Thank you for your reply.
However nothing happens on second, third, and any following attempts to set this particular resolution. I've tried DisplayPort and HDMI outputs and different displays (including 40" FullHD Philips LEV TV) but the behaviour is the same. Any other resolution works except for exactly half the native resolution of the display.

I think there's an intermittent bug where the first time you try to change the resolution, it fails. The second time should succeed, whatever resolution you pick the second time.

Guys, please remember this is code from around 2012 that I didn't wrote, I just organized it to be packaged in this repo. I'm not maintaining the code, just the packaging.
Someone needs to step ahead and update it to newer macOS APIs and machine models.

This RDM works for me in my MacBook 13” 2015 either for the internal Retina display and for my samsung external HDMI monitor.

I have exactly the same issue with 2560x1440 DELL UP2516D. The ideal resolution is 1280x720 HiDPI but when selected nothing happens.

I faced the same problem with High Sierra, and this appears to be a macOS bug, according to the SwitchResX FAQ (I see the same error):
I want to use a HiDPI resolution that is half the native size of the monitor, but this doesn't work
In some cases, you will see a resolution that is half the size of the native resolution of the screen. Selecting it will not work.
If you look in the Console (/Applications/Console), you'll observe a message like this one:
11/11/14 10:35:56,465 WindowServer[123]: CGXCompleteDisplayConfiguration: Monitor 4304241; Mode -1569958512 not available
11/11/14 10:35:56,465 SwitchResX Control[174]: CGSCompleteDisplayConfigurationWithOption
This is a bug within OS X itself. OS X reports this resolution as available when building the resolution list, but doesn't let you select it. There's nothing to do at this point, and SwitchResX cannot avoid showing this resolution in its list.

Hello, thank you for your reply:)
I have followed the instruction of this thread
https://comsystoreply.de/blog-post/force-hidpi-resolutions-for-dell-u2515h-monitor
After [disabling the system security via safe mode, overriding *.plist file
for my monitor(with the vendor#), enabling the security],
I was able to see the correct list of resolution in the RDM, and I was able
to select certain resolution which I couldn't select before.
After all, getting pieces from different places helped, and thank you very
much for RDM.
It's been really frustrating to use high def monitor with really low
resolution!
Have a great week
