ASUS is making a smaller, cheaper version of its ROG Swift PG278Q G-Sync display. It doesn't even have a product number or full specs yet, but we can say it will be 1080p and 24'' (as opposed to 2560 x 1440 resolution and 27''), and sports a fast response rate TN panel. And while it will, on the whole, be a downgrade, the refresh rate should be higher. Currently, it's employing a 144Hz refresh rate, but ASUS says it wants the release model to go to 165Hz.
The new model should launch sometime this year. We'll keep you posted on the final specs and price.
