I've joined the forums in the hopes of getting some advice on my quest to calibrate my Samsung KS7000 HDTV.
I'd first like to bring you up to speed on what I've been doing, and I'd love some feedback to find out if I'm on the right track or completely wrong.
I purchased a SpyderX Elite a couple of weeks ago, I know it's not the best but it was in a big sale on Amazon and I think it's fine for me, I don't do any colour critical work, I just want to get the most out of my equipment in terms of colour accuracy, without spending too much. I calibrated my PC monitor with no issues, the software took care of everything and I'm happy with the results, but I'd like to calibrate my TV too.
I tried HCFR and was absolutely overwhelmed, plus it required unsigned drivers for my probe and I wasn't happy doing that. I came across ColourspaceZRO on AVS Forums forums and decided to email and ask a few questions, Ted gave me a few options and I decided that ColourspaceZRO and Ted's Calibration DVD files loaded on to a USB stick and plugged into my Xbox/TV would be the best solution for me.
I used the Pre-Calibration Tools video to set my brightness to 45, and my contrast to 100 (even at 100, I could see whiter than white?), I chose Rec709, legal range in ColourspaceZRO and started measuring.
I measured black, white, and 100% RBG values, I measured a grey scale in 20 steps that I'm assuming increased in 5% increments though I have no confirmation of this. I also found some 100% cyan, magenta and yellow patches in the files that I measured. I went back, and started using the TV controls to set a custom colour space, measuring the RGB CYM, trying to get the dots to align as close as I could get them, then counted to the 6th grey patch (assuming this is 30%) and adjusted the 2 point white balance RGB offset to match what ColourspaceZRO was telling me it should be, and then to 70% grey and tried to match this but couldn't get very close on this one as the chrominance was out and adjusting the green reduced the red, but adjusting the red decreased the green and I couldn't get close to the correct value. That's when I realised my gamma may be out, but I don't really understand how to set it correctly on the TV, as what I think is the gamma graph looks a bit like a x = y^2 curve, that's when I gave up and decided to ask here for help.
So my questions thus far are:
1/ Have I been doing things correctly, or as close to correctly with what I have?
2/ Does my TV showing flashing white bars above 235 even with my contrast on max mean that I should have set my range in ColourspaceZRO to extended rather than legal?
2/ How do I know what the correct gamma is, and how do I measure/test it?
3/ My measurements seem to change when the on screen controls are displayed, even though they're not near the centre of the screen, that's probably because it's a budget TV right?
4/ How should I go about doing colour space, white balance, and gamma adjustments for HDR mode? Apparently it can cover 90% of the DCI-P3 colour space, so I was going to do similar to what I've done, just get as close as I can with the TV controls and call it a day but, where can I find HDR patches?
5/ Are there any patches I can display on my TV via USB that would show the RGB values without me just guessing what they are? I assumed the grey scale showing 20 different shades of grey went up in 5% increments but, I literally have no idea if that's even correct, at best I'm guessing what the patch on the TV is showing and setting the sliders to match.
This is a screenshot I took the other night before giving up, I haven't done anything further, I don't know if it's going to help to show it but I'm including it just in case.
I know it's a long post but I just wanted to get everything on the table before asking for help, I appreciate any help that anyone can give, thank you.
TL;DR - help
