Hi @Rav94,

Thanks for your first post in the Roku Community!

We understand that you are having trouble getting the 4K resolution in your Onn Roku TV during casting with your Windows 11 device. We are more than happy to provide you with more information about this.

Before we proceed, could you please tell us what content you are trying to cast from your Windows 11 device to your Onn Roku TV? We need to make sure that this content supports 4K resolution as well. In addition, the common cause of not getting the correct resolution during playback is the network connection's signal strength. Ensure your Wi-Fi connection is stable and performing well. Sometimes, even with fiber optics, fluctuations in speed or signal strength can cause delays.

Furthermore, please make sure that your Windows 11 device is already showing in 4K resolution before casting it from your ONN Roku TV.

Please let us know if this information helps you with your concerns.
