Dual monitor setup problem(shutter/lag)

[ktn21]

Hello,



I recently bought a new Samsung S27D590 (27" 60 Hz) monitor, in addition to my old one (Samsung S27B350 27" 60 Hz). So I could use the dual monitor setup for video editing.


Day 1

I had my old monitor connected via HDMI-HDMI cable . And the new monitor connected VGA- DVI-I (Integrated digital & analog). And everything that I put on my second monitor(NEW): web browser, vlc player. Everything shuttered/lagged. But when I disabled transparency on the desktop, then everything ran smoothly.
Now when I decided to try a game (Total War: Rome II) with dual monitors, "Span displays with surround" option checked in NVIDIA Control Panel. Then I got to play for about 3 hours, when PC started rebooting. When I went back to the game, I got to play for about 15 minutes, when the PC reboots again. Afterwards when I tried to play it with only one monitor, then there is no problems.

Day 2

I decided to switch the second monitor cable from VGA(blue)- DVI-I to HDMI- DVI-D And now there is ALMOST no shutter/lag on the second monitor when watching a movie or scrolling PDF files. And I didn't have to disable transparency on the desktop. But the second problem still remains, as I get to play the same game for about 3 hours, when PC starts rebooting.



While playing this game, my GPU usage is 70-80% and temp: 50-60°C. While CPU usage is: 50-60% and temp: 40-50°C.

I also updated the GPU driver, but it didn't help.


My rig:


Processor: Intel Core i5-4440 Haswell Quad-Core 3.1 GHz
Motherboard: ASRock H87 Pro4
Memory: 2x Crucial DDR3 4GB 1600MHz
Video Card(s): MSI GeForce® GTX 970 GAMING 4G
Hard Disk(s): Samsung 850 EVO Series 250GB SSD/ Hitachi Deskstar P7K500GB
Monitor: Samsung Syncmaster s27b350 27" / Samsung s27d590 27"
Power Supply: Corsair VS Series™ VS650
Software: Windows 7 64x Ultimate

Back of the GTX 970

I appreciate any help that you can provide,

Chris

I had same problem, because i my main monitor was 1920x1080 but secondary was really 1280x720 but i forced it to same as main, so put resolutions on recommended at windows settings.

But the thing with my problem is that they both originally are 1920x1080 monitors, and the resolution is already "recommended" at windows settings...

OKAY!
just making sure you werent over burdening the GPU!

I see both monitors only have VGA and HDMI inputs.

Is it possible to have both monitors running from VGA to DVI to the video card?

Or can you get a DP to HDMI converter? This way you'll have both monitors making use of their HDMI ports and on the GPU side you'd be using the HDMI and DP (HDMI to DP converter).
