A desk perpendicular to a window often provides useful side light while keeping the monitor away from a direct window reflection.
Quick answer
Confirm glare, heat, curtain operation, chair support, cables, and the route from the door before settling on this angle.
Tune the side light
Place the monitor so the strongest daylight comes from the side, then use an adjustable blind for low sun. Left- or right-side light may matter for handwriting and dominant hand.
Create support without closing the room
A wall or orderly backdrop behind the chair can feel stable, but allow ventilation and enough movement. A freestanding desk may work when the chair still has protected clearance.
Review door and cable paths
The user should not sit in a collision point or trail power leads across the entrance. A modest rotation can improve the door view without losing window light.
