What People Are Saying

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.

Rated 5 out of 5 by from Great Wide Screen I purchased this for on-line gaming and am completely satisfied with the quality of this product.

Rated 5 out of 5 by from Amazing for some gaming and serious work I have primarily bought this work work. As a developer I need to fit to a screen a lot of things to speed up my work. Having a 34" monitor I cannot say how much easier my work become. At the same time I occasionally play some games like Dota2 and league of legends. I can say only positive words about this screen when it comes to basic gaming. I am sure this wouldn't be the greatest screen for highest level of gaming, but I can say for the price it is really a best buy in that category of 34" ultra wide screen market

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.
