gut mit so billigen hdmi kabeln kann man glück haben.aber es kommt halt sehr drauf an was du übertragen willst.
je höher die benötigte bandbreite ist desto unwarscheinlicher ist es das ein signal ankommt. nicht selten liest man das zum beispiel 1080p@50 hz funktioniert, 1080p@60hz dann aber einbricht oder gar 3d. das steht dann auch nur selten bei den billig kabeln bei was sie wirklich schaffen-meist aus guten grund. um sicher zu gehen müsste auf dem kabel ein "hdmi high speed" logo drauf sein - wenn das logo nicht gefälscht ist müsste es dann alles übertragen können:-)
von der hdmi seite mal n paar entsprechende punkte aus der faq:
Q. Does HDMI accommodate long cable lengths?
Yes. HDMI technology has been designed to use standard copper cable construction at long lengths. In order to allow cable manufacturers to improve their products through the use of new technologies, HDMI specifies the required performance of a cable but does not specify a maximum cable length. We have seen cables pass "Standard Cable" HDMI compliance testing at lengths of up to a maximum of 10 meters without the use of a repeater. It is not only the cable that factors into how long a cable can successfully carry an HDMI signal, the receiver chip inside the TV or projector also plays a major factor. Receiver chips that include a feature called "cable equalization" are able to compensate for weaker signals thereby extending the potential length of any cable that is used with that device.
With any long run of an HDMI cable, quality manufactured cables can play a significant role in successfully running HDMI over such longer distances.
Q. How do I run HDMI cables longer than 10 meters?
There are many HDMI Adopters working on HDMI solutions that extend a cable’s effective distance from the typical 10 meter range to much longer lengths. These companies manufacture a variety of solutions that include active cables (active electronics built into cables that boost and extend the cable’s signal), repeaters, amplifiers as well as CAT5/6 and fiber solutions.
Q. How can I tell if a cable is an HDMI certified cable?
All HDMI products are required to be certified by the manufacturer as part of the HDMI Compliance Test Specification. However, there may be instances where cables bearing the HDMI logo are available but have not been properly tested. HDMI Licensing, LLC actively investigates these instances to ensure that the HDMI trademark is properly used in the market. We recommend that consumers buy their cables from a reputable source and a company that is trusted.
Q. What is the difference between a “Standard” HDMI cable and a “High-Speed” HDMI cable?
Recently, HDMI Licensing, LLC announced that cables would be tested as Standard or High-Speed cables.
Standard (or “category 1”) HDMI cables have been tested to perform at speeds of 75Mhz or up to 2.25Gbps, which is the equivalent of a 720p/1080i signal.
High Speed (or “category 2”) HDMI cables have been tested to perform at speeds of 340Mhz or up to 10.2Gbps, which is the highest bandwidth currently available over an HDMI cable and can successfully handle 1080p signals including those at increased color depths and/or increased refresh rates from the Source. High-Speed cables are also able to accommodate higher resolution displays, such as WQXGA cinema monitors (resolution of 2560 x 1600).
wenn dir jemand ein 20m billig kabel andrehen will welches genauso dünn ist wie ein billig 2m kabel wäre ich skeptisch, meiner meinung nach braucht es dann schon ein bisschen dickeren querschnitt der adern und bessere schirmung als ein 2 m kabel um über diese distanz die gleiche bandbreite rausholen zu können.
