Which is the best 24 inch external monitors for new M4 iMac?

If you want to save some money consider getting a Mac Mini M4. I got the Mini with a 3rd party 32" 4K monitor w/speakers for about $400 less than a comparably configured 24" iMac.

Just some food for thought.

Thanks! I'm looking for one without speakers or a webcam. I just want it to be comfortable for my eyes to move from one screen to the other, and I know I probably can't match the quality of the iMac screen, and its high resolution, on a second monitor that's 24 inches. Some people have mentioned the LG UltraFine, but that doesn't seem to come in 24". I'm looking at one of the Dells.

LG used to have a 24'' IPS UHD 4K UltraFine™ Monitor (model 24MD4KLB-B) that attached via Thunderbolt 3, and that had 98% coverage of DCI-P3. They discontinued it.

There's another 24" LG 4K monitor that attaches via less exotic means, and costs only about $300. This one is the 24UD58-B . There is no specification of sRGB coverage, only of NTSC coverage. That's usually a Bad Sign when it comes to color accuracy – and this monitor appears to be aimed at gamers.

The ASUS ProArt PA24US is a 24" 4K monitor that has 99% coverage of Adobe RGB, 95% coverage of DCI-P3, and a built-in colorimeter – features that might appeal to photographers. It lists for $1299.

That's all that I can find. You would think that given that 3840x2160 is the same resolution as Ultra HD TV, that there would be cheap, good, 24" UHD 4K monitors all over the place. But apparently not.

1. Both links are for the same monitor.
2. You will notice marled different in quality, since the monitor you link to is not 4K like the iMac's screen, it's a low 1080p.
3. I would go for a 27" to match the resolution of the iMac.

If you're going to get a M4 iMac and add an external 27" monitor why not just get a Mac Mini M4 and then get a 27" 4K or 32" 4K monitor for about $650 less than the similarly configured M4 iMac alone would cost. I know as I just got one with an LG 32" 4k monitor for $1417 whereas the iMac would have cost me $2065.

Just some food for thought.

Pretty much any monitor will work.

Its comes down to budget and specific requirements you may have of it like if you need it to be 4K or higher resolution. Refresh rate, color accuracy, wether it should be Smart or not, with speakers or web cam built in, etc...

I would suggest looking at Dell, Samsung, BenQ and even LG options.

You might find that there aren't as many 24" monitors out there with 4K or higher resolutions.

You can always get a 27" display or higher if you want. The physical dimensions of the iMac's display does not limit what you can output to.

We use Dell computers at work. Some people buy extra monitors for working from home. My employer's IT department rep told me he uses the Onn monitors available at Walmart. Inexpensive and maybe worth a try.

If the requirement is simply that the external monitor doesn't physically damage your eyes, that's a pretty low bar. There are lots of 24" 1920x1080 monitors that presumably will not damage your eyes.

But you're going to notice a difference in the quality of text when you set one side-by-side with a 24" 4.5K Retina iMac.

+1 I was thinking the same thing.

Get the M4 Mac mini and use one large 32" display or... two 24" displays that are the same.

It also depends on whether you have any special requirements like calibration or profiling. If not, see above.

There are literally hundreds of external displays that meet your requirements. I’d suggest that if you are the USA to visit Costco.com
