1. Ensure both images you've shot are as close as possible in terms of settings and the exposure triangle.

2. Find the largest decent TV or monitor you can get hold of that does reasonable colour and viewing angle, and full HD (1920x1080). Ensure it is in native resolution, and that it isn't doing too much sharpening itself in the display menu.

3. Crop your image to what you want to view in the same 1920:1080 ratio. The idea is you don't want to "zoom" later

4. AFTER cropping what you want to view resize using the same method to 1920x1080.

5. Display both images full screen and do a blink comparison.

6. If you want to "zoom in" repeat 3-5 for the area you want to zoom in to.

That's the cheap way that won't bankrupt you with prints.
