TV type is now passthrough by default

-- `3` - TV type will be autodetected
+- `3` - Console native TV type will be used
 
 Use this setting to force specific TV type.
-By setting value `3` bootloader will try to guess TV type from loaded ROM header.
+By setting value `3` bootloader will passthrough TV type native to the console.
 This setting is not used when **BOOT_MODE** is set to `3` or `4` (direct boot).
