Automotive Device Display Resolution
Display resolution refers to the number of dots or "pixels" that a digital display can produce, which determines the amount of detail and clarity you see. It is typically expressed as a combination of horizontal and vertical pixels, such as 640 x 480, which equates to 640 pixels wide by 480 pixels tall.
The resolution of a device's display is different from the resolution of an image or video captured by a camera lens in a backup camera or dash cam. For example, a dash cam or navigator with built-in dash cam may have all of these resolution types:
a display resolution expressed in pixels
a camera snapshot resolution expressed in megapixels, and
a video resolution expressed in abbreviations such as HD along with a single measurement such as 1080p

All display resolutions are appropriate for navigation to provide directions as well as clear, scalable and readable maps.
Lower resolution can actually have advantages when it comes to displaying scalable maps, text, and lines. Lower resolution screens require less processing power, which can lead to faster response times and smoother performance.
Higher resolution is beneficial when using additional features such as video, aerial overlays for truck and RV arrival planning or topographic maps for dog tracking and trail navigation.
Some linked specifications mention TFT. TFT stands for Thin Film Transistor, a variant of LCD display technology used to improve image quality.
Abbreviations are sometimes used to describe display resolution. Here are some examples:
