Choosing a long HDMI cable that supports 1080p60

Question

Iron

Good day.

The other day there was a horror called "overhaul", among other things, it was decided to remove the wires for the home theater into the walls.
You need a 15-20m cable to run FullHD through it to the projector, but the problem is that there is no room for error - the cable is walled up, and the projector has not yet been purchased.

Options:
1. Products from half-names - Telecom, VCom, AOpen and others like them
unfortunately, no one indicates the thickness of the conductors, and at such a length you need at least 24AWG
2. Item 1 plus an amplifier aka a signal repeater
3. Throw two Cat6 / Cat7 coils and run on them - through Chinese adapters, or solder

Please share a similar experience

Answer 1

In my opinion, there is only one way out. Take a monitor/TV set from any friend/neighbor and check it out. It's easier than redoing the wall later.

Answer 2

Can a cable channel be walled up instead of a cable? Thus, leaving yourself the right to make mistakes.

Answer 3

On ebay there are offers to sell 20 m of cables, for example .

Answer 4

1080p60 at 20 meters in its pure form will not work. Only recently tested on good 15m cables. Only 720p was pulled out.
ATEN makes inexpensive amplifiers and converters. BUT! Price and sophistication is not an indicator.
You have to test anyway.
Here VE800 inspires confidence.
