Good afternooon,

I have a superb monitor but Imac only recognizes a terrible resolution.
Any information to improve this?

Thanks in advance.

Camilo

What I meant to say is that I have this very problem with a Dell U3014
and a Mac Book Pro running Catalina 10.15.4 .
2 x HDMI over Thunderbolt3/USB_C --- both screens suck in YCbCr
 mode.

Interestingly, I had it with a U2410 too and could fix it with a 
firmware upgrade there.

Has anyone seen a FW upgrade for the 3014?

Good morning @andreas
I have been using this procedure 
https://www.imaccanici.org/forum/viewtopic.php?t=30799 for years in 
order to add the resolution hidpi 1920x1080 on the LG 27 EA83-D using 
this file on my mac mini
Today I discovered your amazing script patch-edid.rb
How can I mix the two different files so that I can have both RGD and
hidpi relosution?

Thanks
