How to screen mirror Android to non-smart TV?
I bought a https://www.global-electronic.ro/cablu-hdmi-usb-tip-c-2m-kruger-matz_15453.html?id=112 to mirror my Samsung Galaxy M11 to my non-smart TV, but I get no signal. The TV has 3 HDMI ports and with every single one, I get no signal.
Is it a setting that I have to change on the phone or maybe on TV?
The cable you bought is an https://en.wikipedia.org/wiki/Mobile_High-Definition_Link cable using the https://en.wikipedia.org/wiki/Mobile_High-Definition_Link#USB_Type-C_(MHL_Alternate_Mode) .
For such a cable to work the phone needs to include special hardware. Additionally the TV has to support MHL, too as it's HDMI socket has to be MHL-enabled.
The MHL web site contains a https://www.mhltech.org/devices.aspx?tid=1 . There you can filter for Samsung devices.
In my opinion MHL is today an outdated technology originally developed for phone with Micro-USB socket. You can also see that on the list of supported devices. The last Samsung galaxy phone that supported MHL is the Galaxy S5 released in 2014. The last Samsung device with MHL support I recognize was released in 2015.
