I am using my Q900A Soundbar with a 50" Samsung QN90A Neo QLED 4K TV. If yr looking for an awesome sounding, Surround Sound Speaker System thats has Dolby Atmos, Dolby True HD Sound, DTS:X with Q SYMPHONY and Alexa without any Sound Compression Compromise at all and a true 7.1.2 system + Sub Woofer + Optional Rear Wireless Speakers that's easy to set up and can handle lots of Power and Volume with crystal clear sound in all types of music this is it! I have been a surround sound system with speakers person until now and to be honest I was in doubt that a single Soundbar could even match the same sound quality and power of a separate surround speaker system and do a better job than separate speakers in my lounge. But after setting it up and testing it out, this Samsung HW-Q900A 7.1.2 speaker system with Sub-Woofer, even without the 2 Optional Wireless Rear Speakers, just blew me away and I am being serious. I was so surprised at the sheer Volume and Clarity thats comes out of this amazing Soundbar that I will never be going back to separate speaker systems again. I have a friend who is a pure gamer and he wasn't that impressed when he heard I was getting a new soundbar, that was until the day he came over and played his games online for 5hrs with my Q900A Soundbar and NEO 50" 4K TV in game mode and he walked away hrs later 100% convinced that these new Samsung Soundbars are the real deal, He told me that the sound of his games actually blew his own separate speakers away in all areas of his games, specifically he said in the surround sounds you don't normally take notice of or hear most times and he was impressed with the sheer volume ! :D That's the Power and Technology of Dolby TrueHD and Dolby Atmos coming in to play. Set Up was fast and easy, and the remote control handles all the adjustments when you need to make any. I have my TV set up with the eARC and use the TV sound and Soundbar at the same time which gives you a much fuller sound when listening to the TV or watching great Movies. If you want the Best True UN-compressed sound you can get from a Soundbar make sure you go with the a HDMI 2.1 cable with "eARC." Look for “HDMI Ultra High Speed” with eARC on the cable box and if it's not there ask the retailer for verified confirmation before you buy it. eARC stands for "Enhanced Audio Return Channel" and it is the newer version of the ARC standard. Side Note: All the HDMI Cables talked about here like the 2.0 and 2.1 will play yr 4k Video and TV no problems at all, we are mainly talking about the difference in sound quality when using the different HDMI Cables versions ok. The only difference you will encounter is the Refresh Rates of yr TV, the normal average is a 4K of 60Hz and for the NEO TVs they are 120Hz. Current HDMI 2.0 resolution and refresh rate capabilities cap out at 4K@60 fps or 8K@30 fps, while HDMI 2.1 can carry all the way up to 10K@120 fps. Is HDMI 2 and 2.1 the same regarding the Sound output? No!, the HDMI 2.1 upgrade represents a huge leap over HDMI 2.0 in data Transmission speed and volume and to get the true real sound thats what you need. HDMI 2.1 is now 48Gbps in bandwidth compared to v2.0 with only 18Gbps, which is a 135%+ increase in total bandwidth available for sound and that makes a huge difference to the end user. Now a std ARC HDMI cable will still work but that means it will have to compress the sound down to a level that gets the actual data volume down to 18Gbps, a level the HDMI 2.0 cable can handle. So that's why it's important to get the HDMI Cable version 2.1, with eARC. Whats the difference between Dolby True HD and Dolby Atmos? Dolby TrueHD is a true Lossless Audio Codec with support for up to 7.1 Audio Channels which is what the Q900A is and to really enjoy this, you must use a HDMI 2.1 Cable with eARC, it is the same std used with Blu-ray Discs. No major streaming platforms use it. Dolby Atmos is a 3D surround sound technology that allows sounds to be placed anywhere in a 3D environment. Dolby Atmos is really an extension of Dolby True HD, as mentioned before, is a lossless compression audio technology. In short, the sound will be almost the same as when it was first recorded. Usually, this type of sound format is used in Movie theaters. That is why we can notice even the faintest audio such as the blowing of wind or creaking of doors. Dolby TrueHD audio codec can replicate sounds from different ranges. In short, this audio format retains every bit of data from its original file available before compression. This exponentially enhances the sound quality and data size thats why you need the HDMI 2.1 cables so it can handle the data size. Dolby Atmos is a surround-sound technology developed in 2012 that expanded the capabilities of the existing 5.1 and 7.1 channel configurations. Dolby Atmos offers an edge to the sound quality by adding height channels of audio. Also Dolby Atmos is used in two different audio codecs, Dolby Digital Plus where it is compressed/lossy and Dolby TrueHD where it is uncompressed/lossless. Does Dolby TrueHD Support Atmos? Yes, Dolby TrueHD supports Dolby Atmos. This audio codec can work with up to 7.1 audio channels utilizing lossless compression. Also, the TrueHD format support for up to 24-bit audio is very commendable. Note: If yr just after the Dolby Atmos sound only, then you can get by with the std HDMI 2.0 Cable with ARC and that will give you the Dolby Atmos sound. Fiber Optic or HDMI Cable 2.1 which is better? HDMI 2.1 and 2.0 is much better than any Fiber Optic cable because both the HDMI cables support higher bandwidth and speakers systems up to 7.1 which means better sound, because it doesn't need to be compressed so is true lossless sound, where as Fiber Optic Cables only support Dolby Digital and speakers up to 5.1. What is HDMI eARC mode? The eARC (Enhanced Audio Return Channel) enables you to transmit the original full resolution audio signal through an HDMI cable and reproduce the best sound without compromise. Is HDCP the same as ARC? HDCP 2.2 is NOT the same as ARC. HDCP 2.2 is a technology that protects ultra high definition digital content from being copied. ARC is an HDMI feature that allows you to streamline your setup through one cable for external audio devices. Digital Digital Rights Management (DRM) is technology that enables online video and audio services to enforce that the content they provide is used in accordance with their requirements and Not pirated. We are all required by Law to have and use this technology regardless of what equipment we use. Sorry this review was so long, but I tried to Answer as many Questions as possible, the ones people have being asking me the most over last few months and I hope this has helped you make yr decision on whether to get a new sound bar or not and my answer is a very simple Yes as I absolutely love my soundbar. I have one complaint, small though it is I want to mention it, can you please in future put the sound display dial on the front of the soundbar instead of the top because I have to get up each time to check the settings. Why you would do that I am not sure. But overall I can live with that for the pure sound experience.
