Dawn theme Displays low photo resolution.

[AndreiGhetu]

Hello. Does anyone know how to remove the resolution limit for product photos in the dawn theme? The images I uploaded are 2048x2048, but the website displays them at 990px. Unfortunately, I can't find a solution anywhere on the Internet. Please don't say, "Try to upload them on a higher resolution", because it's not working. They are still displayed as 990px. I tried to divide by 1 instead of 4. It's better, but still not what I want. It still is not displaying the full resolution.
