And the image I linked looks fine on a cheap $50 tablet and an iPad, so it's not compression.
Edit: Just tried the tool and it looks even worse. I get better results using the built-in tool in Windows to adjust the gamma, but still get weird looking pixel distortion/banding on the image linked regardless.
Windows calibration tool has terrible images to adjust the gamma with. Quick gamma is much better and it works excellent once you figure out how to use it.
Again as i already laid out previously, and thoroughly, Ideally you should use the larger downloadable only
non sRGB embedded gamma image from Lagom. The one that looks the same one used in Quick Gamma, because it is just bigger and easier to read. The more you use it eventually you will start to get the idea and feel for it.
It's also much better than Windows calibration tool because you can make a gamma profile and see what's going on in real time right on your desktop or across multiple images, or windows UI, your task bar ect, Things you know what they are supposed to look like. You can use perhaps an abnormally bad compressed image if you want just to see how much it is masking. For example this one. https://i.imgur.com/aARjBza.jpg
Even at it's best you should still see some pixelation in this image if you are viewing the image dead straight on ( See bottom of post for Viewing Angle Requirements, and then this image looks nearly perfect ).
When you press "ok" Quick Gamma automatically installs the profile for you, And if it needs a small tweak you can load up the program again and it will retain the RGB "numbers" / settings you have just last used, use a txt file and keep notes. The tool is good. But only as good as the user. The Numbers Don't mean anything. They are not the "Gamma" you are setting, they are offsets to whatever your gamma actually is. So pay not real attention to that, pay attention to the charts and images you will be using. Which SHOULD include all the gradients i posted. If you are not using ALL of this stuff together, you aren't doing it thoroughly and you will never get it a good as it can be.
So that's why Windows Calibration tool is crap.
You can also make a dozen .icc gamma profiles and switch between them all in windows color management and see exactly what it is doing and compare them. Though the effect is subtle. and you really need to know what you are looking at. If you don't understand what you are doing, then you are aimlessly flailing and never getting anything accomplished going in circles.Also very important.
When you do this. DO NOT have any other custom profiles loaded. Have Windows default sRGB profile loaded, which is basically like nothing at all, or else you are just "adding" too the last profile you loaded and then when you press "ok" It installs the new one, unloads the other, and now you are looking at something different.
I already posted all this stuff already in that huge post with step by step instruction, wasting my time. I can only assume you read it already and followed those directions right..lel...
Anyway it takes some time and patience, and if you think you are going to whip it up in Windows Calibration tool perfectly you are kidding yourself. Btw i been using Quick Gamma here and there for like over a decade and it still took me a few nights to get it right. So don't expect to do it in one try, or even multiple times till you get it exactly right.
If you fix the gamma the monitor looks great. and once you get it right you won't see any banding or artifacts unless the source is absolutely terrible. OR, or you didn't get it right.The final part of it is how you view the monitor.
It is basically part of using this monitor. And that is viewing the panel from slightly below. ( if you want the darker 2.2 gamma look)
Like if you game and lean back in your chair, your eye height should about at the bottom third of the panel. About 3 inches up from the bottom of the screen. You want to tweak the angle back ever so slightly maybe 1 degree, and have the height just right, and you will have about 2.2 gamma when you lean/sit back. If you like to sit straight at it, you will have about 2.1 gamma, which is still ok. really. This variance is fine for me. I chill in games and get 2.2 and more saturation and when i work in photoshop or whatever i sit up get 2.1 too see more dark detail.
To help you set your monitor angle you can *should" use the same Lagom gamma chart to help you get your monitor height and angle set to your seating. And it IS the source images that you use, some are worse than others and a low gamma will show this more. Your cheapo tablet and Iphone probably have at least 2.2 gamma if not even higher. Actual color is mostly irrelevant in this scenario. It's not, but it is, because the color is fine on the monitor. Color and Gamma being two different things. When you say the color is bad, what you are seeing as bad is the gamma. Not the value of rgb. Unless your monitor has some very serious issue different than everyone else that is complaining about this very same thing and using other peoples "COLOR" profiles to screw up their color even more.
Why do i say the angle and height is so important?
Because since on this monitor the gamma out of the box is really low, about 1.8. What that does is make the screen seem like it has less of a dark crush at the top than say another TN panel that has actual 2.2 gamma measured at the center. Or has a 2.2 OSD setting. So overall it seems like the panel has less of that contrast shift top to bottom, depending on the colors on your screen. But looks more washed out. On a 2.2 Gamma setting TN panel, if you have a Grey or Dark Browser skin for example. You will see that the address bar for example is crushed if it is dark grey, like mine is. The default gamma makes this hardly noticeable. But, then the bottom like my task bar is more washed out. Which i suspect they might have even done on purpose. As they also like to include those crap FPS settings and Dark Stabilizer ect on gaming monitors so they seem to think that gamers don't want contrast at all.
So what happens when you get closer to 2.2 on this panel then? Right. The top area is more crushed.
And by that is exactly how i know just by looking at it that it is closer to 2.2 gamma as when it's set up right and i lean back like that ( besides the fact the gamma charts proves it ) as that's what a tn panel with 2.2 gamma looks like on my dark skinned browser. My previous TN panel DID have a 2.2 gamma setting in it's OSD.
Willing to help, but i posted how to use it and set it up in that big post or was it 2 posts now, with all the gradients ect.. If you have any questions i didn't already cover exhaustively then ask. But if you didn't read any of it, then it's on you. Buy a calibrator, or new monitor.Edited by KGPrime - 10/18/17 at 2:34am
