What to know before buying

Listing details to confirm

The listing is inconsistent on length: the title says 6.6 ft, while the technical details give 50 Centimetres. Its headline and feature text claim 16K@60Hz, but other listing details give no independent confirmation of achievable modes. Verify the selected cable length and that your source and display support the desired resolution and refresh rate. Customer feedback also reports mixed results at 4K 240Hz and occasional display blackouts.

Customer feedback praises perceived build quality and value, while reports about functionality and bandwidth are mixed. Some say it works at 4K 240Hz, while others say advertised speeds are not achieved. Feedback on screen reliability is also mixed, including reports of no flicker and an account of random blackouts. These concerns matter if you need stable high-refresh output, and the listing's claimed modes should not be treated as verified performance.

Mixed feedback

Reports about functionality and bandwidth differ, including conflicting experiences at 4K 240Hz.
Screen reliability feedback is mixed, with reports of flicker-free use as well as random blackouts.
