The no flicker + grayscale feature release exposed underlying issues with some customer displays.
This was resolved by our factory for upcoming components, but previously affected customers may experience occasional washed out images:
This guide provides a quick method to adjust your display's tuning and resolve the washed out effect without new hardware. An alternative to this guide is enabling Maximize Compatibility.
Step 1 - Disable OTA Updates
Visit your device settings and disable OTA Updates. Make sure to click Save.
Step 2 - Flash the Beta Release
Visit usetrmnl.com/flash and select your device, then "FW1.6.8-temp-profile-beta," following instructions to add this build to your device.
Note: the "temp profile" feature is currently available for TRMNL OG and the Seeed DIY Kit devices.
Step 3 - Send us a live chat
Either in our developer-only Discord server or the bottom-right live chat widget on our website, let us know you'd like to opt into the Temperature Profiles beta.
We'll enable the feature on your account, and you may then visit your Device settings and toggle between multiple profiles.
Step 4 - Test each profile
After our team has enabled this feature on your account, we suggest first trying Profile A, then B, and so on. You may want to take a photo of each result.
To test a profile:
Select and save the profile from your Device settings
Drag and drop a washed out item in your Playlist to be the "next" item. Do this by ordering it after the row with a green "Displayed now" badge (example below)
Click the button on the back of your device to force-skip to the next screen
Observe results
Repeat Steps 1-4 for each profile until you find one that looks best on your device. Send us a live chat to share before/after photos, which we'll use to generate additional profiles.
