I have two monitors which both support Full HD resolution, i.e. 1920x1080 screen resolution.
When I enable AMD Eyefinity for a game, it sees screen resolution as 3840x1078 instead of 3840x1080.
Video card is ASRock Radeon RX570 Phantom Gaming D OC 8GB.
AMD driver is the latest available WHQL driver – 23.11.1.
The games which I used to find this bug:
- OpenTTD 13.4 installed from Steam;
- Tom Clancy's The Division 2 installed from Ubisoft, the latest version.
Two screenshots showing the bug are following.
