The app is missing the 512×240 optimal timing option in the drop-down box on each LineX mode. Can you update the app to include this new feature of firmware 0.82? Much appreciated!
Edit: This is also causing a bug: When you assign 320×240 mode in the app for each LineX box, the OSSC reads it as 512. When you assign 256×240 in the app, the OSSC sees that as 320. So it seems the missing 512 mode is causing a ‘shift’ in the OSSC’s recognition of optimal timing modes from the bin file.
