Samsung QN95D Neo QLED 4K TV troubleshooting

Samsung QN95D Neo QLED 4K TV (QN55/65/75/85QN95D*): ports (from AVS Forum and RTINGS coverage); where the ports are; reading the label; anti-glare and sitting; remote and updates; neo QLED's brightness in practice, and a fix for each symptom below.

Ports (from AVS Forum and RTINGS coverage)
Four HDMI 2.1 ports, one of them eARC, plus a LAN port, two USB 2.0 ports, optical audio out, Bluetooth 5.2 and Wi-Fi. Reviewers report all four HDMI ports carry the full 48 Gbps, so any of them takes a 4K 120 Hz console.

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

Panel — Mini-LED LCD
Neo QLED Mini-LED LCD with Quantum Matrix dimming — a backlight, so blooming/halo around bright objects and raised dark-room blacks are normal LCD behavior, not a fault.
One Connect box
The QN95D's defining feature: ALL inputs live on a separate One Connect box that reaches the TV over a single thin cable, not on the panel. A 'no signal', HDMI or ARC problem is diagnosed at the box — check the source and the One Connect cable there first, not the back of the TV, which has no inputs of its own.
No Dolby Vision
A Dolby Vision title falls back to HDR10+; that is by design.
Smart platform / gaming
Four HDMI 2.1 (on the One Connect box) with 4K 144 Hz, VRR (FreeSync Premium Pro) and ALLM. Update at Settings › Support › Software Update; screen share via Smart View and AirPlay 2.
Where the ports are
The ports live on Samsung's One Connect box rather than on the panel, which is why a wall-mounted QN95D can have a single thin cable to the screen.
Reading the label
The QN95D carries its model, QN-something-QN95D, and serial number on a label at the back, near the ports. Samsung's service uses the full code, which includes the screen size. Photograph the label before wall mounting.
Anti-glare and sitting
Samsung gave this Neo QLED an anti-glare screen, which helps in a bright room. Place the set where windows are to the side, and check the picture in daylight before changing settings. A matte finish shows less reflection but can look a little softer in a very bright room.
Remote and updates
The Solar Cell remote charges from light and from a USB-C port. Update the TV from Settings, Support, Software Update every few months, since Samsung fixes bugs and adds features.
Neo QLED's brightness in practice
The QN95D is among Samsung's brightest Mini-LED sets, and its Glare Free coating keeps reflections down in a lit room. The brightness setting and the Eco Solution options can darken the picture if they are left in automatic, so turn them off when judging how bright it is.
The One Connect box
Inputs and the power for the panel come through the One Connect box. Keep it somewhere that air can pass, put the cable in a protected channel and use its own cable only, since a fault in the box or the cable looks like a dead TV when the panel itself is fine.
Updates and Smart Hub
Check Settings, Support, Software Update every few months, and restart the TV after an update. A Smart Hub that has become slow often recovers after clearing an app's cache or deleting apps you do not use.

Questions that only have an answer for the Samsung QN95D Neo QLED 4K TV

My Samsung QN95D shows no signal but the cable is fine.+

On the QN95D every input is on the separate One Connect box, not the TV — the panel has no HDMI ports of its own. Confirm the source is plugged into the One Connect box, and that the single One Connect cable between the box and the TV is fully seated at both ends. A signal fault here is almost always the box or that cable, not the panel.
