Questions about Digitec HDMI-HDMI 2.1

This is not currently planned. However, I will be happy to pass on your request to the relevant department. :)

Sorry, I am out of my depth

According to the specification, the HDMI 2.1 cable from Digitec supports a bandwidth of up to 48 Gbps, which is theoretically sufficient for 4K at 240 Hz. However, the available information specifically mentions 1440p at 360 Hz as an example, not explicitly 4K at 240 Hz. The HDMI 2.1 standard itself allows 4K at 240 Hz, but the actual support also depends on the cable quality and the connected devices.

The HDMI 2.1 cable theoretically supports 1440p@360Hz as the HDMI 2.1 specification provides enough bandwidth with up to 48Gbps. However, the actual performance depends on the connected device - some monitors like the Alienware AW2725DF limit HDMI 2.1 to 144Hz at 1440p, while others like the MSI MPG 271QRX support 360Hz. For exact details on compatibility, you should check the manufacturer's specifications for your monitor. The cable itself fulfils the technical requirements.

The cable does not directly support 1440p at 360 Hz as it is designed for 120 Hz at 4K and 60 Hz at 8K. There is no specific information on whether it supports 1440p at 360 Hz as this specific combination is not mentioned in the specifications. You should check the technical details of your device to make sure it is compatible with this cable.

I'm not sure, but my Philips 65OLED808 displays the same message no matter which Ultra HDMI cable I use. I have tested different ones. I think it just always shows the message regardless of whether the cable is already correct or not.

Under the following link you will find an alternative from a marketplace retailer: Primewire HDMI cable 2.1, 8K @ 120Hz / 4K @ 240Hz DSC, Ultra High Speed, Nylon sheathing, HDR, ARC (2 m, HDMI)

That's all right. No difference. If pc no difference. With console anyway. Because Xbox Series s/x and PS5 only run up to 120hz.

According to our information, this cable offers a transmission rate of 48Gbps.

So far we do not offer this under our own brand, but we will be happy to pass on your input.

It works for me with Netflix on the Apple TV and I think that also does HDCP.

For 1440p with 144Hz, an HDMI 2.0 is also sufficient, so you can take the somewhat cheaper variant.

They arrived in a plastic bag. So I don't think there was a sticker on them 😅

The latest standard is HDMI 2.1, which is perfectly suited to a PS5.

For HDMI cables, the version is relevant. HDMI 2.1 is the latest standard, which copes with the common picture resolution formats without any problems. However, 5120*1440 is not one of them. Many users complain about problems with this format with HDMI. However, there are users who get a decent picture with USB-C in this format. As a Mac user myself, I have found that USB-C delivers a better picture at high resolutions than HDMI. Personally, I would only use USB-C. However, due to the work equipment, I have no choice but to connect the business notebook to the monitor via HDMI. There are simply not enough monitors on the market that have a double USB-C connection.

According to the general information on HDMI, an HDMI High Speed cable complies with the HDMI 1.3 / 1.4 standard. In order to have an HDMI 2.1 cable, it would have to bear the designation HDMI Ultra High Speed or a corresponding label. https://www.heise.de/tipps-tricks/HDMI-Kabel-Welche-Unterschiede-gibt-es-5074567.html

According to the item description, it should support 120 Hz for 4K, and 60 Hz for 8K.
