Review on Gofanco Prophecy HDBaseT Extender CAT7 230Ft by Nicole Cook

For the past few months I've been using it for my office PC with a 3840x1600@60Hz display and USB keyboard/mouse and gamepad. This uses a standard CAT6 75 foot patch cord. A few things to note: while it supports an input resolution of 4K@60Hz with 4:4:4 color, the output is somewhere between 4:4:4 and 4:2:2. To my knowledge this is a limitation of HDbaseT 2.0 and the current Valens chipsets and I don't think a competing HDbaseT solution can offer anything better. However, lowering the resolution and/or refresh rate can result in true 4:4:4 color output, e.g. B. if you need to do color-sensitive work temporarily. many USB 2.0 devices on the receiver side. I've tried some of the best host powered USB 2.0 hubs and couldn't get around this limitation. A simple fix would be to use a different CAT to USB cable. However, for my purposes USB provided via HDbaseT worked fine with this device. Edit: I've concluded that this device always does color space conversion (CSC) to "support" 4K@60Hz 4:4:4. Essentially, this means that the resulting image will have a picture quality of 4:2:0 even if the source is 4:4:4. Now this is due to the bandwidth limitations of HDbaseT itself, however other products can perform 'visually lossless' compression via DSC/AVLC, which is likely to result in better picture quality for 4K@60Hz 4:4:4 sources. So in my opinion it is a bit misleading to say that this device supports 4K@60Hz 4:4:4 as the resulting image quality is exactly 4:2:0.
