Even if you would have 1.4 cables, your receiver only sends 1.3 then.
Probably your Sony receiver is going to get an update. BTW which model?
Hi,
the receiver is Sony STR-DA5300ES. Is it possible to upgrade the HDMI ports just with firmware upgrade?
Thanks
There is no universal answer: HDMI receiving part must be constructed with FPGA instead of ASIC chip, FPGA must be connected to enough memory that is fast enough, firmware must include not only main ROM update but also other programmable chips... lots of factors. Only a Sony engineer would know for sure.
