Smart Fit Firmware Update Available
The Optoma UHZ35ST now supports Optoma’s new Smart Fit / Custom Screen Type firmware feature, giving users more flexibility when setting up the projector with custom screen sizes, golf simulator impact screens, and non-standard display layouts.
This firmware update adds Optoma’s Custom Screen Type function, which allows you to add a custom resolution to the projector’s EDID table. By doing this, the projector can better communicate the intended screen format to your connected source device, making it easier to fill non-standard impact screens and achieve a cleaner image fit.
- Better fit for simulator screens: Helps fill custom impact screens more effectively, especially when the screen does not match a standard 16:9 shape.
- Custom resolution support: Adds a custom resolution to the projector’s EDID table for improved source-to-projector communication.
- Cleaner image geometry: Helps reduce distortion caused by forcing a standard resolution onto a non-standard screen.
- More usable screen coverage: Helps maximize the projected image area across your impact screen.
- Improved pixel efficiency: Helps maintain sharper image quality by using the available pixels more effectively.
Firmware update requirements: A USB-A to USB-A cable and a Windows PC are required to complete the update.
Availability: Firmware can be downloaded through the Optoma product page or direct firmware link below
