OK thanks. Don't know what Dolby atmos support is but I'll figure it out. One of the reviews on takealot was complaining about the sound?
I had the 55B8000 ULED and now have the 55Q8600 QLED. Both are excellent TVs, although the QLED is much better.
The sound on both of them has been perfectly fine for me, especially when watching movies which have Dolby Atmos. They have only 10w speakers but people expect them to be very loud like in previous TVs, but most people in today's time, all have sound bars which can connect to these TVs via Bluetooth, which obviously will improve the sound. Modern TVs are built around people having sound bars, but I'm quite happy with the sound of the TVs as is.
Getting one of these TVs will future-proof you later in future as they have the latest in features and tech i.e. Dolby Vision, Dolby Atmos, Dstv-now app preloaded ...
You asked if the B7100 would give you issues... I definitely don't think so... But the sound is also poor on that TV in the sense of it only having 10w speakers as well...
There are pros and cons on these TVs, you cannot find the perfect TVs in these price ranges, but they pretty darn good for the price they ask.
If you want best of the best at the moment, you should look at OLED TVs by LG or Samsung (although Samsung doesn't support Dolby Vision at all and doesn't appear to ever will) and be expected to pay well over 20k for anything.
Some things to note on the various models to perhaps help you.
•B7100•
Entry level UHD
HDR
Smart TV
Has DStv-Now, Netflix etc preloaded
Has very decent viewing angles ( TV can be watched while sitting at various angles in the room, and not just directly in front of it)
Sound isn't the greatest.
•B8000 ULED•
ULED technology
Over 1 billion colours
Wide colour gamut
HDR
Local dimming
700 Nits brightness.
Smart TV with same apps preloaded as stated above
Has 2.4Ghz as well as 5Ghz WiFi.
Bluetooth
Dolby Vision and Dolby Atmos
Sound is better than on the B7100 in my opinion
Very poor viewing angles. Colour washes out to a bright white if you watching from angles not in front of the TV.
•Q8600 QLED•
QLED technology
Quantum dot
Over 1 billion colours
Wide colour gamut
HDR
Local dimming (double the zones compared to the B8000)
1000 Nits brightness. The colour is insanely brilliant on this TV.
Smart TV with same apps preloaded as stated above
Has 2.4Ghz as well as 5Ghz WiFi.
Bluetooth
Dolby Vision and Dolby Atmos
Sound is better than on the B7100 in my opinion
Very decent viewing angles. Probably equal to the B7100, and much better than the B8000.
Low reflecting panel... So very ideal if placed in a very bright room or near a window.
Hope that helps.
I've attached a spec sheet I found online for you to view.
