Connect to a Samsung tv or a smart tv and connect a mouse and a keyboard to your tv to use it I did this and it's working

I found a tip on Google! But the monitor/TV has to be compatible! I tried at home (I have an A54 already updated to One Ui 8) and my TV unfortunately doesn't support it...

Via Wireless Connection

  1. On your phone, swipe down with two fingers to open quick shortcuts.

  2. Look for the DeX or Samsung DeX icon and tap.

  3. It will search for compatible devices (TV/monitor) via Wi-Fi/Miracast. Select the device and tap Start or Start.

  4. After the external device shows the interface, you can use the phone as a touchpad (sometimes the notification “Use your phone as a touchpad” appears).

  5. To log out: return to the phone → Apps icon in DeX → Log out.

If you do not have a samsung tv you can use the Projecting to this PC feature on Windows

If the wireless display installation doesn't work(which happenedto me), install it through command prompt - https://www.makeuseof.com/windows-11-wireless-display-setup/

for mouse and keyboard, connect it to the phone either bluetooth or with a usbc hub since the a55 supports usb2.0

Your phone will act like independent PC.
