Hello,

I'm running a Dual Monitor Setup:



Problem: I want to use the BenQ with 144 Hertz but when I try to set it on 144 the Samsung Monitor (1) turns black!
BenQ Monitor (2) is connected via DVI to my GPU (setup below).
Samsung Monitor (1) is connected via VGA with Displayport Adapter to my GPU. Is this maybe the reason for the blackscreen? And is there a solution to use my BenQ Monitor (2) at 144 Hertz and leave my Samsung Monitor (1) be as it is (60 Hz)?
At Samsung Monitor (1) I just have VGA + HDMI but I can't use HDMI to my GPU due to a connection with GPU and TV-Screen --> just VGA possible and my GPU does not have a VGA Slot. Help! :)

My System:
RAM : G.Skill TridentX 16 GB DDR3-2400 Kit (2x 8 GB)
Hardd: Samsung HN-M101MBB 1 TB
Samsung 840 EVO 2,5" 250 GB, SSD
Power: Be Quiet! Powerzone 650W
CPU : Intel Core i7-4770K @4 GhZ
GPU : Sapphire Radeon 290x Tri-x OC 4 GB
Motherb: MSI Z87-G43 Gaming, ATX
OS: Windows 8.1


I hope someone can help me with this.

All the best
