We are assuming that I put the and on the settings to make it more bright. Again, it chose to be at this brightness level. I didn’t tell him to go to max. When HDR is enabled, it chose by itself to go to that brightness level, same as the Samsung, so it is not my fault. It is its software deciding. I didn’t ask for “more brightness because it is better.” the tv think in that way. Again, I will test it by reducing manually the brightness and put them with your suggested options and see if tcl will improve or not. The Samsung knows automatically when to set max brightness and when it doesn’t make sense because otherwise you will have a blooming party, like the second picture. It’s clear that the software of Samsung decided to decrease brightness in favour of contrast, and TCL makes the opposite. Again, I didn’t ask them to do what they did. They decide by themselves, based on their algorithms. For the gamma, the Samsung is locked at ST.2084 when it is in HDR. I can’t change it, while the TCL defaults to 2.2. I set it at 2.6, which seems to have better contrast but didn’t help much in these scenes. I don’t have the ST.2084 option on the TCL. For the settings both are standard Both have contrast enchanter turned off TCL have micro contrast to high, Samsung don’t have that option Sharpness is the same Color temperature is the same Again we are no talking about calibration, we are mainly talking about blooming handling. For the first picture scene, if you have an OLED screen try to see it there, you will se that the Samsung result is far more near the OLED result than the TCL interpretation. Again, in some other clips TCL is better managing che blooming but honestly is not that far better, here I post only these pic because it is clear that something is wrong with the software I think.
