place, between the 15-pin VGA port and the HDMI monitor port, then all that remains is a compatible video resolution. Such resolutions can be found on page 46 of your owner’s manual. These will need to be set on the computer/laptop itself, in order to display the picture properly on the screen.

How can I get max resolution on this monitor via DVI?

It appears that the max resolution on this monitor is not supported via the HDMI ports. How can I connect from a PC DVI out to this monitor to get full resolution?
Asked by: mgdavey
The maximum resolution of 2560 x 1080 @ 60 Hz is supported via the DVI-D, HDMI and the DisplayPort as shown in the chart on page 46 of your owner's manual for the LG 29" Class 21:9 UltraWide™ IPS LED Monitor (29" Diagonal), Model # 29UM55-P. If you're not getting the full resolution you may need to check your video card or your cables...^IFV
