You need a cable certified for the signal mode and length you intend to use, not a premium price tag. A reliable digital connection does not gradually add cinematic detail as the cable becomes more expensive. Unsupported bandwidth or a faulty cable can instead cause dropouts or missing modes.
Specify the actual signal
Resolution, refresh rate, bit depth and colour format combine to determine the connection’s demands. Ordinary streaming video may not require the same mode as high-refresh gaming. Use the official cable certification categories and your equipment documentation rather than choosing solely from a seller’s version-number description.
Test the simplest route
If the screen loses signal, use a known suitable short cable directly between the player and television. Temporarily remove optional adapters or switches where practical. If that works, add the other parts back one at a time. Preserve the original arrangement so you can identify the failing link without creating new configuration problems.
Do not diagnose compression with cables
Blocks around moving players or a soft source picture can be encoded into the stream. Replacing a working HDMI cable will not reconstruct discarded detail. Cable-related symptoms are more plausibly connection instability, sparkles, unsupported modes or a lost signal, though the exact fault still needs a controlled test.
