What People Are Saying

Rated 4 out of 5 by from Good monitor BUT NO 75HZ FOR NVIDIA (?!) The monitor is good for its price. I love ultrawide and I'll probably never go back to 16:9. It gives you so much more room to work on and it is much more immersive when playing games. The colors are nice because it is an IPS screen. Now I have seen with my own eyes what the difference is between IPS and TN and I will never buy a TN screen anymore. The screen is sadly not borderless like advertised on most of the images. (This I knew before buying the monitor.) The monitor isn't very stable and easily wobbles but not much. !!WHAT I DIDN'T KNEW BEFORE BUYING THE MONITOR!!: The screen is advertised to have a refresh rate of 75Hz, but apparently this is only available when you use FreeSync. This is nowhere to be found on the product page. I was REALLY MAD because of this. I knew 75Hz was only available through a display cable, but not that you would need to use FreeSync. (I have a Nvidia GPU.) (Still don't know if it really is the case but I see no other options or reasons why it does not work for me. So if anyone can give some help or a comment...thx in advance.) Overall this is a good monitor but if you really want an ultrawide monitor from LG, than go for the 29UM69G-B.

Rated 3 out of 5 by from great for productivity, for gaming just OK Good work space for productivity, but for gaming is prefered a 16:9 ratio. 75 Hz is NOT working on Nvidea cards, even whith display port=framme skiping. A great value product.

Rated 5 out of 5 by from Great Monitor with reservations A fine monitor at the current pricing, had it been the old retail not so much. Interesting format and very useable. The only complaint, while I give the monitor a 9 the joystick interface was designed by a 3rd grader. This would be much more efficient with a simple remote. It forced me to wall mount this device at the lowest position on my wall just to be able to adjust or select options. Over all rating a 9 joystick is a joke

Rated 5 out of 5 by from FAB Ultra screen We bought 2 of these monitors. Didn't realize the amount of desk space it needs. My wife has the LG 27" HD and I was about to buy that one. Then we saw a sale on the 29" Ultra Wide at Fry's. A little research, online comparison, visit the store to check out the demo model and take 2 home. Setup on #1 was a breeze, didn't need the install disk, Windows had drivers. On screen setup was easy, mostly to reduce the brightness and setup sound to my liking. It's so big and wide, I'm still getting used to it and trying to figure out where I should place all the different apps as I use them. It's an embarrassment of available screen real estate. So far, not a lot of Ultra-wide videos available and I'm not a gamer. Speakers actually sound pretty good, considering the size and the single AUX cable. I'll stick to my normal speakers. Monitor overkill? Maybe. Setup on #2 was a bit more problematic. My son accidentally clicked on some windows setting and suddenly the monitor speakers would not work. He tried everything, reset his windows sound, monitor sound and could not get speakers to work again. I had suggested a system reboot including monitor and that fixed it, but not before some serious consternation in my son's part. It's been 2 weeks. Buyer's remorse? Not in the least. Just wish there were more regular video for these screens. Working with all this extra elbow room? Priceless....

Rated 4 out of 5 by from Great Graphic Design Monitor I've had this monitor now for most of 2017 and it's been a solid monitor. The only problem with this monitor is the software for it, screws up everytime you plug in the HDMI cable, or when you put your computer into sleep mode and open it up all the applications that are on default on a different screen end up all being moved over to this monitor. I don't have this monitor as default it is for design only. Great picture, sound isn't to bad either.

Rated 5 out of 5 by from Great view The monitor has a great view en colors. You're able to use two or three program screens, at he same time. A 4k monitor for your computer at home, is'nt necessary.

Rated 5 out of 5 by from Excellent value Purchased this over a month back, and waited to see if it still works as good as the day I bought it before posting a review. Happy to say I remain a very happy and satisfied customer, with no issues to report. Using this of a mixture of gaming (FPS/TPS and action-RPG) and movie watching, and it works beautifully and looks great.

Rated 5 out of 5 by from The perfect size I use mine for work. I ready Blueprints most of the time and the screen size of the 29-UM68p is perfect for displaying blueprint pages which are normally very large. I can work without constantly having to scroll around the page to find something. When not using for that I can easily open a PDF and a spreadsheet and work on both.

Hi, I'm not able to use the 75Hz, only 60Hz. I am using a display cable and I have an Nvidia GPU (GTX1080). Is the 75Hz only available when u use FreeSync? Because this statement is nowhere to be found on the product page.

I have the monitor connected to my xbox console, where can I adjust the volume to the monitor?

Asked by: Frankkie
The monitor doesn’t have built-in speakers. So if you want to adjust the volume, there should be an external speaker connected either on the monitor or on the Xbox. ^AC
