Hello,
I decided to freshen up my old Dell Inspiron 620 so I can run triple monitors. It is primarily used for stock trading. I only run trading software on it, a few charts, word, and excel. I really just wanted to setup triple monitors as reliable and cheap as possible for now while I do more research and build a good trading rig.
Current specs:
i5 2320
Windows 7
8gb RAM
EVGA 750ti
EVGA Supernova 650W
3x monitors connected with Displayport MST
Now the problem is I've noticed mouse lag (I move it across the screen and it jumps to where I stopped rather than flowing with my movement, or it is very slow at selecting/dragging objects) and keyboard lag (keystrokes aren't registering).
I used speedfan and monitored the temps closely when I'm using all the software, Core temps rarely rise to 40c, and are usually around 25-35c. GPU temps stay around 35c.
What I've noticed is that running dual monitors with the onboard graphics card has absolutely no issue at all and runs flawlessly. Switch to the 750ti with dual monitors and it does the same lagging with decreased performance, never mind with all 3 monitors connected.
