Honestly I would worry less about HDMI 1.4 and start looking forward to HDMI 2.0. If you did buy a HDMI 1.4 tv I don't think you would have any problems with your reciever unless it is 4K or you are using 3D. If someone has information counter to this please jump in.
If you do plan to buy a new reciever at some point, I would wait until HDMI 2.0 is in stores later in 2014. The good news is that 2.0 is completely BC with 1.4 and even uses the same cable. Just a recommendation.
I'm in the same boat, with a older reciver.
