Yep, what few “features” the screen has have all been turned off, it is just kind of crap, when it got its (singular) software update, the update progress screen was displaying the top half of its frame on both halves of the screen.

But if a codec change or such happens (like to AV1 or h.265), it might not, we have an older 4k smart tv (Sharp Aquos LC-60UE30U) that can’t handle 4k streaming without dropping to single digit fps.

In my experience the USB 2.0 drives are slower to boot initially and install, but I think they decompress to RAM since for me it has never impacted performance while using the Live functionality, so if you are ok waiting for boot/install they are just fine.
