The 27-inch ASUS ROG Strix OLED XG27AQWMG gaming monitor is $100 off at Amazon, bringing it to $549 from its $649 list price.
The deal post that flagged it called $549 the monitor's lowest price ever. It did not cite a price tracker, so treat that as the post's claim, and note that deal pricing can change after publication, as the post itself warned.
The product title lists a 1440p, 280Hz Tandem OLED panel with G-SYNC, FreeSync Premium, a 0.03 ms response time, DisplayHDR 500 and 99% DCI-P3 color coverage. It also lists a TrueBlack Glossy coating and a Neo Proximity Sensor. The listing says OLED Care Pro and that sensor reduce burn-in risk, the permanent ghosting that static images can leave on OLED screens. The post said reviews of the monitor have been strong.
The description is less tidy. It calls the panel a 4K WOLED and mentions a Frame Rate Boost mode running 1080p at 330Hz. That does not match the title's 1440p spec, so check ASUS's spec sheet before you buy.
The discount works out to about 15%. That is meaningful for a high-refresh OLED, a category where burn-in worries and price have kept many buyers on LCD panels. A discount does not change the glare trade-off. Glossy coatings give clearer pictures than matte ones, but the post noted that some reviewers found the screen not bright enough to beat glare from direct light.
The room matters as much as the price. A glossy panel rewards a dim desk and punishes a window behind your chair.
