The ASUS ROG Strix XG27ACMES is listed at $229.00 at Amazon at the time of writing, and the interesting part is what that figure undercuts. ASUS sells the same monitor for $299.00 on its own store, so Amazon is $70.00 below the maker.
That makes this a retailer discount rather than a manufacturer promotion being matched. The 18% badge on the listing is measured against a $279.00 typical price, which Amazon defines as the 90-day median price customers actually paid.
The hardware is a 27-inch 2560 x 1440 Fast IPS panel rated at 255Hz. ASUS says that top figure requires overclock, and the panel is quoted at 1ms GtG with a 0.3ms minimum.
What the $229.00 price is measured against
Amazon holds the buy box directly, with the listing naming Amazon.com as both shipper and seller. Stock is marked as in stock.
The $279.00 anchor is worth reading carefully, because it is not a manufacturer list price. Amazon states that the typical price excludes limited-time promotional prices, which makes it a record of real transactions rather than a sticker figure.
Measured that way, the saving is $50.00. For context on how crowded this bracket has become, a 27-inch 280Hz QHD Alienware panel recently fell to $199.99.
One caveat on the listing itself. The same product page carries a separate open-box offer from Amazon Resale, which sits below the main buy box and is not the price described here.
ASUS ROG Strix XG27ACMES specifications
| Specification | ASUS ROG Strix XG27ACMES |
|---|---|
| Panel | 27-inch Fast IPS |
| Resolution | 2560 x 1440 |
| Refresh rate | 255Hz, overclock required |
| Response time | 1ms GtG, 0.3ms minimum |
| Brightness | 350 cd/m2 typical, 400 cd/m2 HDR peak |
| Contrast | 1300:1 |
| Colour | 97% DCI-P3, 133% sRGB |
| HDR | HDR10, VESA DisplayHDR 400 |
| Adaptive sync | Adaptive-Sync, NVIDIA G-SYNC Compatible |
| Price at the time of writing | $229.00 |
Those figures come from the ASUS specification page for this exact model code. ASUS lists the refresh rate on the product page as 255Hz OC, and marks 144Hz as the point above which the overclock applies.
The response time deserves the same care. The 0.3ms quoted on the listing is a minimum figure, and ASUS separately publishes 1ms for grey-to-grey.
Ports, stand and the 15W USB-C limit
Connectivity is one DisplayPort 1.4 input with HBR3, one HDMI 2.1 port with FRL, and one USB-C port with DisplayPort Alt Mode. There is a 3.5mm headphone jack, and ASUS confirms the monitor has no speakers.
The USB-C port carries 15W of power delivery. That is enough to keep a phone topped up, but well short of the 60W or more that single-cable laptop docking usually needs.
The stand is fully adjustable, with 0 to 110mm of height travel, tilt from minus 5 to plus 20 degrees, 45 degrees of swivel each way and 90 degrees of pivot. ASUS also fits a 1/4-inch tripod socket and a 100 x 100mm VESA pattern, neither of which appears in the Amazon bullet points.
How the XG27ACMES compares at 27 inches and 1440p
| Monitor | Panel and refresh | Price at the time of writing |
|---|---|---|
| ASUS ROG Strix XG27ACMES | Fast IPS, 255Hz OC, DisplayHDR 400 | $229.00 |
| LG 27GS75Q-B | IPS, 180Hz, 200Hz overclock | $170.99 |
| AOC Q27G3XMN | Mini-LED, 180Hz, HDR1000 | $211.59 |
| LG 27GS93QE | OLED, 240Hz, 0.03ms | $499.99 |
The LG 27GS75Q-B is the budget route at $170.99, though it gives up 55Hz and its listing shows only three units left. The AOC Q27G3XMN is the closer fight at $211.59, trading refresh rate for a mini-LED backlight and HDR1000 certification.
Stepping up to OLED still costs roughly double. The LG 27GS93QE sits at $499.99, and a 360Hz Samsung OLED panel landed at $602.33 in a recent Amazon listing.
Cheaper 1440p options exist when refresh rate is not the priority, including a quantum dot GIGABYTE M27Q2 at $159.99 and a Dell 27 Plus QHD panel at $189.99.
Availability and the figures ASUS does not publish
ASUS quotes a 400-nit HDR peak without stating the window size used to measure it, so the sustained full-screen figure is not published. The Amazon listing is thinner still, omitting brightness, contrast, colour coverage and the DisplayHDR tier entirely.
The box holds a DisplayPort cable, power cord, ROG pouch, sticker, quick start guide and warranty card, with no HDMI or USB-C cable included. No end date is published for the Amazon price, and no verifiable price history was available to confirm how long $229.00 has been in place.
Prices at both Amazon and the ASUS store can change without notice.
