Frequently asked questions

Does a 65-inch 4K TV have more pixels than a 55-inch 4K TV?

Usually no. Both commonly use 3840 × 2160 pixels, but the 65-inch TV spreads those pixels over a larger physical area.

Is 65 inch a big upgrade from 55 inch?

Yes. The diagonal difference creates a clearly larger screen area and stronger viewing impact.

Which is better for dashboards?

A 65-inch display can be easier to read from farther away, but layout, font size, and viewing distance matter.
