Sorry to hear that your cable stopped working. If you have purchased it at our online store, you have the possibility to open a warranty case in your customer account.

Yes, DP 1.4 can handle 240hz at 1080p.

The DisplayPort cable does not explicitly specify a frame rate of 144 Hz. However, DisplayPort cables can generally support higher frequencies if the connected hardware allows it. For a frequency of 144 Hz, make sure that the monitor and graphics card support this frequency via DisplayPort.

According to our information, this is a connecting cable.

Maximum 240Hz, but I think that's what you mean.

Yes, this one is suitable. DisplayPort 1.4 technology and DisplayPort compliance certification ensure compatibility with all DisplayPort-enabled devices.

No. Hasn't happened yet.

The DP 1.4 standard offers the possibility to compress the data stream (DSC). This is an optional feature and must be supported by the graphics card and monitor. This means that DP 1.4 can also transmit 8K@60Hz. DP 2.0 can transmit 8K@60Hz uncompressed.

Extension cables are always a thing. I would recommend that you just try it out.

Hello 160 hz is the max. frequency. The whole thing is an interaction between graphics card, cable and monitor. Greetings

Hello Enzino, The Displayport cable supports DP 1.2 and DP 1.4 and should work with 144Hz displays. However, it does not make a display 144Hz capable if it is not capable from the ground up. Lindy Switzerland AG

If I understand you correctly, your monitor has 144Hz and you have a graphics card with DisplayPort. The monitor should have a cable that transmits the 144Hz. I returned my cable because this happened to me. But of course you can buy another cable. The price/performance ratio is right for this product.

2560x1440 @ 240Hz should be technically possible as this is a DP 1.4 cable. Throughput is described by the manufacturer as 32.4 Gbit/s and your desired specification needs 24.62 Gbit/s.

The description says 4k@160Hz, so 1080p@144Hz shouldn't really be a problem.

From the beginning of the red ding to the beginning of the green plug is 40 mm.
