Adding/Using HiDPI custom resolutions

charliebounce said:

Any idea what is going on here @RehabMan? This not pick up any of these HiDPI resolutions!
I have added the `.plist`file extension to be able to upload the file here. It is located in folder `/System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-30ae`.

This is for a Lenovo L24Q-10 monitor. I have a DELL U2515H Display with the same resolution and it picks up the same HiDPI resolutions without any issues.

I'm use a Mac Pro 2008 with an HD5770 Graphics Card.

You should reduce the complexity of your plist by including only one HiDPI resolution.
There's no way I'm going to verify all that content...

Also, you will need to provide proof of where you installed the file (use 'ls' in Terminal).

Ok @RehabMan, please see attached files. I have simplified the plist to show only the resolutions I would like. Thank you!

Start with a plist that has only one custom HiDPI resolution.

Hi @RehabMan, just to let you know concerning by problem above. It has been resolved.
The problem was a limitation with the graphics card, namely the ATI HD 5770. It does not support such high resolutions. I have since replaced it with an Nvidia GTX 660 and I now have more than a dozen HiDPI resolutions to choose from. I didn't have to touch the file in the overrides folder, just swapping the card with a newer one was enough!

Thanks

Great.
Figured it was some sort of driver/hardware specific issue.

Though your method did not work on my computer (I don't see the HiDPi), this script worked very well.
it also adds some user-friendly scale settings in prefpane. maybe it would be helpful for some ppl

Confirmed, works well. I also received a scale settings in preferences panel.

Not agree.
Having a 4K (3840x2160) monitor, when I use the 2560x1440 supposedly native resolution, if I do a screen capture, and I get the details of the file, it shows 5120x2880, which is highly undesirable, as it is loosing performance (because of a bigger frame buffer).

Find attached the image, which is the file "get details" of the screenshot of the following resolutions: left is non native 2560x1440 low resolution and in the right 2560x1440 supposedly high dpi resolution...

Obviously is pretty bad and undesirable.

Have anyone tried to do screen captures of their desks and see the real resolution of it?????

That is exactly what you should expect. It is the way macOS HiDPI works. Your 2560x1440 HiDPI is rendered at 2x (5120x2880) then scaled to native (3840x2160). You should not expect to get this for free... it does impact performance.

If you want better performance (but less quality) set to 2560x1440 non-HiDPI.

If you don't like the way Apple implemented the feature, maybe you have a suggestion on the way they could improve it.

Thanks for clarify that. I think that the way apple implemented is really bad. I prefer to see it small icons and text rather than pay the performance price. Thanks!

EDIT: here they explained very differently, talking about native resolution, which is not true...
