 +===== 3) Test desired screen modes  =====
 +
 +  * You can test RTG screen modes from the ''​ScreenMode Preferences''​ of AmigaOS.
 +  * You should use resolutions and refresh rates that work best with your monitor or TV.
 +  * We recommend using 1280×720 or 960×540 for the best AmigaOS experience.
 +  * If you have a Vampire Standalone, make sure you test 720x576@50Hz and 720x480@60Hz,​ to ensure that your monitor or TV works well with them. The Vampire outputs non-RTG screens using these two screen modes. (The former in PAL mode and the latter in NTSC mode.)

 +
 +===== Creating new screen modes =====
 +
 +The SAGADriver package already installs some commonly-used screen modes. But if the provided screen modes are not sufficient for your needs, you can create your own:
 +
 +  - Open a Shell window (''​newcli''​).
 +  - Run ''​umc <​width>​ <​height>​ <​refresh_rate>​ <​nowiki>​--</​nowiki>​rbt''​.
 +    * For example, if you want a 720x576@50Hz screen, run ''​umc 720 576 50 <​nowiki>​--</​nowiki>​rbt''​.
 +    * You can request any resolution from 320×240 up to 1920×1080, and any refresh rate up to 60Hz.
 +      * Resolutions higher than 1280×720 will reduce the maximum refresh rate to 24Hz.
 +    * You will be given the appropriate mode settings.
 +  - Run ''​SYS:​Prefs/​Picasso96Mode''​.
 +  - Create a new resolution.
 +  - Enter the width and height.
 +  - Create a new mode.
 +  - From the output of ''​umc'',​ take the values under ''​Picasso96Mode values''​ and apply them to the settings of the newly-created mode.
 +  - Select the color depth you want.
 +    * ''​Chunky (256 Colors)''​ is 8 bits/pixel.
 +    * ''​HiColor''​ is 16 bits/pixel.
 +    * ''​TrueColor''​ is 24 bits/pixel.
 +    * ''​TrueColor & Alpha''​ is 32 bits/pixel.
 +  - You can create multiple modes for the same resolution, each with a different color depth. Just make sure that the mode settings come from the output of ''​umc''​.
 +  - Test all of your newly-created modes before saving.
 +  - After rebooting, the new screen modes will be available in the ''​ScreenMode Preferences''​ of AmigaOS.

 +<callout type="​tip"​ icon="​true">​
 +-> If you have a Vampire accelerator board connected to a classic Amiga, the line size must be aligned with the memory burst size, which is 32 bytes. In other words, the horizontal resolution multiplied by the color depth (in bytes) must be a multiple of 32.
 +
 +-> If you have a Vampire Standalone, the line size is independent of the memory burst, but it must still be aligned to 8 bytes. In other words, the horizontal resolution multiplied by the color depth (in bytes) must be a multiple of 8.
