Power BI service - Report resolution

Hi , dinesh123 

According to my research and testing, when you set the resolution of the Canvas to "Custom" type in Power BI desktop, you can set the size of the resolution for the report page canvas as you like, as shown in the image:

After publishing the report to Power BI service, you can also set the report to focus mode or full screen mode to meet your different resolution requirements according to your viewing needs, please refer to this document:
Focus mode and full screen mode - how to zoom in to see more detail - Power BI | Microsoft Learn

If it doesn't meet your report viewing resolution needs to some extent, you can hold down "Ctrl" + slide the mouse wheel to adjust the impression percentage size of the browser page for final adjustments

The above are all the methods to adjust the resolution of the report presentation in Power BI service under my understanding, please refer to and test, thank you very much!

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,

Aniya Zhang
