What is true of this model and changes how you fix it

• Panel — Mini-LED LCD, not OLED
  Neo QLED is a Mini-LED LCD with Quantum Matrix local dimming. It has a backlight, so a faint halo/bloom around bright objects on a dark background and slightly raised blacks in a dark room are normal LCD behavior, not a fault — the opposite diagnosis from an OLED. Larger QN90D sizes use a wide-angle (ADS) panel and smaller ones a VA panel, so viewing-angle and contrast differ by size.
• No Dolby Vision
  Like every Samsung TV, the QN90D does NOT support Dolby Vision. It plays HDR10, HDR10+ and HLG. A title that offers Dolby Vision will fall back to HDR10/HDR10+ here — that is by design, not a fault, and no setting or update adds Dolby Vision.
• Smart platform
  Tizen with Smart Hub and the Samsung Gaming Hub (cloud gaming). Update path is Settings › Support › Software Update; screen sharing is Smart View (Miracast) and AirPlay 2. webOS, Google TV and Roku steps do not apply.
• Gaming / HDMI
  Four HDMI 2.1 ports with 4K 144 Hz, VRR (FreeSync Premium Pro), ALLM and the Game Bar. Enable Game Mode for the input; the Game Bar shows the live refresh and VRR state, which is the fastest way to confirm whether 120/144 Hz actually engaged.
• Ports (from published spec listings)
  Four HDMI 2.1 ports, two USB 2.0 ports, a LAN port, optical audio out, Wi-Fi 5 and Bluetooth 5.2. All four HDMI ports take 4K at 120 Hz, and 144 Hz from a compatible PC graphics card.
• Refresh rate by size
  Every size except the 98-inch supports 144 Hz with AMD FreeSync Premium Pro.
• Audio
  A 4.2.2-channel system with Dolby Atmos, Object Tracking Sound+, Q-Symphony, Adaptive Voice Pro and Adaptive Sound+.
• Update policy
  Samsung announced seven years of Tizen OS updates for TVs released in 2024 or later, which puts a launch-year QN90D on updates until about 2031.
• Remote
  The QN90D ships with Samsung's SolarCell remote, which charges from light and by USB-C rather than replaceable batteries; a remote that lights its LED for 5 or more seconds after a button press needs a charge, and a full charge lasts up to two years of normal use.
• Also covered
  Q80C QLED TV, ports and panel (from Tom's Guide's review): Four HDMI 2.1 ports on a 120 Hz panel, with HDR10, HDR10+ and HLG and 40 W audio. The set includes a Game Hub.

• Also covered

• Also covered
  S95D OLED TV, wall mounting: Any 400 x 300 VESA mount fits, but for the TV to sit fully flush Tom's Guide says you need Samsung's Full-Motion Slim Wall Mount, which it priced at $159.
• Also covered
  S95D OLED TV, setup: Tom's Guide needed help lifting the screen and spent about 15 minutes getting the stand to fit because some screw holes did not line up with the heavy base. It also warns the glass front could crack if you press too hard on it.
• Also covered
  S95D OLED TV, screen: A QD-OLED with a glare-free finish that the review is built around.
