Ok so, really really long shot but I guess you guys are my “only” hope.

I want to activate HDR mode with my 2018 macbook pro 15" connected to a LG B7 OLED TV.

can anyone with the same setup confirm that you get a HDR option when they connect their tv? I tried catalina and bigsur now, bo dice nada no option pops up …

Same hdmi cable works on appletv, windows pc and the usb-C to hdmi adapters (all 3 ! ) work on a lenovo laptop for HDR…

I will try to borrow a original apple usbC to hdmi adapter next (that thing is 80$ or something… wow)

I even tried to connect a fake edid hdmi splitter that works on all other devices and shows “hdr” just the macbook… nothing dead. Accordung to apple it should work.

What I want to try is to comp on a HDR screen using nukes new experimental “EDR” feature where they send a extended sRGB signal to the monitor hoewever that works (i want to find that out) , its liek srb but in float.

I’d try [SwitchResX](https://www.madrau.com) before changing cables. Sometimes this software makes miracles when it comes to display connected to mac. Never tried it with something related to HDR thou. They had time-limited demo available

yea I tried that even just sending 1080p to the lg its all 10bit and the same cable work on all the windows devices , but on macos no dice no hdr option at all, also tried the new m1 macbook pro and also no hdr option .

I got a friend with the official apple adapter maybe that will work.
