I know this may be a little late but I have had this display now for a couple of weeks. I live in Seattle and bought mine at Fry's in Renton WA. The US official retail price is $999 so DO NOT pay more than that as those are scalper prices from Korea and LG will likely not honor a warranty through purchases made that way.
Anyway, here is my review on Amazon.....😛
Ok, I have used many, many different kinds of displays. Matt screen, glossy, 30", 27", 24", surround with three 27", ect. This is THE best display I've ever used. I am aware of 4K and its ability and I believe this is way better than any 4K at the moment. Just my opinion. Most 4K runs at 30 Hz and its still in the birthing stage. Its true ability will take a couple of years to perfect.
First off, it's wide, very wide. It's the same aspect ratio of ultra-widescreen movies. Its the same height as a 27" 2560 X 1440 display with an additional 3-4 inches to each side--hence the 3440 resolution. It's light..about 1/2 the weight of my Apple cinema display being that all metal and glass and this being plastic. It comes per-calibrated but I had to tinker with the menu to get it to my preferences.
Its matt screened but hardly, and I mean HARDLY. I can see detailed reflections in it. The anti-glare coating is very, very light that I wouldn't even class it as matt. It's semi-glossy in my opinion with just enough matt to throw off harsh glares. It runs a smooth 60Hz via Display port and Thunderbolt and 50Hz via HDMI. I guess for hard-core gamers a 120Hz would be desirable but I could never tell any difference. Its plenty fast for me as well with a 5MS response time.
The real winner here for me is the back I/O ports. The thing has a built-in KVM switch and/or Thunderbolt dock. What I have is a brute of a PC and a late 2013 retina MacBook Pro. Both are plugged into the I/O on the back and both run native resolution and sound without any need for any KVM switch! Its built right into the menu on the display. Choose your input and the rear I/O does the magic. I am ONLY using the Thunderbolt port and cable running to my MacBook Pro. Nothing else. No USB, audio, nothing. I am using the display's USB "uplink" to plug into my PC, and then I plug in my only keyboard and only mouse in the back USB "In" ports on the back of the display. All I need to do is use the display's joystick menu controller and switch inputs and its works like a charm! USB data, audio, and display video are all carried over the single Thunderbolt cable to my Mac and the PC is controlled via the USB cables. Wow.
Totally awesome and immerse to the core. I have separate speakers for my PC and the audio from my Mac is passed into the displays speakers which are really not bad.
All in all, this display is what I've waited for years to obtain and it's here.
Thanks!
