Hi,
I recently bought i5 3570k and radeon 7850, so the problem i am facing is that
mostly during GAMING(in dark backgrounds) i see some broad vertical lines.
 
my monitor is GL benq 2030 and it has a vga connection and i use the dvi to vga connector i got with the graphic card(radeon 7850).
 
To my surprise i didn't notice any such vertical lines when i connected the very same pc to my old CRT monitor,only with this new monitor i am facing vertical lines flowing upside down.
 
I have enabled tripple buffering and VSYNC in games that have that option, also lucid logic virtu mvp i got with asus board is also installed.
 
Please help me in knowing exactly what is causing this display issue and what can i do to have it resolved, either its graphic card problem or monitor problem,Please help me out.
 
thanks
Verify that GL benq 2030 REFRESH rate is 60Hz, under Control Panel--Display--SETTINGS--Advanced--Monitor
LCD/LED monitors are locked at 60Hz, CRT's could be set at various rates.  Plug & Play monitors should set this automatically.

Could also be a bad connection.  Does your graphics card have VGA or only DVI?

Your monitor has a DVI input, so why do you need the adapter?
