There are a few reasons you might see a "SD resolution is not supported" message:
Not an HD television
The Plex channel for Roku players currently only supports HD resolutions for the interface. This means that you need at least a 720p television to be able to use the app.
We're working to be able to support SD resolutions in the future.
If you're using your device with such a display, you can still make use our older, discontinued Plex Classic channel, which does support SD resolutions.

Not using HDMI connection
You may see this error if you have your Roku connected via composite cables. Please instead connect the Roku using a standard HDMI cable.
Roku set to wrong Display Type
If your Roku is set to the wrong Display type, you can encounter the message. In the main Roku device menu:
- Go to Settings > Display type
- Make sure you choose a 720p or higher setting
