27" S2740L IPS-LED Monitor Graphics Issue

I play PC video games and I recently set up two 27" S2740L IPS-LED monitors using DVI connections. I kept my system graphic settings the same (ultra) however; I changed the resolution to 1920x1080. I rarely, rarely ever experience lag even in high population video game scenarios.

After a few days, I purchased a long HDMI cable and connected it to the main monitor. After connecting the HDMI cable I turned on the computer and I was prompted to update the graphics driver. So through Microsoft's action center, I updated these drivers:

  • nVidia - Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.2, Graphics Adapter WDDM1.3, Other hardware - NVIDIA GeForce GTX 560
  • Microsoft .NET Framework 4.5.1 for Windows 7 x64-based Systems (KB2858725)
  • Dell Inc. - Display - Dell S2740L(Digital)
  • Intel Corporation - Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.2 - Intel(R) HD Graphics 3000
  • Dell Inc. - Display - Dell S2740L(HDMI)

Then I launched a video game to experience extremely lagging gameplay. I tinkered with several system settings adjusting different graphic options but nothing reduced the lag until I chose the "recommended" graphics settings. The recommended settings reduced the graphics settings to low quality and the resolution to 1280x720. *sad panda* Then for giggles I launched different video games and all graphic settings are set to low quality.

So I'm guessing this issue is related to a defaulted setting of somesort. Perhaps the HDMI port is only connected to the onboard Intel graphics card... If so, is there a way to switch it to the Nvidia card? Perhaps it is something else. Any suggestions?

I'm not sure if this is helpful but I included my system information below.

RE: 27" S2740L IPS-LED Monitor Graphics Issue

I just realized where I went wrong. The Nvidia card has two DVI ports only. The HDMI must be part of the integrated GPU then which is bad...huh. 

I reconnected the DVI cable so I'm running two DVI cables and I'm back to ultra and 1920x1080. I'm learning as I go and this all makes sense to me now. Thanks for helping it click.
