Dear Sir / Madam, I just got a Asus 31.5" 4K monitor PQ321Q. My PC is quite new (Intel Core i7-4770K and 16 GB) and has one AMD Radeon R9 290 (4 GB) and 2M displayport 1.2 certified wire from Accell is connected to the monitor. It was set to MST mode and restarted. However, on both AMD Catalyst Control Center and PC's screen resolution on desktop, it is shown that the resoultion is 3840x2160. However, in reality, it is 2560x1440, when I checked the resolution online. I have the updated driver from AMD. AMD Catalyst Control Center - Information - DisplayPort Diagnostics, the total bandwidth is 20.76Gbps and the bandwidth usage is 86%, which is equivalent to 8.9 Gbps each on both display at 43%. It is said taht Internal hub in use, 1920x2160 (75Hz) Max on both.
If you have some ideas what causes the problems, could you please kindly point me in the right direction. Your help would be greatly appreciated. Thank you in advance. Ricky
