Hello,
I also have two Dell Ultra-HD monitors (UP2414Q) set up for extended display on a buit system. The problem I am encountering is that only one monitor will display a resolution of 3840 x 2160. The other monitor offers no option beyond 1920 x 1080.
Here are the main components to my system:
CPU - Intel i7-4770K
Graphics card - NVIDIA GeForce GTX 780 SC
Motherboard - ASUS Z87 PRO Socket
RAM - 32 GB Kingston HyperX Blu
Windows 8.1 at 64-bits with all recent updates
I submitted some questions to an online forum at Tom's Hardware. The suggestion I received was to lower the refresh rate to 30 Hz in order to get Ultra-HD from both monitors. Also, it was suggested that I go into the BIOS to enable IGPU multi-monitor, then install the Intel drivers.
Do you view these solutions as credible?
Thank you.
