Initial follow-up on that LG OLED screen.
Initial out of the box picture settings aren't great. While at first the contrast ratio and true black blow you away, this set demands proper calibration (though the included cinema, APS, and expert settings come decently close). Furthermore, to fully eliminate extra processing on the signal, you'll need to configure your input as a PC.
Post-calibration its easily the best picture I've ever seen, but its not without its flaws, so lets start there.
* Motion judder on 24 fps material. Movies will have a bit of judder unless you use the "true motion" settings. Thankfully, these are user adjustable, and you can get a setting that eliminates the judder and doesn't dip into soap opera territory.
* Pixel consistency - at very, very dark colors (just above full black) my display exhibits a bit of inconsistency manifesting as a vertical bar slightly lighter in color just right of center. This isn't a deal breaker because the conditions under which it manifests have been extremely rare.
Now for gaming purposes, things are a bit interesting. Using any non-game mode picture setting results in unacceptable input lag. Using the aforementioned PC configuration helps, but I still found that game mode gave by far the best performance. The rub here is that game mode does not offer near as much flexibility in calibration as the excellent "expert mode" which offers full 20 point adjustment as an option. While I was able to very closely match the game mode setting to the calibrated expert setting, the lack of 20 point adjustment in game mode means that colors retain a very, very faint green tint in certain ranges. However, I found this only really to be noticeable in comparison to the calibrated "expert mode" settings, and the overall picture is still leaps and bounds beyond anything else. I'd also feel extremely comfortable using the PC input / game mode settings with my computer.
Actually, if LG made a sub-27 inch 1080p OLED display I'd buy it in a heart-beat for my PC. While I assumed GSYNC would be my next monitor upgrade, I don't know that I can live without those inky blacks and brilliant contrast.
