u/N-I-K-K-O-R

I am using an iPhone 15 and when I tried to mirror to my Samsung s90f it was too laggy to play.

So I mirror the phone to my m2 MacBook Pro which is full screen. Then I hdmi out to the Samsung. This gives me a higher quality iPhone to Mac mirror quality.

Then use whatever Bluetooth controller to your phone. This kept the graphics as ok as possible for mirroring and removed a high percent of the delay lag. With the controller. Very playable like this.

Hope it helps some one
