    Hey guys I have read with Samsung TV’s the picture can be dim in 4K HDR, I’m noticing this as well with my settings. I have a 65” Samsung Q7. I have my settings in movie mode. Any advice on brightening the picture up? Otherwise I’m stuck going to 4K SDR. Thanks guys!!

    For a Samsung HDR TV that you want the image to be brighter I would recommend...

    Have the ambient lighting set to the highest point it would normally be while watching TV (or wait for daytime). Again this is for a brighter image not perfect calibration.

    UHD Color on for the HDMI port in use
    Special Viewing Mode - HDR+

    Find a brightness calibration image (THX Tune-up app has one for ease of AirPlaying it). Set the brightness correctly even if it requires you dropping it.

    At this point if the image still appears dark its probably because you are used to it being overly bright which is fine, there is a difference between calibrated and what you like.

    However to help prevent washing out the image if you still want it brighter find the "Dynamic Contrast" setting and increase it in steps. You should be able to make the image "pop" and keep it bright.

    Did it work though?

    Sometimes I wonder if I'm the only person here happy with the HDR setting turned on. Lol

    So far so good! I’m playing around with Spider-Man Homecoming. I never used the THX app, seemed to help a little and I increased the ambient lighting to the max, but shut off the motion sensors for light detection (off prior). It helped especially when I increased the contrast enhancer, that really seems to help with the Apple movies. Again thank you!! Really enjoying it a lot more now...you were a huge help!!

    Having the same exact issues on my Samsung TV. Menu looks dull in 4K HDR vs SDR.

    I turned my ambient light up to 20 and shut off the motion sensors after...prior to that it was at 0. I also put the contrast enhancer to low...may have to play with it for you like. Either low or high seemed fine...high was too much for my taste, but after that and playing for a minute with THX app I’m very happy with the results.

    Great advice, except HDR+ is for "upscaling" SDR content into HDR. It makes everything look yellow in my opinion and should definitely not be used for original HDR content.

    The brightness of the movie mode is definitely too dim for my taste.

    The menus are dim, however its intentional for some reason and doesn't effect the content.

    Here is a video I made so you can see what I'm talking about.



    I have auto exposure locked so what you see is what its actually doing. Notice how the screen saver comes up and then the brightness dramatically increases? Switching out of the screen saver dims it again just before switching back. You can see this with all the content too, for example if you watch a youtube video then double click home to bring up the multitasking it does the same thing.

    I'm not exactly sure why this is. It does the same thing when they are set to "light". This is something Apple can improve unless there is a reason for this on certain TVs (too bright) however if that is the case they should have a menu brightness setting.

    Device is brand new, on its first OS release. I'm confident we will see a lot of improvement.

    You are correct. I was about to post back to @Ramrod82 about this. I don't know if the TV was stuck in non HDR mode or if I had previously adjusted the settings however once I switched it back to Movie, the brightness did not change. I have a feeling something was stuck preventing the TV from going into is HDR profile and me switching to a special viewing mode and back "unstuck" it.

    I keep “HDR+ Mode” off sorry for the misunderstanding...agree with your statement, I have actually never turned that on. If it’s too yellow have you tried changing the color tone to your liking that usually gives a picture a yellow tint the warmer it is. For some reason Xbox and others adjust it to warm 2 automatically. I keep my at standard or sometimes cool...I also agree the with above comment and noticed the screen saver and change in image....with this being the first release in its software/OS I’m sure it will get addressed for now this is the best I can do.

    Ahh this makes so much sense, it happens so fast I never realized it before. Thanks for posting the video. Was concerned other content was staying dull as well. Will be interesting to see future software enhancements.
