Great suggestions on how to deal with it! So, I *think* that adjustment layers are applied to an image in Photoshop as somewhat of a preview.

Take a look at each of your channels.

The presence of these dark patches is also known as dirty screen effect. For best results with color depth, you should get a TV that is capable of displaying 10-bit color, and then play HDR media on that TV. Likewise, saving image files as a TIFF, or minimally compressed JPEG, will keep the maximum number of tones available, whereas a highly compressed JPEG will eliminate subtle differences between colors and introduce that terrible stair-stepped, chunky banding. Vertical banding may be noticed while viewing content on the TV as well as by running some test videos on Youtube.

More detailed color is one of the promises of HDR media, so it’s worth getting a TV that performs well on this test if you’re interested in HDR. curious to know what you guys thing about this and if of anyone ever did it this way! To remove banding in an image file, first try to upsize from an 8-bit file to a 16-bit file. in edge-lit TVs where LEDs are placed only along the edges). For this test, we determine a TV’s maximum color depth, photograph a gradient test image displayed at that color depth, and then assign a score based on how well the test image was reproduced. Here are five we took on the road. Then there is floating point and integer file formats and that’s where all this becomes unpleasantly complicated. One other source for banding I have noticed can come from adjustment layers, particularly if they have a layer mask with a smooth gradient of some kind. However, light may not be distributed uniformly across the screen due to a number of different reasons. I personally use a totally different method, witch for me works very well as I don’t need any extra processing step of the image. It will render better results this way as RAW files have much more information and values are unclamped.

It also depends on personal preferences, as some people prefer a brighter or darker image. You should be able to get a replacement TV in case it can’t be repaired. Compare a TV that performed well in this area (above-left) with a TV that performed poorly in this area (above-right). In an image with evident banding, it’s as if what should be a smooth line on a graph is actually stair-stepped, and we’re able to see each of those transitions from one tone to another right there in the picture. After determining the highest possible color depth of the TV (see test below), we take a photo of the TV’s screen while it is displaying our gradient test image at that color depth. The screen’s bit depth is not high enough to follow the detailed instructions of a high-bit-depth signal. Are thin-screen TVs more fragile than rear-projection or CRT TVs?
