Map the source to the television port
Identify the external player or console and follow its connection to the TV, noting any receiver or soundbar in between. Record the television’s input label and physical HDMI port. A renamed label such as Movies can be useful to the household while obscuring the actual numbered connection in a support note.
If the programme is running in a built-in television app, say so. That app is not an external HDMI source simply because the same remote also controls a connected box. Start with the path actually delivering the picture under discussion.
Use the Canadian guide’s stated model-year branch
For its 2022-and-newer example, Samsung Canada directs Settings, All Settings, Connection, External Device Manager, Input Signal Plus. Enable it for the HDMI port connected to the HDR-capable device. Use the real model’s manual if its settings layout differs.
Record the existing port setting before a deliberate change. Do not switch every input while also altering the source output format; one controlled change makes the outcome easier to interpret. If the wrong port was selected, no observed improvement on the intended source would establish the setting’s effect.
Keep signal capability separate from programme identity
The port setting does not identify the original movie’s codec or establish that a specific title is HDR. Keep source output information, the TV’s received-signal indication and the programme’s documented format separately. A capable HDMI path and an SDR programme can be valid together.
Samsung’s guide also discusses HDR+ processing on older televisions and HDR10+ format terminology. Those descriptions should not be collapsed into one universal switch or treated as evidence that processing creates the original HDR master. This article uses only the scoped external-input procedure.
Preserve a clear result and return path
After the intended check, note whether the source remains visible, which output format it reports and what the television indicates. If the picture disappears, return to the documented configuration that worked and consult the exact equipment manuals instead of assuming more processing must be enabled.
No Samsung television or HDMI source was tested here. The guide follows the Canadian support route and avoids promising an unsupported codec, extra source detail or identical settings on every older Samsung model.
Sources and scope
Scope notes distinguish published documentation, supplied information and editorial methods. They do not report a hands-on service test.
- Samsung Canada: external HDR input settings — Official September 2026 body explicitly applies to Canadian TVs,2022-and-later Connection route and per-HDMI-port enablement; older processing claims not adopted as universal instructions.
