Layout View vs Map View Spatial Resolution Issue

[HMustapha]

My map view displays actual spatial resolution, but my layout view displays and exports a reduced resolution. I have ArcGIS Pro 3.6.2, but also had this issue on the version I had before 3.6.2. I've tested out switching DirectX 12 to DirectX 11 and OpenGL, but that doesn't change anything. I've also cleared the local cache and refreshed the layout view by pressing F5 and Ctrl+F5 (Set display options—ArcGIS Pro | Documentation). 

My goal is to get the layout resolution to match the map view resolution. I'd appreciate any and all feedback on resolving this issue; thanks!

Are you able to post a test file here (or send it to a colleague) to see if the behavior persists on another machine?  Checking the differences between settings on the two might help track down the issue if the issue doesn't persist.

Thank you for your response! I had been using a Cached Map Service and when I switched to an Image Service the issue resolved. Not sure if it was just a rookie mistake or if there is something up with my settings.

Information I received from Esi Support Services: 

• Cached image service draws from prebuilt tiles at fixed scales and fixed pixel dimensions. If the map/layout/export isn’t exactly at one of those scales, ArcGIS Pro has to resample the tiles, which can look softer or pixelated.
• Dynamic image service is rendered on demand for the requested extent and output image size so that it can match the exact output pixel grid more closely and often appears sharper at arbitrary scales.

Map view and Layout view are both screen previews; however, Layout view is drawing a page composition, and the map frame may be fit/rescaled differently in the UI so that the same imagery can look different simply due to display scaling and refresh/resampling.

If we need to work with the image service dynamically and use functionality such as the mosaic method, we can change the layer's mode. To change the mode, right-click the image service layer and uncheck Enable Cache View Mode. To use the image service as a cached service, check this option back on. 

For our future reference, we could try using the settings below for a better output:

• For the imagery layer: toggle Enable Cache View Mode and compare.
• In export: verify DPI and the resulting pixel dimensions (not just page size).
• If you must use the cached service, try to export at a scale that matches the cache scale to minimize resampling.
