Display Technology Comparison
The Samsung S90H uses OLED display technology. Each pixel produces its own light. This means perfect blacks because individual pixels can turn off completely. The contrast ratio is essentially infinite.
The Vizio M512a H6 is a soundbar and does not have a display. So this section focuses on what the Samsung S90H brings to the visual side of your setup.
The S90H supports OLED HDR+ with HDR10+ Adaptive and HDR10+ Gaming. Colors are rich and accurate thanks to Perceptional Color Mapping technology. The panel also features a Glare Free coating that reduces reflections in bright rooms.
4K resolution at 3840 x 2160 pixels ensures sharp detail. The 4K AI Upscaling Pro feature uses the NQ4 Gen3 processor to enhance lower resolution content. Standard HD content looks noticeably cleaner on this TV.
Audio Performance Head to Head
The Samsung S90H has a built in 2.1 channel speaker system with 40 watts of output. It supports Dolby Atmos, Object Tracking Sound Lite, and Adaptive Sound Pro. These features are good for a TV, but limited.
The Vizio M512a H6 is a dedicated audio system with 5.1.2 channels and 11 speakers. It outputs around 200 watts. The two upfiring speakers add height channels for Dolby Atmos content. The wireless subwoofer adds low end punch that no flat panel TV can match.
For movie watching, the Vizio soundbar wins clearly. Dialogue comes through a dedicated center channel. Rear speakers create true surround effects. The upfiring drivers add that overhead dimension for rain, helicopters, and other overhead audio cues.
For casual TV watching, the Samsung S90H speakers are perfectly adequate. The AI sound processing adjusts audio dynamically based on content type. But serious audio enthusiasts will want the Vizio soundbar or something similar.
Gaming Performance
The Samsung S90H is a gaming powerhouse. It supports a 165 Hz refresh rate through Motion Xcelerator. All four HDMI 2.1 ports support 4K at 165 Hz input. Variable Refresh Rate technology eliminates screen tearing.
The TV also supports both AMD FreeSync Premium Pro and NVIDIA G Sync. This makes it compatible with PC gaming rigs, PlayStation 5, and Xbox Series X. Input lag is very low, which is critical for competitive gaming.
The Vizio M512a H6 contributes to gaming through its Dolby Atmos and DTS:X decoding. Surround sound in games like Call of Duty or Forza helps you hear enemies and environmental cues from specific directions. The rear speakers make positional audio much more immersive.
Pairing both products gives gamers the best of both worlds. The S90H provides the stunning visuals and fast response. The Vizio soundbar delivers the immersive directional audio.
Smart Features and Connectivity
The Samsung S90H runs on Tizen Smart TV with the new One UI interface. It includes built in Bixby and Alexa voice assistants. Google Assistant works through compatible devices. The Samsung SmartThings app connects the TV to your smart home ecosystem.
The TV features Wi Fi 6E and Bluetooth 5.3 for fast wireless connectivity. It has four HDMI 2.1 ports, three USB A ports, one Ethernet port, and one optical audio output. Samsung Vision AI adds a local LLM assistant that runs on the TV itself.
The Vizio M512a H6 has simpler connectivity. It offers HDMI ARC, optical input, AUX input, USB port, and Bluetooth. There is no Wi Fi, no smart platform, and no app store. It does support voice assistants through external devices connected via AUX or Bluetooth.
The Samsung S90H clearly wins in smart features. The Vizio soundbar keeps things basic and focused on audio.
Build Quality and Design
The Samsung S90H is extremely thin at the top portion of the panel. The lower section houses the speakers and electronics. It looks premium on a wall or on its included stand feet. The overall weight is about 19.1 kg without the stand for the 65 inch model.
The TV uses a SolarCell remote that charges from ambient light. This eliminates the need for disposable batteries. The remote is slim, minimal, and easy to use.
The Vizio M512a H6 soundbar measures 36 inches wide. The main bar has a dark charcoal finish that blends well with most setups. The wireless subwoofer is compact and can sit beside or behind furniture. Build quality is solid for the price, though the satellite speakers feel somewhat lightweight.
Both products look clean and modern. The Samsung S90H has a more premium feel overall.
Price and Value Comparison
The Samsung S90H starts at $1,399.99 for the 42 inch model. The most popular 65 inch size costs $2,699.99. This is a significant investment, but you get flagship level OLED picture quality.
The Vizio M512a H6 typically sells between $300 and $400. For that price, you get a full 5.1.2 Dolby Atmos surround system. This is one of the best value soundbars on the market for Atmos support.
Combined, both products would cost around $3,000 to $3,100 for a complete home theater with a 65 inch OLED TV and 5.1.2 surround sound. That is a strong value for the experience you receive.
The Vizio soundbar offers exceptional value per dollar. The Samsung S90H offers premium value for an OLED TV in its class.
Who Should Buy the Samsung S90H?
The Samsung S90H OLED is ideal for movie enthusiasts who want deep blacks, vibrant colors, and HDR performance. OLED technology produces the most cinematic picture available in a consumer TV.
It is also perfect for gamers. The 165 Hz refresh rate, VRR support, FreeSync Premium Pro, and G Sync compatibility make it one of the best gaming TVs in 2026. Low input lag ensures responsive gameplay.
Buyers who want smart home integration will appreciate Samsung Vision AI, SmartThings, and the built in voice assistants. The TV connects easily to other Samsung devices and third party smart home products through Matter support.
If you watch TV in a bright living room, the Glare Free coating makes this OLED usable in daylight conditions.
Who Should Buy the Vizio M512a H6?
The Vizio M512a H6 is best for budget conscious buyers who want real Dolby Atmos surround sound. You get 5.1.2 channel audio with upfiring speakers for a fraction of what premium soundbars cost.
It is great for movie and TV show fans who want better audio than their TV speakers provide. The dedicated center channel improves dialogue clarity. The rear speakers add true surround effects. The subwoofer adds bass impact.
Gamers who want positional audio in first person shooters and adventure games will also benefit from this soundbar. Hearing footsteps behind you through dedicated rear speakers gives you a competitive edge.
This soundbar works well with any TV that has HDMI ARC or optical output. It pairs perfectly with the Samsung S90H through its eARC HDMI port.
Can You Use Both Together?
Yes, absolutely. The Samsung S90H and Vizio M512a H6 work together perfectly. Connect the soundbar to the TV’s eARC HDMI port for the best audio quality. This connection passes through lossless Dolby Atmos audio from streaming apps and Blu ray players.
The Samsung S90H will automatically detect the external soundbar. The TV’s built in speakers will turn off. All audio routes through the Vizio system.
You can still use the Samsung remote to control the soundbar volume through HDMI CEC (Anynet+). This means one remote handles both devices.
Pairing both creates a complete home theater system with premium OLED visuals and immersive 5.1.2 surround sound. This combination delivers a cinema like experience at home.
Final Verdict
The Samsung S90H OLED Vision AI Smart 4K TV and the Vizio M Series M512a H6 are not competitors. They are complementary products that serve different purposes. The Samsung handles the picture. The Vizio handles the sound.
If your budget allows only one purchase, the Samsung S90H should come first. Great visuals transform your viewing experience. You can upgrade your audio later.
If you already own a decent 4K TV and want better sound, the Vizio M512a H6 is a smart buy. It delivers real surround sound with Dolby Atmos for under $400.
For the best home theater experience, buy both. A 65 inch S90H paired with the Vizio M512a H6 gives you OLED picture quality and 5.1.2 surround sound for around $3,000 total.
