Afraid of purchasing the new Dell S2725QC

So, Dell recently launched what appears to be a successor of for their previous quite popular(?) model S2722QC. It is called S2725QC, a 99% sRGB, 65W USB C, 4K@120Hz, 1500:1 static contrast ratio 4K monitor. Pretty good on paper if you ask me.

As someone with M1 Air, and after weeks and weeks of delibration and lots of reading I thought this would be a perfect monitor for me.

Well, except, the flickering. As of couple of days ago I have been exploring the rather painful world of M silicon and external monitors flickering issues. ( https://forums.macrumors.com/threads/macbook-pro-m1-external-screen-flickering.2325279/page-9 )

Dell one was particularly affected by it.

However, this 2025 version of that model, might have fixed it? I don't know. What are your thoughts about it?

Dell 27 Plus 4K USB-C Monitor - S2725QC | Dell India

Shop the Dell 27 inch 4K USB-C Monitor with AMD FreeSync Premium, 120Hz refresh rate, dual 5W speakers, and 4-star eye comfort.
www.dell.com

I did contaact Dell about this and what they told me is that "It is not a macos compatible monitor so even if you experience flickering, you won't be able to return it"

I plan on getting a S2725qc within the first week of April. I’ve read DELL fixed it but I haven’t found anything that proves it. I’ve also read there has been a few improvements or “fixes” for the s2722qc. I’m assuming the 22 and 25 are relatively similar so I’ll try those methods in case it does end up flickering. The biggest one which seems to work for most people is “still color”. I own a m2 air, will try to see.

Thanks for the reply. I tried my hardest to find where Dell said they've fixed it but couldn't find anything. Apparantly, someone from reddit was saying the same too. Can you please post a source or something?

Also this makes me wonder, is there any 4K monitor at all in 350USD range that works with M Series Macs?

I’ll recommend the Viewsonic VX2776-4K-MHDU, my family has 3 of them and are quite happy with them.

Thanks for the recommendation. On my country's Amazon, I can see VA2709U-4K. However there are little no reviews of it available so I don't know if it'll work or not. Worse, if it doesn't I'll have to deal with the Service Center rather than Amazon just accepting my return because that's how Amazon functions these days.

There was a LONG thread in the forums about folks having trouble with Dell (and other) displays that started "flickering".

I don't think any "one size fits all" solution was ever found.

I'm going to GUESS that the flickering has something to do with a mis-match in the synch of refresh rates. Also seems to have something to do with the issue that the Mac is trying to feed a "yCbCr" (or something like that) color signal into the display rather than RGB.
Could also be a "combination" of the above 2 issues.

Sometimes changing the connection from HDMI to USBc corrects it. Sometimes not.
There are also ways to FORCE the Mac to deliver an RGB signal.

I'm using a Dell 27" 4k ultrasharp with an m4 Mini. Works fine.

Glad to know it works for you. I doubt M4 has any trouble anywhere.

Yes. I've read that thread, all 34 pages of it. And I know when there are 34 pages long threads it is not just a "vocal minority" but a real issue affecting real people.

From my understanding, there are couple of factors involved in the issue
1. Like you mentioned the non RGB output from mac
2. People using docks and adapters get different results
3. VRR troubles

I don't know whether it'll affect me or not. Normally, I would've just went ahead and ordered it but seeing how guarded everyone has recently become in India about returns, I'm afraid I'll have to stick with the faulty flickering monitor if they refuse.

I had tried LG 27UP850 earlier and found it very soothing and calming on my eyes. Despite text not looking as "sharp" and despite the quite visible backlight bleed on both lower corners. I had to return it because Amazon gave me an open box package with wrong serial number. Are these monitors at the end of their life though? Seems like such since they keep getting out of stock everywhere and LG's official website has also stopped selling them directly. The one I had received was made in Nov. 2024

I can’t really recall where I read it but I’ll try to find it. I also have mine coming in this week… hopefully it works

Yeah, I've also tried my hardest but wasn't able to find it. By the way mine is on the way too! ridiculous delivery time though, 4 more weeks. Looking forward to how it goes for you. Keep us updated!

Where is it being delivered that it's 4w out? I ordered Sunday with an ETA of tomorrow.
