Upgrading Projector - Current Cables Work?

I tried the search, but found somewhat inconclusive responses. My 7 year old projector is likely needing to be replaced. As you'd imagine, the cables purchased in 2012 are buried in the wall (25ft cables). Fortunately, they are still available from the same vendor most here will know. Specs:

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
3D video
Audio Return Channel
Deep Color up to 16-bits per channel
x.v.Color™
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?

I thought copper was copper. But I can tell you that we are very close to exceeding the capabilities of what copper can do, I don't think it can go beyond [email protected]
It will be fiber optic only by that point. Which will likely occur within 10 years, if not less...

You'd be better off removing the drywall and installing 1/4" flex conduit, with the anticipation of needing to pull a new wire through it in the not-too-distant future.

In data centers like Google, Youtube, Microsoft, Facebook etc they are all using optical networking to achieve 100gbps per port (for several years now). Copper just can't do it (not at the lengths typically-required anyway...)

I understand where you're coming from as I spend a fair bit of time in data centers like those you listed. I'm hoping to avoid taking the projector screen down, tearing into drywall, etc. If the answer is I need to do it or am going to be stuck with current image quality as the max with those cables, I'll consider it.

My ideal state is getting the newest cable box, replace dying projector, then ride this setup for 7 years as I did with current setup. Between now and then we're probably moving to new house anyway when can hit reset button / get conduit from the beginning.

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.

I never trust an atom, they make up everything.

If you upgrade the Projector you will usually be able to send the same range of signals as you currently send over the installed cable - if the projector (and one or more of your Source devices) is capable of higher bandwidth signal formats that is where your problems will likely start.

To make use of the new projectors full capabilities you will likely want to consider replacing the HDMI cable and ensuring your AVP/AVR will support those higher bandwidth signals too.

The PS4 will 'work' in your current and revised setup - it just may be limited in what format you set its Output too.
