i hope you can help me out a bit. Im new to this forum but i was around at the german hifi-forum for allready 12 years and also on the british avforums. So i hope im not a complete noob
I googled for a few days but didnt find anything to answer my questions properly. Finally this thread seems to be an appropriate place with allready pretty good informations in my direction.
So last week i bought a LG 55e6 as it was a good deal and the 55e7 lacks 3D support (which i really use very often) and only has minor advantages in brightness and processing. Lets hope for great 2018 sets
with HDMI 2.1, VRR, HFR, HDR10+ etc.
. All in all im very happy and only have minor to non banding on my set and no problems at all with the 3D being perfect. By the way the perfect banding test with real life content in near black situation is the movie Hacksaw Ridge on UHD bluray from 1:48:30 onwards (night shots with fog and smoke in the background). This is the only situation till now where i could see banding with real life content. Soccer and other sports with panning shots seem to be no problem. Would be interesting to know if you see banding in this Hacksaw scene on your sets too!?
So to come back to the main topic my problem right now with the 55e6 is that im really confused wich is the correct setting in NVIDIA drivers and on the TV espacially with watching movies in PDVD17.
First of all i got a Nvidia GTX 1070 with driver 382.33, Windows 10 64bit version 1703 (build 15063.332), PowerDVD17 and of course i set HDMI input to PC and activated HDR deep color on the input the PC is hooked up to.
As long as i have no 4k UHD bluray drive for my pc and so won't watch any HDR content but a lot of standard bluray and play a few games i thought the best was to set the Nvidia control panel to (RGB/8bit/rgb range limited which means 16-235)!? To match that RGB limited range i set the TVs black level to the low setting. I hope this is correct PC limited = TV low and PC full = TV high?
On desktop and games the black level with my TVs settings (oled light 70/contrast 75/brightness 51 to maintain 0 mll) seems to be fine like this.
But if i watch a movie in PDVD17 now the blacks are grey and i have to lower the TVs brightness to 42 to have black beeing black again. This cant be normal? As far as i know from google nearly everyone has their brightness set to 51 as optimal setting because it maintains 0mll for black and reduces black crush form which 2016 oleds suffer in general!?
It behaves exactly the same when i set the Nvidia control panel to (Ycbcr 4:4:4/ which is allways limited). Desktop and games seem to be fine with same problems in PDVD17 with movies.
If i select (Ycbcr 4:2:2 or 4:2:0/ limited) in Nvidia control panel games seem to have color problems. For example flickering sky in GTA 5. Blacks in PDVD17 seem to be black now perhaps too black. As i said i know the LG 2016 panels suffer from black crush in general and there are a lot of discussion from calibrators how to reduce it at least a bit. But if i use the AVSHD test disc with PDVD17 in this setting and view the brightness pattern, is it normal that i can only see the flashing from 20 onwards with TVs brightness set to 51? With brightness set to 55 i can see flashing form 18 onwards perhaps barely 17 but im loosing 0 mll for black. Is this the generally known black crush or is there another problem?
If i select (RGB/ full range 1-255) in the Nvidia control panel and of course set the TVs black level to high to match it, colors seem to be great in games and blacks seem to be black in PDVD17. Again blacks seem to be crushed a bit. In the AVS brightnes pattern i can only see flashing from 20 onwards again with brightnes of 51. Its again better with brightnes of 55 but again im loosing 0 mll black.
I am confused which is the right setting to watch movies with PDVD17 and if there is a software problem with PDVD17 or windows? I hope no hardware issues? I really hope someone can help me out. And also tell me if you had the same problems!? I put all my hopes in you guys!
Greetings from Germany! I hope my english is OK
