Just a quick note on cheap HDMI cables. I’ve previously ranted about the unfortunate fact of expensive HDMI cables being sold in consumer shops, the outlandish claims so often made for them.
A while back I purchased from The Cable Connection a bunch of cables, including a ten metre HDMI one plus a 5 metre one plus some shorter ones. The cost of the ten metre one? Just $49.95 (one of my other ten metre cables retails for about $700!).
As it happens I for the moment have a full 4K system — UHD TV, Oppo Blu-ray player with 4K upscaling and home theatre receiver with 4K passthrough and upscaling. Which makes for an opportunity to test out the cables. 4K worked fine via 2 metre from Oppo to the receiver and thence via 5 metre cable to the Sony 4K TV. The signal was 24p.
All cables were low cost ones from TCC. I switched to a ten metre TCC cable from receiver to TV. Still perfect performance. The Oppo wouldn’t upscale 1080i60 to 4K at 30p, which is the highest bandwidth signal the TV is capable of accepting. But the receiver could, so I put on a 1080i60 Blu-ray disc and had the receiver upscale it. Still perfect performance at 4K and 30p.
Don’t get ripped off on your HDMI cables.
