The current TV also outputs audio from an analog audio out (RCA connectors) to a whole house audio system.
I have a couple questions/problems
1.) My room can get pretty bright, should I stay away from OLED? I have a home theater so movie night tends to be in the theater.
2.) I have read HDMI is limited to 30 feet. Is that a hard rule? I can run CAT6 and video extender but I'd prefer not to.
3.) I need to get analog audio out somehow. Not all TV's have straight audio out but they do have Audio Return Channel. Can I convert that to analog? What is the best devise? Does that increase volume with the Volume of the TV?
I have not looked at any TV's but I can fit a 55" and I am looking at the better OLED offerings from LG and LCD from Samsung.
HDMI is not limited to 30'. What is limited is the cable certification, which is 25' (some mfrs have been able to certify out to 30'). Premium High Speed HDMI cables, which come with a QR label for authenticity are the HDMI.org approved cables. However, even with a proper certification there are no 100% guarantees that the cable will work as expected because there are other factors involved besides the data pipe (cable). You can use an active cable, which is designed to extend that 25' length by incorporating chipsets in the sink end (tv side) for error correction, timing, etc. They work great for 1080p but 4k HDR can be more difficult.
You can run CAT-6 and terminate with HDBT (expensive) but you should be using solid core
CAT-6 cabling (non-CCS and not CAT-6 ethernet patch cable).
If your cable run is over about 20', and you want to push 4k HDR, then you might want to look into a hybrid fiber cable instead of a copper-based cable. They are expensive but almost a necessity for long 4k HDR runs becauae 4k HDR can have distance issues.
ARC can be problematic over long distances. It works for some and for others it's a pain-in-the a$$. The reason being is that some systems (quite a few in fact) have ARC associated with CEC, and CEC is very problematic due to non-standardization of the protocols. I don't think you can use the ARC feature to analog the way you want to but maybe somebody else can give you a more definitive answer. ARC is dependent upon the HDMI chipsets in the source and sink device.
You can always use optical out from the tv to the receiver for discrete 5.1 audio from OTA television (antenna) or the SmartApps. ARC currently offers the same audio format as optical but some systems allow you to use ARC for lossless Atmos if that's what you want/need.
You mentioned you have a home theater so what kind of receiver do you have? If it is old, and you get a new new tv you may have to upgrade your receiver to take full advantage of what your tv can do. For a bright room, an LED may be a better choice than an OLED. I have an OLED but I can control the lighting in the room so it's not an issue, day or night.
