Projectors
What is a projector's native resolution?
Native resolution is the real number of pixels the projector can display. Supported resolution is the highest signal it accepts through its input. A projector that is "1080p native and supports 4K" takes in 4K video but shows it in 1080p.
Why the spec sheet lists two figures
The imaging chip has a fixed number of pixels: that is the native resolution (for example 1280×720 or 1920×1080). Separately, the projector can accept higher-resolution signals and scale them down to display them. That is the supported resolution.
The sharpness you see depends on the native figure. The supported one only guarantees compatibility: that you can plug in a 4K source without the signal being rejected.
How you notice it
With more native resolution, text and fine detail look crisper, especially on large images or when you sit close. For movies at a moderate size, 720p native can be enough; for presentations with small text, 1080p native is the better choice.
The most common resolutions
480p: 854×480 pixels. 720p (HD): 1280×720. 1080p (Full HD): 1920×1080. 4K (UHD): 3840×2160. Each step multiplies the pixel count: 1080p has a bit more than twice the pixels of 720p, and 4K has four times those of 1080p.
What to check before you buy
- Always compare native resolution, not supported resolution.
- If you want it for text or spreadsheets, prioritize 1080p native.

Frequently asked questions
Not necessarily. It means it accepts a 4K signal. If its native resolution is 1080p, the image is shown in 1080p.
