Receiving HDCP Error with no Video and Purple screen with HDCP error on Toshiba TV after upgrading to Roku 9.2. Followed all steps suggested on different forums and Roku site to correct HDCP. Roku works fine with same HDMI cable on other TVs in house. This Toshiba is compatible to 720p display type and not 1040p but it was working fine with this Roku until upgrade to 9.2 version.

I'm not sure if this will work for you, but it's worth a shot:
Go to Settings -> System -> Advanced System Settings -> Advanced Display Settings -> Auto-adjust display refresh rate if it's set to Enabled, set it to Disabled.
Thanks for your patience while we've investigated this issue. Please try checking for a system update in Settings>System>System update>Check now. We've released an update that should help address display issues that we've heard reported. Make sure to set your display type back to 'Auto detect' in Settings>Display type. If you still see an issue, double check that you have disabled 'Auto-adjust display refresh rate' in Settings>System>Advanced system settings>Advanced display settings.
Keep us posted!
Thanks,
