Adding/Using HiDPI custom resolutions

[timdafweak]

Now you've just made the whole question/scenario that much more complex.
I'm not sure why you would want HiDPI for a server. Pretty images that important when configuring your server?

But I do think that HD630 (and other Intel graphics devices that Apple doesn't use) may not have enough power for a good HiDPI experience, which may explain why we haven't seen a MacBook Air with retina display. But there are also many ways to configure your system incorrectly in a way that makes it worse.

I've been running a headless Mac server for nearly ten years now. It allows me to have thin clients no matter where in the world I may be. The server runs all my profiles - and services + access to some IP restricted services like mail etc. Basically I do a lot of my work on the server, seamlessly.

When I upgraded to a retina iMac and MBP, remoting into a non-HiDPI server screen was a bit jarring.

Your hack allows HiDPI and man oh man is the experience so much better. Just a minor niggle that there is a bit more UI lag as I described earlier. For instance, the window redraw etc isn't milky smooth as it is on my iMac/MBP. Nothing that would make me revert back to the non-HiDPI days though.

You make a fair point about the HD630 and MBA screen. But what about the MacBook 12"? It does run off the HD615 I understand. I might need to revisit my config and see if anything there is set incorrectly.

I think MacBook9,x/MacBook10,x is 2304x1440.

I have monitor 1920x1080 at 144hz
but i just got HiDPi 1080p at 60hz, is it possible to do HiDPi 1080p at 144hz?

Off-topic.
This guide does not address refresh rate.

Note: 1080p is not HiDPI. A HiDPI mode needs to be some smaller resolution than native. For example 1600x900 on a 1080p monitor is rendered at 3200x1800 then downscaled to 1920x1080. It doesn't make any sense to render at 2x 1920x1080 for a 1080 monitor.

Thanks for info, but i followed the OP still can't get 1600x900 HiDPi. I tried SwichResX and add custom resolution but it says "Status" not installed

You will need to provide details on your hardware and provide proof you created the plist correctly and installed it to the correct file/folder location.

Hi Rehabman, I tried 1600x900hidpi on my 1080screen and it looks jagged a little bit. I also tried all smooth font option(1-4) but its still jagged. I notice that when I zoom the whole screen(Cmd+Opt++) text and icons look very good as I expected. What can I do for now?
p/s: screen looks verygood as 1280x720hidpi but icons too big

As you should expect.
3200x1800 does not scale perfect to 1920x1080.

Thank for your info. But why 2560x1440(1280x720 hidpi) scale very good?

The system is better with certain resolutions vs. others.
It is likely due to just the way the math works out.

The HiDPI scaling algorithms are designed for high resolution displays where the pixels are very small. With small pixels, the flaws are hard to notice. When the pixels get larger, it becomes more possible for humans to perceive the flaws.
