Looks like it's a no go - the new one makes the same noise. As others have said, I personally can tune it out, as it's pretty quiet and so high pitched that it's almost imperceptible to me. But different people have different sensitivities, and my wife cannot bear to be in the room with it. I thought maybe it was a placebo, but she can seriously be in the next room and tell just by the whining noise, with perfect accuracy, when I turn it on or off.
I love this pj otherwise, but it looks like I just can't keep it; a family room my wife can't bear to be in isn't OK
SO frustrating, because 1080p 120hz with sub-10ms lag is a damn dream come true for me
One quick note on the AVRs -- Obvious thing to look for is HDMI 2.0 & hdcp 2.2 compatibility, and be sure it supports 4k & HDR of course. Beyond that, the 1080p 120hz mode will likely be a problem, but not an insurmountable one if you tinker a bit. My own AVR is a Sony STR-DH590. Out of the box behavior - when I plug the PC into the PJ directly, 120hz is listed as available, but when I use the AVR, 120hz is no longer an option. Frankly I expect that to be the case with a lot of AVRs, they're likely to strip any uncommon modes from the EDID "just to be safe"
To fix it, I used the radeon control panel to add a custom resolution, used the basic 1080p settings and just changed the refresh to 120 (leaving everything else as is), and afterward it worked fine. I'm sure Nvidia has a custom res option too, but have no idea how to use it.
