Hey guys,
Im running windows 7 with madvr and mpc hc, and lately i notice when watching HDR content ( which is working fine on win7 ) im getting hdmi sparkles when sending signal through AVR receiver ( anthem mrx720 ), and its only visible on really dark moments and only on HDR content, my tv is LG E6 OLED. What i notice though, when nvidia display is set to RGB 8bit full range then i get those hdmi sparkles but when i see display to either 4:2:0 or 4:2:2 8-10-12bits sparkles are gone when signal is send through receiver, when i send it directly to TV from PC in RGB full im not getting any sparkles but the picture is not as dark and colorful as send through AVR. So im just confused what is best thing to do strictly for watching movie content : shall i set display to Ycbcr or RGB 8bit full range ? i want to know what settings should i use to experience HDR movie or any movie in their best - how its meant to be designed to be displayed. Hope this make sense. Btw changing my AVR input on tv to PC mode fixes the sparkles issue, but like i said the movie is not as black and saturated as without pc mode Last edited by maxkolonko123; 16th May 2020 at 09:13. |

What if you set nvidia to YCbCr 444 8 bit?
The "not as black and saturated" sounds like your TV is in limited range (black level set to 'low') but you are sending it full range. Maybe your AVR does a bad full -> limited conversion so you get sparkles? You do not want your AVR to be modifying the video signal...

Yes my TV black level is set to 'low' ( on PC mode tv ) but when i change it to high or auto then black is brighter then on low setting. When i switch my PC mode to hdmi icon on TV which switches off PC mode then blakc levels are set to high, but picture look same as black level set on low in PC mode --> actually when i went into options on TV when PC mode is off black level are set to low too which is not as " black " when i did put it on High black went more black but sparkles came out too I meant when i send signal to TV through AVR then black is more black if it makes sense, the not as black is when i send signal directly to TV from PC. I dont know if avr is modifying signal though cause there is no video processing options in Anthem AVR so to me looks like nothing can be switched on or off. Setting : YCbCr 444 8 bit shall i set when sending signal directly to TV or AVR? I've set YCBCr 444 and my desktop looks washed and brighter probably due to limited range in this mode, but movie looks like would be played in RGB full range just with Low level of blacks set on TV. So im just curious if its just me thinking the blacker black is how its movie meant to be designed ? or is just me and cause im adding extra black by settings level on TV it just crashes signal cause movie not meant be like this ? hope this makes sense Last edited by maxkolonko123; 16th May 2020 at 10:22. |

Set at Limited in Displaycal and GPU and seems worse.
I have the TV set in Game mode at the moment as it was the only 1 to give me 4:4:4, will try Monitor after, but things still look a mess ? https://filebin.net/qbgx5zzta0y6qfmq I have selected Monitor mode, and found I had been selecting full in Displaycal, as If I set Auto, I get this warming. https://imgur.com/a/XVSrPqo

Might be worth looking at this thread:
https://www.avforums.com/threads/phi...2200309/page-2 Like I said, I believe these sets are Limited Range, same as mine.

@madjock
you have to take this slowly. if the GPU is set to limited you should not use limited range pattern because windows runs in full range always and the GPU fixes this mismatch so the GPU expect full range. your monitor mode seems to be limited range just as oldpainlesskodi pointed out. so you need your GPU at limited range so 0-16 are not clipped (that'S about pattern not videos). |

TRY monitor mode, check that superfluous post processing is disabled in advanced settings things like dynamic contrast. MAKE SURE you've set OPTIMAL mode on hdmi 2 or hdmi 3. https://imgur.com/a/eNmZwok Make sure to UNPLUG and Replug hdmi cable to GPU, let it redetect. THEN SET the GPU settings to rgb 444 Full range. THEN run the measurement as set as before, ignore warning messages, what did you click on to get that message.

The HDMI selections is basically for UHD and I have had that selected since I got the TV.
Monitor mode only gives you Brightness/Gamma and Colour. There is no indication what Gamma you select in any option it is a scale of 0-4 in all modes. Monitor mode gives me good readings in Lagom LCD maybe the blacks not all the way but not bad and Whites are good. The warning comes up on initial calibration when set at Auto, if you select Full in DisplayCal it goes away, but I did not know if that was part of the problem. I have also been adjusting the colours to set the initial calibration up as in the red/green/blue markers ? Does this have to be done ?

Take a reading, post the HTML, it takes 2 minutes, and I can tell you what's happening.
You telling me the blacks are "not all the way", it's hard to help given that kind of information.

Haha OK. The kids have the TV at the moment. Will try and get near it in the morning. The top row of blacks were missing if I remember right.

The latest Tests
Game mode seems the best as I get 4:4:4, set GPU at Limited after various testing and agree it must be limited it does not matter what settings are changed. Both HTMLs uploaded one unmodified which shows colours are bad now ? All I am doing colour wise is adjusting RGB till the sliders match up. https://filebin.net/a01biib30a8vlh4h

you lost 500 CR just from max brightness.
set the color temp pre calibration to very warm or warm. reset the RGB settings after that use the interactive measurement and make sure you get the bar adjusted if you have to do huge changes to the RGB setting just stop it a deltae 2 is fine the CR lost should be to big. else you should be fine if you want ~170 nits and i guess BT 1886 gamma instead of 2.4. |

CR looks fine if you want 300+ nits than this is fine.
if you want to use madVR HDR tone mapping you should create 2ed 3D LUT from the same reading with gamma 2.2 or better with native gamut and DCI D65 or bt 2020 as source. if you only care about SDR you are done. |

Did that. All good. Thank you everyone for the help. Does running a longer calibration improve anything ?

Understood. I guess I am a little underwhelmed by it all, I guess I feel better that I will have more realistic colours and It will take my eyes some time to get used to the different picture.
It is what it is I guess.
