Total PackageThe curve is great, no odd pixels, color is perfect. I could go on and on. Had it for a year now and barely light bleed. It is now my secondary monitor as I have the big boy 34uc79g as my first. Both are just great!

Asked by: Ppel
The LG 29" Class 21:9 UltraWide® Full HD IPS Curved LED Monitor (29" Diagonal), Model # 29UC88-B only has 2 x HDMI input ports on it. They do not support daisy chaining. Displayport 1.2 to Display Port 1.4 supports daisy chaining multiple monitors, but your graphics card must support it...^IFV
