What People Are Saying

Rated 5 out of 5 by from Incredible This is the very first Ultra wide Monitor I have ever purchased and honestly I could not be happier. The 2560x1080 plus my EVGA Geforce GTX 1080 SC make everything from reading news article, watching videos and running design programs amazing, multitasking is made so easy with this thing going back to a 16:9 will never happen. If I ever need to upgrade or get a new monitor it will be from LG and a Ultra wide again. Truth be told it is amazing. Thing is huge for a 29in.

Rated 5 out of 5 by from The perfect entry-level Ultrawide Monitor Pros: - 75Hz refresh rate - FreeSync - Split screen feature - sRGB > 99% - Aesthetically pleasing - Easy navigation for monitor settings - Useful software (OnScreen Controls) - Balanced resolution and screen size - Affordable (I bought this for $290) - Decent speakers Cons: - Not height adjustable - It's glossy plastic - Dust catcher - Included HDMI cable is not the best (micro-stutters at 75Hz, stable at 70Hz)

Rated 3 out of 5 by from Broke! Will update When opened the screen was in perfect shape. Beautiful display and color, no dead pixels. Was great for gaming and multitasking. Haven't watched a movie on it but itd probably look great. The stand is alright. However after about 2 weeks it completely stopped working. The power supply still works but the monitor won't turn on. Going to send it in. Will update depending on how well it does once I get it back. I love this screen, but the fact that it just stopped working so abruptly makes it hard for me to recommend this product.

Rated 5 out of 5 by from Love IT Awesome Monitor. It handles all my productivity on one screen. I would purchase another one for double the productivity. But I will have to wait :(

Rated 5 out of 5 by from Great features I bought my monitor about a month ago and lovedit every day. I like all the features it has and the ease of using it and how easy it is to get help from the help desk.

Rated 5 out of 5 by from Best Developer Monitor I was often challenged with finding space for two monitors to support my developer work, but not anymore. The 29UM68-P not only has dual imports (2 computers for example), the split screen application is awesome. I usually put my coding application on the left, my real time review on the right, and documentation/search on the bottom panel in a three way split setup. Many options and the quality of the monitor is unsurpassed in my opinion.

Rated 1 out of 5 by from Average monitor with major selling point failure I bought this monitor because the specifications indicated it could to 75hz @ 2560x1080 on LGs product webpage. However, it can only do 60hz which makes it a major failure in my book. LG even confirmed this quality assurance/marketing failure after I spent over a month trouble shooting and them working with their overseas engineers who designed this junk. The image quality is OK, but many popular brands do as good or better for cheaper prices than what I paid while living up to their other major selling points.

I use it as a TV sometimes (streaming video mostly). Is there a remote I can use to adjust volume and change inputs?

Asked by: MartinL07
I apologize, but no; this monitor has not been designed with an IR Receiver to be able to take a signal from a remote control. No such controllers have been designed for this monitor.

Hello I bought two of the LG 29um68 - p. I love the monitors but when I put them side-by-side there don't line up evenly. Is there a height adjustment that I'm missing?

Asked by: Ghostrider772
We appreciate your interest in this monitor. According to our information, it appears that the monitor stand is not supposed to be adjustable for the 29” version. It is still possible to test the stand to see if it can adjust in the same manner has the 34” version. For additional questions please contact our Customer Interactive Center at 800-243-0000.

Hi. Our monitor came today but it did not include the 4 mounting screws to connect the stand to the monitor. We could take a trip to the hardware store but there are no specifications for the screws in the manual.

Asked by: PK Rivera
We appreciate your interest in this monitor. According to our information, it appears that this stand should connect using 4 screws, each measuring 4mm x 10mm.
