How this is calculated

The diagonal, 190.5 cm, sets a 16:9 screen of 166.0 cm by 93.4 cm. The 75 and 77 are close in size, but they usually come with different panel types. Most 75-inch sets are LCD models, like QLED, which pair an LCD panel with a quantum-dot layer and a backlight. OLED sets usually come in 77 inches instead, and each pixel makes its own light. The two screens differ by only 5% in area, so the picture type is the bigger choice.

Verdict

Choose 75 inches for a big living room where the sofa sits within 3.1 m (10.2 ft)10.2 ft (3.1 m) and the wall takes the extra width. The panel measures 166.0 cm (65.37 in)65.37 in (166.0 cm) by 93.4 cm (36.77 in)36.77 in (93.4 cm), or about 15,507 cm² (2404 in²)2404 in² (15,507 cm²) of picture. At 4K it's 59 PPI.

Against the 77-inch, the 75 is about 1.7 inches narrower on the screen. Pick it when the wall is tight or when an LCD set suits your room better.

Frequently asked questions

What seating distance suits a 75-inch TV?
A 40 degree view is 2.3 m (7.5 ft)7.5 ft (2.3 m) away, and a 30 degree view is 3.1 m (10.2 ft)10.2 ft (3.1 m). A sofa in that band gives the reference views, and a seat nearer than the 40 degree distance fills more of the screen.
Is a 75-inch TV too big for a living room?
Not if the seat is at least 2.3 m (7.5 ft)7.5 ft (2.3 m) from the screen. Closer than that, the picture fills more of your view than the 40 degree reference, and a small room can feel crowded.
What TV stand width do I need for a 75-inch TV?
Pick a stand or console at least as wide as the whole TV. The screen is 65.4 inches wide, and the frame adds to that, so use the spec sheet figure for the full TV. Check the top surface depth too, since the TV's feet need room.
How is a 75-inch TV different from a 77-inch TV?
