Gotta get rid of that old stock for the incoming new stock. Costco tends to be a little more aggressive than most with this. I'd predict sub$300 by June. Not saying people should wait, but it will get cheaper.

Is it really worth it for a first OLED purchase?

Yes, and if you don't like it, you have 90 days. Not really a big risk. $320 is an excellent price for an OLED monitor with these specs. It's not perfect but if you're not a tech snob, you'll probably love it.

I'd say sure, as mentioned, it's Costco so you have a fairly good return window and while this is online only you can return to stores.

That said it is Acer, which is known as more of a budget friendly choice, but it's not like it's a no-name brand or anything. Other panels absolutely will be brighter, but that is an issue that largely depends on where your monitor is, i.e. is it next to a window? in really bright room? But even a lower end OLED will probably look better than your average non-professional monitor. All these 1440p QD-OLED panels are the same 3rd gen ones from Samsung anyways, same pixel arrangement, same True Black 400 HDR rating, the largest difference is going to be the stand, the ports on the back, the screen finish, and internal software with the menu system. And more importantly, these are on sale now because the new generation of panels are coming out, so yeah they won't be quite as good as the full priced ones that will be hitting shelves somewhat shortly, but if it's your first OLED you'll probably still be blown away.
And again, it's Costco, if after a couple months you don't really find it's any better what what you got, return it.

Why are Acer's models so poorly named? Literally looks like someone in their product department had a stroke and fell on the keyboard.

Anyways, what's the difference between this and the W1? I'm struggling to find what the W3keyboardgobrrrrrrrr is compared to others.

These recent days of being able to get a 1440p 27-in QD-OLED for $350 or less are amazing. I have used this opportunity to buy several different models, two for myself, a couple for my children and one for my grandson, various makes and models that have popped up here on Slickdeals. The models I have bought have ranged from this one in this deal the Acer X27U and I also bought a previous deal here The X27U A1, both models have a bunch of alphabet soup after those model numbers that are very confusing and frustrating, Acer needs to do a better job as far as model numbers to prevent confusion.

I also bought an AOC Q27G41ZDF 27-in QD OLED monitor that popped up on slick deals and was available on eBay with a coupon code in page for $221 although it didn't last long but I got one. All of these monitors replaced various 27-in entry level basic VA or IPS panel gaming monitors. I'm not an expert on monitors but I am a long time PC gamer and while I like certain things on some better than others, I can say I'm thrilled with the products that I received. One I kept for myself was the Acer Predator X27 A1 That was featured here on Slickdeals and available at Costco for $349.99 with free shipping.

Any of them are quantum leap above the MSI 27-in 1440p 170 Hz IPS panel monitor I was previously using. Some people are concerned about the brightness on these but all of them that I have or my kids have are in light controlled environments and they get plenty bright. I kept the model I mentioned for myself because I use a RTX 5090 and that model has a 280 Hz maximum refresh rate versus the 240 Hertz that the others have and that little extra bump is appreciated and that one has a tad more peak brightness in HDR But I find the brightness to be more than acceptable on all of them.

That AOC that popped up for $221 after coupon code although a factory refurbished unit sold on eBay with a 2-year Allstate warranty is probably the best deal I have ever seen. The seller is actually AOC themselves and go by a different name on eBay. It arrived well packaged in it's original box and the one I got was a 10/10 cosmetically and is a great performer in gaming, my grandson loves it. I know text quality is a concern on these and I really can't give much of an opinion on that since I use a MacBook for work, these are used primarily for gaming with newer AAA titles.

I think it's great that these are now more affordable than ever and hopefully it stays that way. I don't think you can go wrong with any of them IMO.

Just note this is the 240hz model, the 280hz model has been at $349.97 for a while now. The 280hz one also gets brighter than this one.

Usually there is some rhyme or reason that people familiar with the stock could decode rather easily. In this case . . .

Model: Predator X27U W3bmiiprx

27In UltraHD Widescreen . . . to display a beta Mii on a Subaru PRX. It couldn't be simpler.
