All fine for me after a few weeks use. What is PWM ?

No issues for me but I've never been sensitive to PWM-related flickering. I've seen reports about it though so you're not the only one.
Pulse width modulation. It’s a method used for speed and brightness control. Basically the thing is switched off and on quickly and that action reduces the brightness or speed of a motor or fan etc.
The downsides are that some people are sensitive to it and see it as flickering. It’s also why things like screens canlook like they are flickering when being filmed with a camera.

It’s really bad for me which is gutting as I love the machine it just literally makes me feel I’ll using it. Tbh I have never noticed any issues before so no idea why I’m so sensitive this time. I have an iPhone 13 pro which is meant to be really bad for it but no problems using that. Maybe it’s the frequency ?

Yes it is. These are 14.8 KHz, which is quite low. Typical MacBook screens are about 120KHz. Now while MiniLEDs perform differently to PWM compared to fluorescent backlights (i.e. the numbers don't directly compare), this difference is still noticeable. When these MacBooks were released people who used previous MacBook without any issues were experiencing these problems.
It’s a pain literally I just cannot use it without getting headaches and nausea. I’m going to have to return it which is a bugger as it’s perfect really. The screen is stunning too just not in tune with my brain…..
No idea what to replace it with.

i had similar issues with the 2020 MacBook Pro I bought. Ended up returning it and buying a MacBook Air instead which didn’t have the same issue thankfully

I have a base 16” in silver coming today. It will replace my iMac which has been fantastic. I just need something I can work on in different parts of the house.

Crack on.
+ VAT. Cheaper than my partner discount and I don't think Very will get this spec in stock to make use of their 20% discount.
Congrats! Hopefully it ships pretty quickly.

Didn't notice those times initially. Seriously RIP @ChrisD. I hope you are happy with your Air
Keep the order. Once you find an alternative way of getting one, then cancel. Apple doesn't charge you until they ship.
They had a hold on my Amex for the amount, it was showing as pending.

AFAIK that’s how they work. They’ll put the hold on just to make sure they can take payment from the card. If the payment isn’t taken within 7 days the hold will disappear - until about 48 hours before shipment.
As @HACO said, keep the order, you’ve absolutely nothing to lose from doing so.
