Running Windows 8.1
3 Asus VN248H-P (1920×1080) monitors each with an HDMI and VGA input
1 Asus PB298Q (2560×1080) with DisplayPort, HDMI and Dual-link DVI-D inputs
Sapphire R9 280X Vapor-X
Outputs: DisplayPort, HDMI, Dual-Link DVI-I, Dual-Link DVI-I
The monitors are currently connected as such.
1. VGA cable to VGA/DVI adapter to GPU DVI-D output.
2. HDMI cable to GPU HDMI output.
3. HDMI/DVI cable to DVI-I output.
4. DisplayPort cable to DisplayPort GPU output.
I can get 2 of the 248s to run together with the UltraWide. Independently all 3 of the 248s are capable of displaying a desktop in their current connections.
When trying to extend to the 3rd display you get the dreaded must disconnect a display message. Is the issue the VGA adapter? Would single-link vs. dual-link on the HDMI to DVI cable have any affect?
If I purchase a MST hub such as the CSV-5300H to split my DisplayPort output into 3 HDMI signals and plug the 3 VN248H-Ps into that using HDMI cables then connected my fourth monitor via either of the remaining ports on my GPU would that work?
If I was to purchase a CSV-5400 and add another VN248H-P to the 4th port would I then be able to plug my Ultrawide and a theoretical 6th monitor into the HDMI and 2 open DVI ports on the GPU? Obviously I will be purchasing corresponding connecting DP=> HDMI cables if going this route.
Been looking for some clarification on some of these things for a few days now with out really getting any concrete information. In my searching it seems that the GPUs with the DP, HDMI, DVI-I, and DVI-D ouput setup have a much harder time getting multi-monitor setups functional and I have not come across anyone running a six monitor setup like I’ve described in the last scenario here.
I’m very interested in one of the hubs as I am not necessarily tied to my current GPU and having a hub would certainly give me a lot of flexibility when it comes to purchasing an upgrade in the future or just using different monitor combinations.
I’ve scoured most of the forum threads here and I have the utmost confidence that Paul will be able to get me pointed in the right direction.
