a few days ago, my Rift headset broke (one earphone stopped working) and I RMAed it at a local hardware store where I have bought it. The very next day, I've received a refund, so I immediately proceeded to buy a new Rift from them. My first Rift was the original bundle that came with remote, XBOX controller and one sensor, but they are not being sold anymore, so I've gotten the new one, that's bundled with two sensors and a touch controllers.
I did notice some build quality differences, such as that the new foam padding is made from a much cheaper material. I did not mind that, since I bought a VRCover one anyway. What took me by a surprise though, is that my new Rift no longer works with my 2 meter HDMI extension cable. If I plug it directly into my GPU, it works well, however if I plug it via the HDMI extension cable, I get just a black screen (but Oculus software does not report HDMI not connected warning). It is the very same cable my previous Rift worked with, and it is plugged in the very same ports. I don't think that the new units should have any significant hardware difference, which could cause this.
Is there something I can try?
Thanks in advance.
