How to test a webpage meant for Retina display?

Question

I have coded a webpage meant for retina display. I currently do not have a retina display monitor.

Is there any simulator application or tool to test web pages for

Answer 1

There is a JavaScript Web Retina Emulator on GitHub.

You can also use Opera Mobile Emulator to test for custom resolutions. There's an explanation of how to do it here.

If you have an older Apple computer (without a retina display) you can simulate retina displays with Quartz Debug, a tool inside XCode. Also in XCode you can test for iOS devices with retina displays using the iOS Simulator.
