The selection takes place immediately, so if you have a panel connected, you should see valid output on the display.

Note that if you change resolutions, the display memory will likely have mis-aligned data in it. Displaying a bitmap on the display through the use of the fatload and bmp commands will remedy this situation. Refer to init.script for an example.

If you want to make your selection stick through a reset, you can save it through the set and save U-Boot commands.
