I have several TX92 TV PCs connected to TVs for streaming, and to monitors for use as thin client workstations with Windows. I recently upgraded, getting the same android box for each use. What I want to do with the one where I do my work, is buy and connect a 49 inch 32:9 aspect ratio monitor. I have several questions. Can I do it? Will the aspect ratio magically appear in the list of available aspect ratios in android settings? I use "Resolution Changer" (google play) to change resolution and DPI for phones, TV PCs, and the BlueStacks emulator for Windows. Can I make the monitor work using that? The TX92 comes rooted from the factory. A 32:9 aspect ratio will let me have two Windows sessions side by side, each 1920x1080, or I can do a Windows session and still have plenty of screen left for android applications. I use "Taskbar" (google play) for the launcher and to run windowed android apps.
TX92 has android 7.1.2, 2 gig ram, 16 gig storage.
I don't know what communication exists through the HDMI port. Connecting different devices causes different resolutions to be available in android settings, 4k TV vs monitor. That's why I think the resolution may magically appear when the wide monitor is hooked up.
The TX92 manufacturer has a nice website but has not replied to many inquiries.
