Why do EVF specs list 1.44 million dots when the viewfinder is only 480,000 pixels?

My Panasonic DMC-G2 electronic viewfinder is advertised as 1,440,000 dots, but some reviews describe it as 480,000 pixels. Why are those numbers different, and what’s the right way to compare EVF resolution between cameras?

Actually it is slightly more misleading. 480,000 pixels normally equals 1,440,000 dots but they do get away with only 480,000 actual dots (not pixels) by using something called field-sequential display which is basically 480,000 dots which change colors very fast, sending information for each primary color sequentially.

There are only 480,000 dots but since they send three colors sequentially, it is considered 1,440,000 dot 'equivalent' and therefore equivalent to 480,000 pixels.

EVF makers often count color subpixels (“dots”) rather than full image pixels. A full-color pixel is usually made from three components: red, green, and blue. So 480,000 pixels × 3 subpixels = 1,440,000 dots.

On some displays, especially field-sequential designs, the same display elements may rapidly cycle through red, green, and blue and be marketed as a higher “dot equivalent” figure. That’s why you may see wording like “1.44M dots equiv.”

For comparing cameras, pixel count is usually the more meaningful number than dot count, because dot count can be a marketing-friendly way to inflate the spec. In this case, 1.44M dots generally corresponds to about 480k full-color pixels.

So the short version is: nothing magical is happening—manufacturers are often just counting the three color components separately. When comparing EVFs, try to compare actual pixel resolution, and also consider magnification, refresh behavior, eye point, and overall clarity, since those affect the viewing experience too.
