1. Please make sure that your HDMI cable is connected to the HDMI Output and not on HDMI Input.
2. The HDMI connection cable is defective or does not provide sufficient speed for boosted video streams of the Zappiti 4K HDR. In this case, try replacing the HDMI cable or try the HDMI cable supplied in the accessory bow with the Zappiti media player. If the length of your cable exceeds 3m, you will need a high quality cable high-speed compliant with 18 Gbps or more.
Note: some very expensive high-quality cables are not compatible with the Zappiti 4K HDR uncompressed video output.
This issue can happen especially on long lengths. To ensure this, try the following operation: connect your Zappiti directly to your TV or projector via the HDMI cable supplied with the player. If it works, it means replacing your HDMI cable with a higher quality one. Beyond 8 m (314") , we recommend the use of AOC fiber optic cables from Suprawhich you will find here:
Please be aware that so many HDMI optical fiber are not working fine. On 10 optical HDMI cables we tested with Zappiti, only 2 brands was working fine. Supra AOC is working very well with Zappiti (tested). This is why we highly advise it beyond 8 m (314").
3. Maybe your AV receiver does not support the boosted video signal of the Zappiti 4K HDR (Zappiti MagicPixel v2) or with HDMI 2.0. To test this, please try connecting your Zappiti player directly to your TV by bypassing your AV receiver.
4. The TV does not support the resolution sent by the Zappiti 4K HDR. In this case, restart the media player and change the video settings.
5. Your TV, monitor or projector is not equipped with HDMI port and you use an HDMI> DVI or your display is not HDCP 1.1 compliant. Unfortunately, the Zappiti 4K HDR requires a TV, monitor or projector supporting HDCP 1.1 minimum to operate digital video link. To overcome this problem, you can try to connect a switch or HDMI splitter. Indeed, in order to operate, many video splitters or swichs inhibit HDCP and can sometimes let in some cases the video signal. But this is not 100% reliable solution. The other solution is to use the analog video output.
6. Maybe your TV does not support the boosted video signal of Zappiti MagicPixel.
The Zappiti 4K HDR requierements for 1080p output are:
- 1080p compatibility.
- Y'CbCr 4:4:4 compatibility.
- 12-Bit / primary color compatibility (Deep Colour / Deep Color).
- xvYCC (or x.v.Colour / x.v.Color).
To be sure if your TV is or is not compatible, please try to connect your Zappiti 4K HDR to another TV. If your TV is not compatible with 1080p / xvYCC / Y'CbCr 4:4:4 / 12-Bit, please try to change the video settings in Y'CbCr 4:2:2 / 8-Bit.
If your TV or front projector is compatible with 4K but not compatible with HDMI 2.0, you can use an HD Fury box:
7. You also should to switch on your devices in the following sequence:
1. AV receiver (if you have one).
2. Zappiti player.
