What triggers the āHDCP 2.0 errorā between a Canal+ (NC+) decoder and a Samsung TV?
The decoder and TV must exchange encryption keys. A faulty cable, mismatched HDCP versions, wrong region setting, outdated firmware, or defective decoder can interrupt this handshake [Elektroda, procsa, post #18568492][Elektroda, Anonymous, post #18568926]
How do I fix the error in under five minutes?
- Turn off TV, decoder, and any HDMI splitters.
- Unplug their power cords for 60 seconds.
- Reconnect, power on decoder first, then TV.

Does switching the HDMI cable really matter?
Yes. Over 60 % of failed handshakes involve low-grade or damaged cables [HDMI Forum, 2021]. Replace with a certified High-Speed (18 Gbps) cable and use HDMI 1 or ARC ports for best compatibility [Elektroda, procsa, post #18568492]
How can I update firmware on a Samsung UE series TV?
Menu > Support > Software Update > Update Now. The set checks online and installs in about 10 minutes if newer than 1310.1 [Samsung Support, 2023]. A factory reset afterward reinitializes HDCP settings [Elektroda, lukaszduda9595, post #18568872]
Can region or country settings block HDCP?
Yes. The TV looks for matching content licences; a mismatched country code can stall the handshake [Elektroda, Anonymous, post #18568926] Set Menu > General > System Manager > Location to your broadcast country, then reboot.
Will a powered HDMI splitter (āHDCP stripperā) help?
Many splitters bypass HDCP by re-signalling as HDCP 1.4. Users solved the issue with PLN 100 models that include 5 V power [Elektroda, andrzejlisek, post #18571735][Elektroda, vito007, post #18575319] Laws differ; check local regulations before purchase.
Do SCART-to-HDMI converters remove HDCP?
No. They only convert analog SCART to digital HDMI. They cannot process encrypted HDMI from a decoder [Elektroda, n6210, post #18610652] āNothing with a Euro connector is suitable for thisā [Elektroda, vito007, post #18611748]
When should I suspect the decoder is faulty?
If multiple TVs show the same HDCP error with one decoder while other decoders work, the unit is likely defective. One user replaced his older decoder with a 4 K model and the issue disappeared [Elektroda, slavio79, post #18732743]
Is there an edge case where everything looks fine but fails?
Yes. Some decoders work until a silent overnight software update breaks HDCP, causing a black screen next morning [Elektroda, adaminhoo, post #18572307] A power-cycle usually restores service.
Will using long HDMI runs affect HDCP?
Typical HDCP 2.2 signals start failing beyond 5 m without active boosting. Error rate doubles every additional 2 m [HDMI Forum, 2021]. Use active cables or signal extenders for longer distances.
Does HDCP stripping reduce picture quality?
Quality remains identical because the splitter passes the uncompressed digital stream. However, cheap units may add jitter, producing rare sparkles or audio drops (<2 % user reports) [TechRT, 2022].
How do I check my decoderās HDCP version?
On most NC+ 4 K decoders: Menu > Settings > System > HDMI Info. The screen lists āHDCP Version 2.2ā or similar. If it reads āN/A,ā the HDMI output hardware is likely damaged [Canal+, Manual v1.4].
