Rated 3 out of 5 by from Works ok but not 100% iMac Pro compatible Works ok but not 100% iMac Pro compatible, the screen resolution is fine but when the monitor is connected the iMac mouse pointer is jerky intermittently. It's a real killer and every time the monitor starts I get the message "(Caution) make sure to use a supplied mini display port and HDMI cable" but the iMac pro doesn't have a display port but it on the iMac pro supported monitor list??? I tried a USB-C to Display port and the monitor is not even recognised. Very frustrating indeed. Apparently its a common problem on further research????

Rated 1 out of 5 by from Total junk Bought it and when warranty was expired video board crapped. You did nothing for me so it went to recycle plant. I cannot afford to deal with manufacturers like LG

Rated 5 out of 5 by from LG won't disappoint Have had this tv for 5+ years. It's great, sleek and the picture quality and features are optimal for 2010. Consider this, all advanced features relevant to xbox one are compatible with this lg tv, even though the xbox was released years later. Lg products are competitively equal to other bands, and cheaper. They support all current generation features given the year of the product. I've never had a problem with my LGTV. It's served well and there has not needed to be any maintenance so far. The LG team knows quality as well as reasonable pricing on products.

Rated 4 out of 5 by from Almost Awesome it's now more than 6 months since i purchased the LG tv. it actually is far much better than my previous unit in terms of clarity and im spoilt for choice. i especially like the fact that the navigation is so simple yet precise. also the additional Bluetooth sound function is a plus. i however do have a couple of downside to it. the apps are limited (i wish they introduced KODI for this tv) also the storage is way way to small. i hope they introduce compatible 1tb disks that can be easily replaced, this will assist in strong downloaded movies and series to be viewed later and at leisure. this will also reduce the number of times that the apps have to stop in order for the tv to clear some space otherwise. i would highly recommend this to anyone.

What color setting do I make to view HDR color?

Hello, the 31MU97 does not have HDR (High-dynamic-range) but is a 4K monitor. The color settings are going to be person preference. ^AC

What monitor arm would I use with this monitor if I wanted to mount it on my desk?

Asked by: Freddy5825
The LG 31" Class 17:9 Digital Cinema 4K IPS LED Monitor (31" Diagonal), Model # 31MU97-B has a VESA Wall Mount Interface of 100 mm x 100 mm. That VESA Wall Mount Interface can be used for Wall Mount Brackets or Monitor Arms and it guarantees that if they are VESA Compliant, that they will fit provided they support the same Wall Mount Interface that the monitor has. So when you do a search for compatible desktop monitor arms, be sure to look for any that support that VESA Wall Mount Interface pattern...^IFV

The HDMI ports on this are version 1.4, not 2.0 correct? If so, can a 10 Bit color signal be transferred to this monitor using the unit's HDMI 1.4 port, coming from a Blackmagic Decklink card, which supports 10bit color export over HDMI (2.0)?
