Rated 5 out of 5 by from Great Monitor - but no where to be found! This is the best monitor I ever had. Bought it from Costco about 3 years ago. Wanted to buy another one, but unfortunately it was discontinued!

Rated 5 out of 5 by from The picture on this monitor is awesome. Costco had this on sale and the resolution was higher than my other monitor. Thought I'd give it a try. I'm glad I did.

Do the HDMI ports support the 3840 x 2160 display @ 60 Hz?

Asked by: ChamCham
That resolution is not supported over HDMI higher than 30 Hz, as far as I can tell. It does reach 59/60 Hz with the DisplayPort input, though.

Can this monitor be mounted on a twin monitor VESA stand?

Asked by: 1ngIT
The LG 27" Class 4K UHD IPS LED Monitor (27" Diagonal), Model # 27UD59-B is a VESA® compliant monitor that has a VESA® Wall Mount Interface pattern of 100 x 100 mm. ITs W x H x D dimensions are 24.9" x 14.8" x 2.4". If your twin monitor VESA® stand supports that VESA® Wall Mount Interface pattern then it can be used to mount the monitor. If you intend to mount two of these monitors, check the dimensions to make sure that your twin monitor VESA® stand will accommodate two monitors with those dimensions...^IFV

Hi there, Is this model (27UD59) proper for graphic design? Or you suggest another model? Thanks.

Asked by: mohayeji
That will depend on what your criteria is for a monitor that you need for what type of graphic design work you're doing. The LG 27" Class 4K UHD IPS LED Monitor (27" Diagonal), Model # 27UD59-B is an AH-IPS monitor so unlike monitors with TN panels which have a restricted viewing angle, especially vertically and exhibit contrast and color shift issues, AH-IPS (Advanced High-Performance IPS) monitors have wider viewing angles and can reach contrast ratios of up to 1000:1 - 1100:1. They produce more stable images with less contrast/color shifts across the panel and are free from off-center contrast shifts when viewed from an angle. The 27UD59-B is a 10-bit ((8bit + A-FRC) panel that covers 72% of the NTSC Color Gamut (CIE 1931) and about 99% of the sRGB Color Gamut. It has a resolution of 3840 x 2160 which is ideal if you're doing highly detailed work. It has a Pixel Pitch of 0.1554mm x 0.1554mm and a pixel density of 163 ppi, a Brightness of 250 cd/m2 and a Contrast Ratio of 1000:1 with a horizontal and vertical viewing angle of 178˚. The stand is not height adjustable, but you can tilt the monitor forward by 2˚ or backward by 15˚...^IFV

What is the difference in the 27UD58 and the 27UD60 monitor

Asked by: Travdaddy
There is the 58, 59 and 60 models. The 58 has a much better stand that allows for vertical viewing, tilt and swivel. The 59 and 60 are the same except for the release date or to the stores for which they are sent.
