Rated 5 out of 5 by from Huge! Bought this very affordable Ultra Wide monitor from Costco. I sit about 2 feet away from this screen. It feels like an IMAX screen : - ) Easy installation and drivers. I might just buy another one for my office!

Rated 5 out of 5 by from Better than Expected! Got this model (34UM61-P) after a lot of web searches and comparisons. I bought it from a "Scratch & Refurbished" source, but the unit was flawless! However, the PS (Power Supply) went out after the first day. It worked one more time, and blacked out. After connecting another PS, it has worked better than expected! I would recommend it to everyone. The 2560x1080 res is great for me (I'm not a gamer), but if you are not on Win 7 or higher, you can't get the full benefit of the 34" screen, as 1920x1080 with 72Hz might be the best you can get, but the screen is not full.

Rated 5 out of 5 by from Great Monitor I bought this monitor a few weeks ago. It is a beautiful display that is large enough to allow me work in multiple applications without needing a separate monitor. Installing the monitor was extremely easy and the view is fabulous. I have gotten rid of my second monitor creating extra space on my desk. I highly recommend this monitor!

Rated 4 out of 5 by from Great Monitor Great looking monitor. I had trouble finding the Mac drivers for split screen functions ( LG's omg screen control). I ended up downloading them for a different model and they worked.

I already have one of these monitors and I love it. I was considering purchasing another one, but is it possible (and how difficult) to connect a second widescreen and split the way I can on the first? I am running this off of my Lenovo laptop. Thanks!

My desktop only has DisplayPort.  Will this monitor work if I use a DisplayPort to HDMI cable?

Asked by: chris171
We are unable to confirm whether the cable will work with our monitor as this is not a cable we produce. This is a question for the cable manufacturer. ^CP
