Overview

Roku 4K players evaluate the connected display’s video capabilities through EDID. When connected through a Just Add Power system, the Roku reads the EDID from the Encoder. To ensure reliable 4K output without artifacts or tearing, configure both the Roku and the Encoder according to the product series used: MaxColor Series, Ultra Series, or Omega Series.

Set Encoder EDID

Use the steps below to configure EDID on the Encoder attached to the Roku player. Each product series includes the recommended EDID settings.

1. Log into the web interface of the Encoder connected to the Roku.
   • If the interface cannot be accessed, configure a route using:
     • Set a Static Route on the Router, or
     • Add a Static Route to a Windows PC
     so your PC can reach the Just Add Power devices.
2. Open the Video tab and scroll to EDID Settings.
3. Recommended EDID Settings by Product:
   • MaxColor Series
     • Startup EDID: Built In
     • Maximum Video Resolution: 4K60
     • Maximum Audio Format: Stereo or Multichannel
   • Ultra Series
     • Startup EDID: Built In
     • Maximum Video Resolution: 4K60
     • Maximum Audio Format: Stereo or Multichannel
   • Omega Series
     • Startup EDID: Built In
     • Maximum Video Resolution: 1080p60
     • Maximum Audio Format: Stereo or Multichannel
4. Click Apply.
5. The video may briefly drop while the updated EDID is applied. If the Roku does not adjust automatically, power-cycle it to force a new EDID read.

Encoder Adjustment (Only if Tearing at 4K60)

If you see tearing or artifacts at 4K60 on an Ultra Series Encoder, apply the following adjustment.

1. Open the Encoder’s web interface.
2. Press CTRL + ALT + ENTER to open the CLI.
3. Enter these commands in order:

   astparam s ast_video_quality_mode 3
   astparam save
   reboot

4. The Encoder will reboot and apply the change.

Important: Only apply this adjustment if tearing occurs at 4K60 on Ultra Series. MaxColor and Omega do not require this change.

Quick Tips

• Verify that Roku has selected the correct resolution after configuration.
• If issues persist, power-cycle in this order: Roku → Encoder → Decoder → Display.
• Ensure the HDMI cable between the Roku and Encoder supports 4K60 when applicable.

Result: With the recommended Roku, EDID, and Encoder settings, Roku 4K players deliver smooth, stable video and reliable audio across all Just Add Power series.
