Hello guys, I recently acquired a 4k LG OLED Tv, and i'm now wondering how to perfectly connect my sources to keep best audio and video signal. So basically I currently have : - 1 PS4 (hdmi 1.4) - 1 Tv Box (with HDMI 2.0 4k/60 capabilities) - 1 Wii U (hdmi 1.4) - 1 PC (laptop, currently with hdmi 1.4 but might be replaced with a hdmi 2.0 capable laptop soon) - 1 A/V Amp Onkyo TXNR636 (several hdmi 1.4 inputs, 1 hdmi 2.0 hdcp 2.2 input, 2 hdmi output but only 1 with hdmi2.0 hdcp 2.2 support, and limited to 4:2:0 10 bits or 4:4:4 8 bits) with 5.1 sound setup. - 1 Tv (LG OLED 65EF950v, connected to Amp with 1 hdmi, ARC enabled to redirect sound from smart tv apps like netflix, but limited to AC3; It has 3 hdmi inputs) Currently, each source is connected to my Amp, and then the Amp decodes sound and redirect video to the TV with the main HDMI output (hdmi2.0). This setup has limitations : currently I only have 1 4k/60hz capable source, but this will change in a near future : I plan to replace my laptop with a new one having hdmi2.0 output, and there might be an updated "PS4K" I'm interested in, also having this to read UHD BD with HDR and 4:4:4 10bits colors. The key here is that my Amp in-between my sources and my Tv is the weak point : I've read several things about this amp degrading the video signal, at least having impact on the colors. Thus I would like to find a way to connect all my sources to my TV directly but the sources should also be connected to the Amp directly to get the sound, and keep DTS-HD or Dolby THD whenever it is available. But I dont know what do I need to achieve this. Could someone advise me on this ?
