Confirm the exact split-screen mode
Look up the supported local player count for the intended game mode and platform. A game may offer split screen in one mode but not another, or support different counts on different devices. A general multiplayer badge is not enough. Confirm whether additional online players can join the local group if that is part of the plan.
Check the screen division. Horizontal and vertical layouts distribute space differently, and the game may or may not let you choose. Each player's interface must fit within that portion. Text that is readable in a full-screen trailer can become difficult from the sofa once several views are present. Test the actual local mode where possible.
Arrange seats around the information
Have each player sit in the position they will use and read a menu, objective and small in-game label. Move seats or adjust supported interface scaling if necessary. A screen visible from the side may lose clarity or contrast depending on the display. Do not judge the whole arrangement from the central seat alone.
Keep controller cables, charging leads and furniture out of the movement path. For wireless controllers, pair and identify them before starting. Assigning a controller to a player can be confusing when everyone presses buttons at once, so follow the game's sequence. A small label or consistent color assignment can help a recurring group.
Test a busy scene, not only the lobby
Different views can contain different visual demands, and a game may use different graphics settings in split-screen mode. Judge the actual play experience rather than assuming single-player performance carries over unchanged. Check whether each player can follow the action and locate their own interface during a normal encounter.
Audio is usually shared in some form, so discuss how players will distinguish important cues and communicate. A headset arrangement should follow the platform's supported local-audio behavior; do not assume every connected headset receives an independent mix. If the picture or sound becomes confusing, a game designed around one shared camera may suit the room better. Choose the format that lets everyone participate comfortably, rather than maximizing the number of players at any cost.
