Increase resolution on non-retina iMac

[bobsaget123]

I have a 27'' non-retina iMac and a new 12'' MacBook. I recently increased the resolution on my Macbook beyond factory standards using the method described in this thread, and it is great:

Has anybody tried doing this for a non-retina iMac? Was wondering if it would 1. be functional and 2. actually be desirable/worth doing.

Thanks

You can't. Your maximum resolution is 2560*1440.

The method outlined in that post accesses the HiDPI modes on a Retina screen that are not easily available to a typical user. Apps such as Display Menu achieve the same thing in a simple format.

Even if you could do it it would look awful displaying an effective resolution higher than the actual resolution of the display.

On a Retina display, the smaller pixels and HiDPI means it's hardly noticeable, since 1 HiDPI pixel is still larger than an actual pixel on the display. On a non-retina display, while possible using an app such as Display Menu, it would have a much greater impact on display quality.
