Neowin member +mrk has posted this interesting LG 34UM95-P Ultra wide monitor review. Here's a taster:

Pros & Cons

+ Cinematic immersion, amazing for movies & supported PC gaming.
+ Uniform colours with no visible backlight bleed (not to be confused with IPS tinge which there is).
+ Gaming performance for me was just fine. I have never gamed on a 120Hz monitor but my gaming style in FPSes has adapted to the nature of IPS and I have no problem at staying in the top area of scoreboards in online FPS games like TF2.
+ The joystick button is genius, so easy to use and nice.
+ Visibly frameless front apart from the glossy bezel part at the bottom.
+ Can have a large browser window open AND a 1080P video beside it and you can enjoy both at the same time.
+ Hardware calibration means whatever you connect up via the other inputs you will benefit from the calibrated colours too.
+ Does not generate much heat. It's been on several hours and it's cooler than my U2713HM. I would say this is mostly down to the fact that this has a power brick so a lot of heat stays away from inside the monitor. The WLED backlight generates little to no heat.

- Glossy strip at the bottom of the screen is pointless and will only look poor over time as you wipe it. I've learnt this out already!
- Reader mode will disable Calibration mode but when you turn Reader mode off it won't turn Calibration mode back on.
- Enabling DisplayPort 1.2 in the OSD did cause random flickering for me even on the Windows desktop. Disabling it solved it. Visually I can't tell any different so maybe 1.2 mode isn't fully working yet I don't know. many others are reporting the same. Let's see if LG release a firmware update.
- Hardware LUT only usable via the LG software. True Color Finder stays running in the system tray. It uses 18MB of RAM only.
- No USB3 upstream cable supplied. I had to use my own.
- Only 1 USB3 downstream port, the other 2 are USB2 ports.

Will I miss dual screen? Yes and no. Yes because I liked having a 24" in vertical orientation and reading sites and magazines as they're supposed to. No because this looks way nicer and offers much more everywhere else.

Should someone else buy the LG instead of waiting for the Dell version? Interesting question. LG have marketed this display at image and video professionals/enthusiasts and the included hardware features benefit them clearly. I have a feeling Dell may not include some of those features in their version and we can definitely expect to see a higher price (I paid £830 for the LG). One thing is for certain, Dell's stands and RMA processes can't be beat.
