Which AV receiver do you have? Unless it predates HDMI you connect all devices to the AVR which in turns connects to the TV, with all cables being HDMI. If your AVR is old the best thing is to upgrade it as this will be the only way to get compliance with HDCP 2.2, high quality audio, HDR and other features.
Your Yamaha must have been released 15 years ago and is not able to provide the features you want.
You might get a Black Friday deal, there's quite a number available now.
As for your new AVR: look for wide support of standards and future-proofing as much as possible. My Marantz NR1711 has six HDMI inputs which support all HDR formats (Dolby Vision, HLG, HDR10 and HDR10+), 4:4:4 Pure Color sub-sampling, 21:9 video, BT.2020 pass-through and current HDCP 2.3 copy-protection standard. There's also a dedicated 8K HDMI input. It's slimline as well.
