Hello,

I am currently using the Orange Pi Zero 3 with Android 12 TV (32-bit), and it works incredibly well! I use this device to play retro games on an NTSC CRT TV. The Orange Pi Zero 1/2/3 and Orange Pi Zero 2W all feature an AV output, which allows me to stream and play retro games on this setup via Steam Link.

However, I am experiencing a rather strange issue. Even though the signal outputs in NTSC and fills the entire CRT screen, the Android system treats the internal resolution as 720p. To get around this—since I only use this setup for emulation—I configure the emulators to force a full-screen image. This workaround works perfectly in RetroArch, both natively on the Orange Pi and when streaming through Steam Link.

The problem arises when I try to play older PC games (for example, Prince of Persia: The Sands of Time). The game runs at 640x480, and Steam Link automatically preserves the aspect ratio. As a result, it adds black bars to the left and right sides of the image, even though my TV is already a native 4:3 screen.

As a potential solution, it would be amazing if we could manually control or change the aspect ratio settings directly inside the Steam Link app. Having a "Stretch" or "Fill" option for the stream would allow users in my situation to fully utilize the display area.

Thank you in advance for your time and attention!
