Screen resolution on Nexus 4 and Nexus 7 If I understand this answer correctly, then the Nexus 7 (7" screen at 1280x800) should show more of a given webpage (or of anything else) than the Nexus 4 (4.7" screen at 1280x768). This means that a Nexus 7 will not simply look like an enlarged Nexus 4? It will appear to have a higher resolution, because of the "dp" value mentioned in that post?

I have a handset similar to the Nexus 4 and am considering a Nexus 7. However, if the Nexus 7 will appear as a larger version of my current handset (that is, what I see on screen at the moment will still appear on a full screen on the Nexus 7), then the purchase may not be worth it.
How the webpage is displayed depends on your choice of brower and your settings. Chrome on my devices by default displays webpages by width in desktop mode, so I see the same content horizontally on my phone and Nexus 7. But I'd say the web browsing experience on Nexus 7 is much better than on a phone due to the large screen, you can definitely see more on the Nexus 7 (vertically).
