I have an iMac 21.5 inch Retina 4K display. I am trying to connect it to Dell S2319H (1920 x 1080 at 60Hz).
According to Apple website, the iMac supports one 5120x2880 (5K) external display at 60Hz or two 3840x2160 (4K UHD) external displays at 60Hz.

I am using USB-C to HDMI adapter to connect my iMac with Dell S2319H. However the text on the dell monitor is blurry.

I also use this trick to force RGB mode but the text is still blurry.

Is it because iMac only supports 5k and 4k display?

If I connect iMac to Dell 4k monitor, does it resolve the issue ?
