Here's some interesting tidbits that probably nobody knows.

SAMSUNG removed the HDR+ mode on 2019 sets but seems to have secretly disguised it in movie mode. When you turn on the dimming to high with contrast enhance OFF, the former hdr+ is now activated. Turning the backlight to 50 will actually darken the picture and give a weird effect to the screen. Lowering the backlight to 30 will brighten the image and lower the weird effect. Lowering under 30 the picture will continue to darken the picture. Turning contrast enhancer to low will deactivate this weird hdr+ effect and brighten the image back to normal. Even the cal day/night modes act the same way. (this is for SDR content only).

BONUS FACT:

I turned on HDR+ mode in the service menu. But the hdr+ mode does not act like the above mode or like it has in previous years. It's basically identical to standard mode now with slightly different set points and dimming algorithms. (by turning this mode back on which Samsung deactivated , the HDR+ option is in the settings menu under contrast enhancer like the 2018 tvs).


Edit: I should clarify. With HDR content, hdr+ is just like standard mode except it has less black crush baked into the presets,making it ever so slightly brighter.

What weird effect do you speak of? As I leave my backlight on 50, contrast 42, local dimming high & CE off, I've noticed no weird effect. Now If I put CE on low, I notice that bright highlights get clipped much easier, even with contrast at 42.

Can you get HDR+ to work with Q90R and a PC? If so, please explain how to setup.

Try putting the contrast at 50 and trying it. This is with movie mode and SDR correct?

Considering this TV. Mounting on a wall with no entertainment center below. How do I hide the one connect box, especially if I wanted to do a no gap wall mount?

I like a slightly darker screen since I use minimal lighting and watch most of TV in the evenings (and find plenty bright for daytime). I leave "Intelligent Mode" on and it must work well because it has never caused a noticeable concern.

I have set Adaptive Brightness, which seems to work well in brightening/dimming the screen in response to room ambient light levels. Except for one curious "quirk" - when I change input sources (doesn't matter from what to what), the new source will be very, very dark (unwatchable). In order to restore normalcy I have to turn off Adaptive Brightness then turn it on again, all is then well until I change sources again. This does not happen when Adaptive Brightness is turned off. I may just live with this, or I may turn it off and instead turn the backlight level up and down manually with the sun.

I guess this together with the CEC issue of not automatically turning on the receiver with the TV (it does turn it off) are just whimsical little "features" left for us to hunt by the Samsung engineers. But will they fix them when we find them?!

Anyone know any easier way to fix the elevated blacks other than a full picture reset? I have them again and don't feel like resetting the whole tv again.

I find myself having to do it like every 2 days. No idea what's going on.

I’ve never witnessed this elevated blacks issue. Actually, my set has been near flawless since day 1. I didn’t install the most recent firmware update though. I don’t think I will install another update unless it includes eARC. I’m satisfied with everything now and it would be a shame to break something with an update.

I don't have this problem even if I have done all the firmware updates (1325.1 now). The picture is so great now that I have found my settings.

Does the Q90 support Atmos through any of the built in apps? I didn't think Samsung did but someone on another forum is saying that Samsung has Atmos through Vudu on the built in app.

The Star Wars movies on Disney+ look incredible on this TV.

ohyeah32, I am getting Dolby Digital. I can't remember if it is through ARC, or if I hooked up an optical cable, though. I think it is ARC.

I’️m using the optical out on mine, never tried using ARC. All apps I use (Netflix, Hulu, Prime, Vudu, AppleTV+) all output 5.1 via the TVs optical out. Odd that this new Disney+ app only outputs 2.0 via optical.

Disney + is looking incredible on my 82 inch Q90R. However, I am getting stereo sound on my Sonos Playbar 5.1 setup.

No one has any info if this firmware has earc yet?

No offense to anyone that thinks a soundbar is a valid piece of home theater gear but damn... that's a moronic method to obtain 3D audio. Without real height speakers and full bandwidth, why even bother. I have already ruled out the current slate of Samsung's for purchase anyways so without real earc support I guess I can just put these to rest. oh well... I suppose LG is the only game in town now.
