Questions about Digitec DisplayPort – DisplayPort 1.4

The DisplayPort 1.4 cable supports 1440p with up to 240 Hz, as DisplayPort 1.4 and 1.3 provide the necessary bandwidth for such resolutions and refresh rates.

Yes, the digitec "DisplayPort - DisplayPort 1.4 (1m, DisplayPort)" cable supports 1080p displays at 240Hz. The DisplayPort 1.4 standard offers sufficient bandwidth to handle 1080p resolutions at a refresh rate of 240Hz.

Yes, the cable should support 4K at 144Hz, provided it meets the specifications of the DisplayPort 1.4 standard. DisplayPort 1.4 cables are usually capable of transmitting resolutions such as 4K at 144Hz, thanks to their bandwidth of up to 32.4 Gbps.

The "DisplayPort - DisplayPort 1.4 (2 m, DisplayPort)" cable from digitec is not compatible with monitors that offer a resolution of 1920 x 1080 pixels at 240 Hz without using compression. - DisplayPort 1.4 supports a bandwidth of 32 Gbps, which is not sufficient to transmit an uncompressed signal of 1920 x 1080 pixels at 240 Hz. For this resolution and refresh rate, Display Stream Compression (DSC) would be required to reduce the bandwidth and enable transmission. - Without DSC, the maximum refresh rate at this resolution and bandwidth would be limited to 120 Hz.

No, unfortunately not. It does not say on the packaging that it is compatible. Greetings 👋

I have the same setup with the cable. Yes, it works.

This depends entirely on your laptop and its connections. You will probably need two DisplayPort adapters and two DisplayPort cables. Unfortunately, the Dell S2421HS does not support daisychain, so the monitors must be connected to your laptop individually.
