This High Speed HDMI Cable supports the following general features:
Silver plated conductors for superior signal conductivity
10.2Gbps data throughput
CL2 in-wall fire safety rating
22AWG silver plated copper conductors
Gold plated connectors
It supports the following HDMI features:
1080p resolution at 60Hz
4K resolution at 24Hz
Audio Return Channel
Deep Color up to 16-bits per channel
High Definition Audio, including SA-CD, DVD-Audio, DTS-HD Master Audio™, and Dolby TrueHD™
I use it primarily to watch live sports via Cable provider. It would be nice to allow my kids PS4 to run on it, but not if it means opening up the walls to replace cables. I will occasionally mirror my laptop via wifi connection to the projector (thru receiver), but not worried about 4K resolution on that. I'm hoping to get 7-10 years out of whatever swap out here.
I also have all video sources running thru Integra 40.4 which might impact the image and need to be replaced? It says "4K upscaling", but I haven't gotten to research that yet.
Do you experts see any red flags with the cable specs listed above, or is it really going to be try it and cross my fingers?
Premium High Speed HDMI cables is about the best you can do at present for 4k HDR. They are tested and certified by HDMI.org to meet all HDMI 2.0 hardware specifications. Your other option would be a hybrid fiber cable (Ruipro4k). However, 25' is the maximum certifiable distance for a passive cable (Premium), and if your cables are in-wall, you'll need to replace them. As mentioned above, the use of a 1.5" to 2.0" conduit is highly recommended. Using a conduit is the ONLY way to future proof your cabling because as video standards change, the cabling requirements, which always lag behind, will change as well.
The cable you list is probably fine for HDMI 1.4 specifications (10.2Gbps) but the current HDMI 2.0 specifications are 18Gbps so you really should upgrade your cabling if you plan on getting new equipment or want to keep up. The newest HDMI specification have recently been released, which is HDMI 2.1 (48Gbps) but there aren't any consumer devices yet (or only a couple) that are fully HDMI 2.1 compliant, let alone source material so you do have a lot of time left if that is a future plan of yours. However, cabling will be an issue, hence the use of a conduit. Distance is the achilles heel of HDMI cables so the further apart your devices are from your panel, the more likely you are to encounter issues. And, to confound the issue, 4k HDR does not do well with adapters, extenders, wall plates, etc. Bend radius and strain on the HDMI input (too tight of a connection) are also contributing factors to a successful cable run. The most reliable connection is a single cable, source to sink.
My feeling is that if you replace your projector with an HDMI 2.0 capable projector, you will encounter issues with the existing in-wall cable.
