TVHow Far to Sit From a 45” Monitor
36–52”
Comfortable eye-to-screen distance for a 45” monitor (91–132 cm) — about an arm's length.
For a 45-inch monitor, keep your eyes about 36–52” (91–132 cm) from the panel — roughly an arm's length. The top of the screen should sit at or just below eye level so your neck stays neutral. At this size, 4K / ultrawide so text stays crisp keeps text and images crisp without forcing you to squint or sit too far back.

Monitor arms & desk stands
A monitor arm sets the correct eye-level distance and frees desk space. Check the arm's weight range and VESA fit, and prefer gas-spring arms for smooth, tool-free height changes.
