Anandtech published ASUS MX299Q Monitor
A quote from the article:
The panel does not make the monitor. As I saw in my last 21:9 monitor review, even if you have the exact same panel in two displays, a whole lot more makes the display good or bad. One might assume that all the 21:9 displays now hitting the market are likely to be similar, or even the same, since they all use the same panel, but they would be greatly mistaken as that is but a small part of the overall display. Because of this I was looking forward to seeing what ASUS could manage to do with a high quality panel at its disposal for their MX299Q monitor.ASUS MX299Q Monitor Review @ Anandtech
