A warm welcome here in the Roku Community, @Kelleyty!
We appreciate you reaching out for support. No worries! We're here to find you the best resolution regarding the display issues you've observed.
Before we proceed, could you please provide us with a photo of it for reference? So we can assess your concern better and provide you with an accurate resolution. Also, what model is the TV that your Roku Express 4k is connected to? Can we please try to plug it into a different TV to see if the same issue occurs?
We'll be anticipating your response!
Best regards,
Carly
