The white ASUS ROG XG27UCGR-W is down to $369.00 on Amazon, and that is exactly what ASUS charges for it too. The saving is a price match with the maker, not a retailer undercut.
Amazon shows the 27-inch 4K monitor at 14% off a $429.00 list price. Amazon.com holds the buy box, so this is a first-party sale rather than a marketplace listing.
One line on ASUS's product page is worth reading first. It states that the lowest price in the 30 days before the promotion was also $369.00.
That does not make the price a bad one. It does mean it has been steady rather than fleeting, so there is no reason to rush.
The black XG27UCSR sibling costs $40 less
ASUS sells a near-identical model called the ROG XG27UCSR, and Amazon has it at $329.00. It is black instead of white, and Amazon.com holds that buy box as well.
The two are not the same panel, despite the matching product shots. ASUS lists the XG27UCSR as dual mode at 4K 160Hz or FHD 324Hz, against 162Hz and 485Hz on the white model.
Amazon's title for the XG27UCSR says 162Hz. ASUS's spec sheet says 160Hz, and the spec sheet is the better source.
So the extra $40 buys the 485Hz fast mode, a brighter typical output and the white finish. Anyone who does not need 485Hz should take the cheaper one.
ASUS ROG XG27UCGR-W specifications
These figures come from the ASUS spec page for this exact model code, not from the retail listing.
| Specification | ASUS ROG XG27UCGR-W |
|---|---|
| Panel | 27-inch Fast IPS |
| Native resolution and refresh | 3840 x 2160 at 162Hz |
| Dual mode | 1920 x 1080 at 485Hz |
| Response time | 1ms GTG, 0.3ms minimum |
| Brightness | 400 cd/m2 typical and HDR peak |
| HDR | VESA DisplayHDR 400 |
| Color | 95% DCI-P3, 130% sRGB |
| Contrast | 1300:1 |
| Video inputs | DisplayPort 1.4, HDMI 2.1, USB-C with DP Alt Mode |
| USB-C power delivery | 15W |
| Adaptive sync | G-SYNC Compatible, AMD FreeSync Premium |
| Stand | Tilt, swivel, pivot, 0 to 110mm height |
Switching between the two modes is manual. ASUS describes it as a tap of a hotkey, so the screen does not follow the game's resolution on its own.
The idea is now common at this price, as the KTC H27P6 dual-mode 4K monitor and the budget AOC dual-mode model both show. ASUS's 485Hz figure is the fastest of that group.
How the alternatives compare
| Monitor | Panel and refresh | Price |
|---|---|---|
| ASUS ROG XG27UCGR-W | 27-inch 4K Fast IPS, 162Hz or FHD 485Hz | $369.00 |
| ASUS ROG XG27UCSR | 27-inch 4K Fast IPS, 160Hz or FHD 324Hz | $329.00 |
| ASUS ROG XG27ACMES | 27-inch 1440p Fast IPS, 255Hz | $229.00 |
| LG 27GS93QE | 27-inch 1440p OLED, 240Hz | $499.99 |
The ROG XG27ACMES at $229.00 drops to 1440p and loses dual mode, which is the sensible saving for anyone not chasing 4K. The LG 27GS93QE at $499.99 trades resolution for an OLED panel and far better contrast.
One oddity is worth noting. The older Gen1 XG27UCG, which tops out at 4K 160Hz and FHD 320Hz, currently sells for $378.00 on Amazon, or $9.00 more than the faster new model.
For a sharper 4K panel at a similar price, the INNOCN CB27U1 at $379.99 is the nearest non-ASUS comparison covered recently.
What the listing leaves out
Amazon's bullets lead with a 0.3ms response time and never mention that this is the minimum figure. ASUS's own sheet also gives 1ms GTG, which is the more meaningful number.
The listing promotes USB-C with DP Alt Mode without saying that power delivery is only 15W. That will charge a phone, not run a laptop.
Neither the title nor the bullets state DisplayHDR 400 or the 1300:1 contrast ratio. On a 400-nit IPS panel, the title's claim of HDR for PS5 and Xbox is doing a lot of work.
A free three-month Adobe Creative Cloud subscription has been reported alongside the monitor. It does not appear on the ASUS product page or in the Amazon bullets, so treat it as unconfirmed.
ASUS does not publish a downstream USB port count for this model, and no end date is given for the discount. Both prices were checked on Amazon as of September 26, 2026, and retailers change them without notice.
