Rated 5 out of 5 by from 21:9 and no defects Bought this at Fry's and I don;t regret it one bit. No pixel flaws and great screen real estate. Replaced a 27" 2560 x 1440 monitor and the extra pixels are worth the $$$. Not quite 4K but close enough. The curved screen is fine as long as you do not have a bright lighted area behind you. Used for gaming and work.

Rated 5 out of 5 by from Perfect ultrawide monitor I've been using this monitor for almost a month now, and the experience has been fantastic.

Rated 5 out of 5 by from Highly Recommended Worked for years in front of a pair of 1920x1200 displays and was reluctant to move to an ultra-wide display because I naively thought that the physical dimensions of the 34UC88 seemed to be twice the width of a traditional 1920x1080 display and I thought I would be losing usable screen real estate by moving to the 34UC88. Having made the switch last month, I now know that I should have made the switch long ago — particularly at this price point (versus 38" widescreen models). The substantially higher resolution means that I have encountered no loss of usable real estate, and the benefit of a large, ultra-wide display when I have to work through enormous spreadsheets has been invaluable. The appearance of the 34UC88 was cleaner and more attractive than other displays I considered, and the matte-finish screen is easy to stare at throughout the workday and beyond. My MacBook Pro was able to automatically render the 34UC88's default resolution (via either HDMI or DisplayPort), and the on-screen menu accessed by the power-button-joystick is intuitive and easy to use. I have since purchased another 34UC88 for my wife's home office, and we are both very pleased.

Rated 5 out of 5 by from Great monitor at a great price I researched large monitors for quite a while and landed on this one. It has been excellent so far. There are only 2 suggestions. They should make the directions for connections clearer. Also there is no where in any of the descriptions that list speakers but this monitor has some nice ones for built ins.

Rated 5 out of 5 by from No Regrets I bought this almost on a whim - I'd been looking for an ultrawide for a while and finally pulled the trigger on buying one. It's fantastic. The picture is phenomenal, the curve is easy on the eyes, and I even regained about 40% of my desk now that I only have one monitor.

Can I set quad screen and assign hdmi 1 to the screen 1, hdmi 2 to the screen 2 ? Works that way?

Asked by: Josias
I apologize, but no; according to the chart on page 25 of your owner’s manual, it is not possible to use both HDMI ports, at the same time, for the Picture By Picture (PBP) functions.
