Yes I checked but its grayed out so I will pick an unused input and change it.I will use all the suggestions and give it another go.Again your help was outstanding.I will get it right in the end thanks to the help.If that's what you used, that's fine. I'd still look at HDMI Black Level.
HDMI Black Level can only be changed when there's an active RGB signal. RGB Limited 10-bit ought to work fine, but you might prefer to use YCbCr 4:2:2 10-bit, as it avoids any RGB level inconsistency; it's what I use, with 1920x1080p60 for SDR and 3840x2160p24 for HDR.Yes I checked but its grayed out so I will pick an unused input and change it.I will use all the suggestions and give it another go.
Whow!! Yes I do warm up the tv before a CAL.All light modes are off (I have always tended to disable all unessential settings) Other you suggest I will try.Re Local dimming I set it for standard as I thought that if I set it to low then after back to standard being brighter would affect the picture?? I know that this can happen if I set it to high picture is YUK!!!.One more suggestion, warm up the TV by displaying real content for 30 minutes or so, before you calibrate.
For sure you don't want to use Local Dimming on High for SDR. I've previously measured my Q90R on both Low and Standard for SDR, and they measure the same, so it probably doesn't really matter whether you calibrate SDR on Low vs Standard. It's just that all the advice I've ever seen is to calibrate with dimming disabled if possible, otherwise set to lowest possible.Re Local dimming I set it for standard as I thought that if I set it to low then after back to standard being brighter would affect the picture?? I know that this can happen if I set it to high picture is YUK!!!.
Portrait doesn't offer demos that work with any real-world hardware. You can download a trial version, but it only uses simulated or virtual devices to show you how the program operates and what it looks like. You cannot make any real measurements. Their beta program is not a public one, and I'm pretty sure you have to have an existing paid license in order to participate.is there a beta version we could try?
HiRight, and even then you can't do it in Movie mode, hence the advice is to set it to Low as the best available option.
I'm kinda stumped for what else to suggest, sorry. Can you use the Manual Calibration workflow, selecting SDR, go the Grayscale Multipoint page, just do a Read Series using your calibrated settings (don't change anything), and post a screenshot of the results?Well I did another 6 cals with revised settings then made small changes before each cal to see if I can get a better calibration.This pic is the best I have got so far all 6 were about the same took hrs very slow
