Suggestions need additional clarity for "Serves images with low resolution"

The logo image on https://c3.ventures is provided at 262 x 68 pixels. This matches the `style="width: 262px; height: 68px"` as well as `width="262"` and `height="68"` attributes on the image.

It's saying the expected size is 393 x 102, but there's no explanation as to why. The computed dimensions in the inspector are 262 x 68. I'm guessing this is due to a device pixel ratio of 1.5 being used by the test browser or something like that, but there's no information to indicate whether that might be the case. I don't know what DPRs are being tested with or should be supported as a best practice and when I click the link I don't see DPR mentioned at all, so if this is why the image is being flagged on the audit it seems like there's an opportunity for additional documentation.
