While not ideal, you could utilize an HDMI 2.1 switch
I asked Grok for clarification on earc HDMI 2.0 vs earc HDMI 2.1:
The audio capabilities of HDMI 2.0 eARC and HDMI 2.1 eARC are largely similar, but there are some differences due to the enhanced features of HDMI 2.1. Here's a breakdown:
Similarities:
• eARC (Enhanced Audio Return Channel): Both HDMI 2.0 and HDMI 2.1 support eARC, which is an improvement over the standard ARC (Audio Return Channel). eARC allows for high-quality, uncompressed audio formats like:
• Dolby Atmos (via Dolby TrueHD)
• DTS:X (via DTS-HD Master Audio)
• PCM up to 7.1 channels
• High-bitrate audio up to 192kHz, 24-bit.
• Bandwidth for Audio: eARC in both versions provides up to 37 Mbps of audio bandwidth, which is sufficient for lossless audio formats.
• Lip-Sync Correction: Both support automatic lip-sync correction for synchronized audio and video.
• Compatibility: eARC on both HDMI 2.0 and 2.1 is backward compatible with ARC, ensuring connectivity with older devices.
Differences:
• HDMI 2.1's Enhanced Capabilities: While the core eARC specification is the same, HDMI 2.1 has a higher total bandwidth (up to 48 Gbps compared to HDMI 2.0's 18 Gbps). This doesn't directly affect eARC's audio performance, but it allows HDMI 2.1 to handle more demanding video formats (e.g., 8K, 120Hz) alongside high-quality audio, reducing potential bottlenecks in complex setups.
• Future-Proofing: HDMI 2.1's eARC implementation may benefit from firmware updates or device-specific optimizations that leverage the higher bandwidth or newer processing capabilities, potentially improving stability or compatibility in advanced AV setups.
• Device Support: Some HDMI 2.1 devices may include additional audio features or better integration with modern AV receivers, though this depends on the manufacturer's implementation rather than the eARC standard itself.
Conclusion:
For most practical purposes, the audio capabilities of eARC in HDMI 2.0 and HDMI 2.1 are functionally identical for transmitting high-quality, uncompressed audio formats. The differences lie in HDMI 2.1's overall bandwidth and potential for better system performance in complex setups. If you're focused solely on audio (e.g., connecting a soundbar or AV receiver), HDMI 2.0 eARC is typically sufficient. However, for future-proofing or if you're using high-resolution video alongside audio, HDMI 2.1 may offer indirect benefits.
If you have a specific setup or device in mind, I can analyze further or check for compatibility details if you provide more information!
So essentially eARC is eARC. There's no difference in audio bandwidth between HDMi 2.0 eARC and HDMi 2.1 eARC. The only difference as far as I can tell is the higher bandwidth for 4K 120.
This Qm7k 98 inch is a great deal, but after I invested in top of the line samsung 990D sound bar, not sure if I should get this TCL qm7k? even if I go up to Qm8k still the same scenario.
even the basic lower end samsung 98 inch DU9000 has earc 2.1 so I don't understand why TCL doesnt offer that in their TVs. I reached out to TCL support and they told me not just QM7k, but also QM8k doesnt offer 2.1 earc either. They told me that at this time TCL doesnt have any TV that offers earc 2.1, due to limitations of the chip they use. Now who knows if this information totaly accurate but I can confirm that TCL line up doesnt offer a single TV with earc 2.1 so it makes sense.
here is what I got from AVS website:
If your TV's eARC (Enhanced Audio Return Channel) is on an HDMI 2.0 port, it means that while the TV supports eARC, it might not be able to utilize its full potential. While eARC is technically part of the HDMI 2.1 standard, it can be implemented on some HDMI 2.0 devices. However, HDMI 2.0 has bandwidth limitations compared to HDMI 2.1, which can restrict the types of audio formats that can be transmitted with eARC, especially for uncompressed audio formats like Dolby Atmos and DTS:X, it's recommended to have a TV and sound system that both support eARC on HDMI 2.1 ports.

I highly recommend asking Grok for advice just like you were talking to a salesperson. I think you'll be amazed how accurate and detailed the response are, including all the pros and cons of any model television you are considering, and all the components you are using in your setup. I just spent 30 minutes with Grok talking about all my AV gear and concerns about compatabilities and comparing the TCL 98 QM7K with the Hisense 100 U7Q, and for my setup, Grok confirmed the TCL to be the better choice. Grok may tell you otherwise, give it a shot and let us know how it goes

I had originally ordered that one, before changing my mind… twice… and deciding on a tilt mount. Decided I will likely be reclined a lot of the time watching, therefore a little tilt might be ok.

After some consideration, a minor degree of tilt will also help with any glare from room lighting. Originally I wanted a flush mount to get it as close as I could to the wall, but as others have mentioned, changing out cables gets difficult without any gap to work in. Hopefully I never have to change cables… but if I do I don't want to get all frustrated
The other option is to use the "flush mount" but with the included bolt spacers on the top holes on the TV to add permanent tilt. Hope that makes sense.

Just as spacers can be used on the top of the tv to tilt down, they can be used on the bottom to correct the angle upward a bit if it sags.
I need 7-8 degrees of tilt, and want some flexibility. The bracket I'm using maxes at 10 degrees of tilt, worst case scenario I add the spacers to the bottom or use some shims to correct 2-3 degrees

I only see 4% cash back, might be user specific
