Does anyone can share sdr and hdr settings used with clr screen ?
I have gathered some settings in different forums and on some websites. With the new ProjecTivy Tools from XDA they are quite handy to use. PM me, i will send you a google docs link.

The Xiaomi is a great device (after having it fixed with the plate from [email protected]). With the latest ProjecTivy Tools from XDA you can setup different display profiles for HDR/SDR wich is a another great improvement.

The only thing which is bugging me is the coil whine. Interestingly the whine is almost not existent in 3D-Mode. In 2D-Mode its much louder when the light mode is set to "Movie" as opposed to "Hightlight" mode.

So i tried a solution with a modified Ikea tv bank as an encasement (see pictures attached). The solution is effectively eliminating the coil whine. But now i run into heat problems. I tried adding some usb powered pc fans, but after one hour in "Movie"-Mode i get a heat warning from the projector.

I think the biggest problem is the heat sink (see attached picture). Measured with a heat gun it is getting to ~55 degrees Celsius in Movie-Mode and up to 66 degrees Celsius in Hightlight-Mode. The other side of the UST where the two fans reside is only getting to ~22 degrees Celsius.

The thing with the coil whine is, it is originating from the side with the heat sink. So to block it of i have to enclose it but then i am running into heat problems. At the moment i am out of ideas regarding the coil whine.

Has anybody found a better solution regarding to the coil whine issue?
