There are two easy ways to change your HUD Profile in PokerTracker 4. The first is changing your HUD Profile while playing or in the replayer. To do this, simply click the PT-icon chip, go to Change Profile, and select the HUD Profile you wish to use.
While playing, you can also select the Make Active Profile Default for Table Type to use the current HUD Profile for the table type you are on. So if you are playing a $1/$2 6max cash game and select the Cash - Legacy HUD Profile and click Make Active Profile Default for Table Type, the Cash - Legacy HUD Profile will be used for future $1/$2 6max cash game tables.
You can also click Hud from the main menu and select Edit Hud Options. This will bring up the Hud Options Configuration window which allows you to add definitions for certain HUD profiles. For instance, you could select to use the Cash - Default HUD while playing 6max games, use Cash - Legacy HUD while playing on PokerStars, and/or a wide variety of other definitions.
Simply use the appropriate drop-down menus to create your definition and click Add. You may also delete any active profile definition below by selecting it and clicking Delete. Once you have created all of your definitions, click OK to save your changes.
