Ok this is for those watching broadcast media and want a better experience. I watched GOT season premiere and I saw what everyone else saw as far as banding goes. There is only so much you can do to reduce the severity of it.
1. Use Calibrated Dark. By using a lower backlight setting, you are reducing the space between banded colors, effectively making it less visable. The higher your backlight, the more visible. I used 15 for watching GOT in a dark room. If you run into crushed black issues(everything looks too dark), then #2 can help.
2. Set the correct brightness level. Even though a lot of these displays the default is the right setting, sometimes you may need to make small adjustments. Go to the following link to set brightness.
Make sure you are sitting at your normal sitting position while you adjust this. Do not stand close to the display or at an off-angle. Adjust brightness up or down until 16 becomes invisible, but 17 is visible. If you can't, it's always better to see 17 at the cost of seeing a little bit of 16 than it is to not see 17 at all.
3. Set your contrast as well with the following link.
Make sure you can see 234 and not 235. If you can't, it's always better to see both than it is to not see 234.
4. Check brightness again. Check contrast again. Until you make no more adjustments. Then go to 5.
5. Adjust sharpness. For me I usually leave it at 0 for most content, but some broadcast media may need a nudge here. I do not recommend going over 10 here.
6. Get a professional calibration. Even though there are a lot of posted settings by some of us, it will not be perfect as no display is exactly alike. Even if it's the same model/size.
