Hisense AX5120G issue

I don't think Samsung is attempting an upmix to Dolby ATMOS or DTS-X. I think they employ what they term DSP (Digital Signal Processing) to create what they call Acoustic Beam Technology, but I don't think they apply this to the height channels. My current understanding is that phantom channels are created on each side of the center channel in front and the sampling of part of discrete channels is also used to mix in to create 9.1.2 from a 2.0, 5.1.2 or 7.1.2 signal in modes other than STANDARD, especially using ADAPTIVE. From exploded views Samsung has shown of the interior I only count 12 driven speakers and what look like three passive cone radiators. I don't care for this playing around with signals, especially since voice ends up in the surround channels. At the very least this should have been filtered out. I would prefer to hear only the real "intended" signals and therefore wish to get the STANDARD option working consistently.

"The Q900T automatically optimises sound to whatever you're watching so you get a true sound experience, just as it was intended."

This sounds like their claim for the ADAPTIVE sound mode. I don't think the manipulation in this and modes other that STANDARD creates what I think the intended true sound experience should be.

Here is a chart showing what I have been talking about. The Q900T couldn't do the rear ATMOS channels to achieve 7.1.4. The next bar released, the Q950T could do so since its rear speakers had added some upfiring drivers.

I contacted Hisense, but until they get back to me, I slammed together an ad hoc solution by rigging the subwoofer and rear surrounds to a cable with a power switch, so I can now switch them off when watching stereo or mono content. It’s not perfect, but it works. I hope you figure out a solution for your problem. มีวันที่ดี

It appears that we both have found at least a temporary solution to the problem. I found another review of the Q950T that describes the same fault I am finding with my Q900T. He also found that switching to the Standard mode doesn't always work properly, and had to toggle into another mode and then back again to get it into that mode correctly. He stated that he didn't like STANDARD because it was "too directional"....yes, I think not bunching the discrete signals together would have that effect.

I wanted to try another option, an app from Samsung called SmartThings that provides additional control. I hate phone apps in general as I have had trouble getting a high percentage of them to work. This one will not let me sign in, and sometimes a message says my browser is incompatible, even tough it is one listed that will work. I also can't sign into it on my Samsung TV on which it came already installed.

I wish you a good day as well.

I'm finding your Hisense soundbar to be interesting. Unlike mine it came with the rear speakers included. Hisense has marketed TVs here in Thailand for years, but not their soundbars.

BTW, did you see that Studio Canal is going to release "The Third Man" in 4K UHD September 18th in France? This is significant for me because I consider it to be the best film ever made.

Thanks for all your help, it means a lot. Hopefully you’ll find some sort of solution yourself. And yes, I did see The Third Man announcement, but I didn’t see the release date. It’s one of my favorite films as well, so it’s definitely going on my calendar.
