Anyone using this new display yet?
http://www.lg.com/us/monitors/lg-27GK75 ... ng-monitor
Just ordered it, hope I'll get my hands on it on weekend or monday.
Picture on LG's off.site displays OSD: blur reduction simultaneously on with freesync. An error, probably?
I dont have an AMD graphics card to test freesync, anyway.
UPDATE Nov 2018: Settings for clearest 240Hz blur reduction mode on LG27GK750F-B monitor
Optimal/stable VT 1304 240hz resolution:
It is an overclocked mode, but it is fully safe to use it. It may result in minor display instability: sometimes, depending on how often you open the OSD, display loses sync and goes blackscreen and back on. It may happen once a 2-3 days, may once a 2 weeks. The more you open OSD, the more often these black screens may occur. Easy fix: power cycle the monitor (via joystick button). After the powercycle, the new 2days-2weeks cycle begun. Only happens with high VT like 1300+.
Workaround for frameskipping bug/buffering out of order/stuttering-juddering:
In CRU under extension blocks find a 240hz resolution. By default its Actual Refresh rate is 239,759hz or 239,764hz or may be other number depending on your system, GPU, driver etc. You need to round it and get Actual refresh rate number exactly 239,760. Note that this refreshrate is also stated in user's manual. VT1304 resolution above is already 239,760.
You also may use lower values like 1182-1184 (only 2-4 above default 1180), the point is to get exact 239,760 if it is not exact at defaults.
Service menu: viewtopic.php?f=2&t=4422 , no useful options found though.
"Optimal" settings: I stick with Gamma mode 4, default contrast and black equalizer, 45 brightness, Fast overdrive, MBR on full-time (yes I love blur reduction and CRT-like look!). Personally I found default colors fine enough, but R-G-B are also tweakable.
ICC profile is installed with display INF: http://gscs-b2c.lge.com/downloadFile?fi ... iLocE7WGOw
How to enable ICC profile: http://www.tftcentral.co.uk/articles/ic ... tm#install
Presets: Gamer 1 and Gamer 2 are the only usable profiles, they are fully adjustable. It's not recommended to use any other presets like FPS/RTS etc.
For minimal input lag make sure you choose "Original" scaling mode under Aspect ratio settings. Default is Full wide, and it is like ~1full frame slower then Original! So if you dont absolutely have to, always choose Original mode!
There is no advertised "Dynamic action sync" option found, but in Original mode this display goes on par with best other 240hz screens with 4,5-5,0ms of total input delay
Freesync and Motion blur reduction dont work together, and I have an Nvidia card, so no Freesync experience to share here.
