Acer's CE270K G is a 26.5-inch 4K QD-OLED monitor, and it is listed at $599.99 at Amazon, down from $699.99. That anchor is not a phantom, because Acer's own store sells the same part number at $699.99 and shows it in stock.
So the Amazon listing sits $100 below Acer's own price, and no Prime membership is needed to get it. The trade is refresh rate, since this panel runs at 120Hz where most 4K QD-OLED rivals run at 240Hz.
Acer sells the CE270K G as an entertainment and office display rather than a gaming one. That distinction is the point of the deal, because it is the cheapest route to a quantum-dot OLED panel at this resolution right now.
What the $599.99 Amazon listing covers
Amazon shows the monitor in stock, with the buy box held by Amazon.com rather than a marketplace seller. The listing carries a 14 percent savings badge against the $699.99 list price.
There is no used or open-box offer anywhere on the page. The $599.99 figure is the new-condition buy-box price, not a refurbished one.
Acer's US store lists the same display under part number UM.GC0AA.G01, still at $699.99. Acer's Singapore store carries the fuller spec sheet for the CE270K G.
Acer CE270K G specifications
Acer says the panel is QD-OLED rather than WOLED, and rates it at 1,500,000:1 contrast. Acer puts peak brightness at 1000 nits on a 3 percent window, with 250 nits typical.

How it compares with other 4K QD-OLED monitors
Three 27-inch 4K QD-OLED monitors sit close to this price at Amazon. All three were sold and shipped by Amazon.com at the time of writing, with no marketplace seller in the buy box.
| Monitor | Panel and refresh | Price |
|---|---|---|
| Acer CE270K G | 26.5-inch 4K QD-OLED, 120Hz | $599.99 |
| ASUS ProArt PA279CDV | 27-inch 4K QD-OLED, USB-C | $699.00 |
| Samsung Odyssey QD-OLED G8 (G81SF) | 27-inch 4K QD-OLED, 240Hz | $699.99 |
| MSI MPG 272URX | 27-inch 4K QD-OLED, 240Hz | $799.99 |
Samsung and MSI charge $100 and $200 more for twice the refresh rate. Samsung's listing also shows the steeper cut, at 46 percent off a $1,299.99 list price.
ASUS asks $699.00 for the ProArt PA279CDV, which adds USB-C that Acer does not list here. Acer prices have been moving for a while, and its Predator X27U W1 QD-OLED fell to $314.99 in a recent Amazon deal.
Panel discounts have been broad across the category. The Samsung Odyssey OLED G6 dropped to $602.33 with a 360Hz panel, and the KTC H27P6 dual-mode 4K monitor landed at $260.09.
What the listing leaves out
The Amazon page does not list a single port. Acer's own pages fill that gap with two HDMI 2.1 inputs, two DisplayPort 1.4 inputs, an audio line out and a headphone jack.
Brightness, contrast and PIP or PBP support are all missing from the listing as well. It also contradicts itself on size, pairing a 26.5-inch title with a 27-inch bullet, where Acer publishes 26.5 inches.
Acer publishes no burn-in or image-retention warranty for this model, and its US store warranty field says only that a limited warranty agreement applies. Response time is quoted as 0.03ms gray to gray with no measurement method given, and Acer's own US spec table muddies that by listing a 0.01ms to 0.03ms range instead.
No dual-mode option is published anywhere, so 120Hz is the ceiling. Prices are as of October 5, 2026 and can change without notice.
