Samsung SyncMaster doesn't connect with PC
I got this Samsung SyncMaster P2370 from work, because they say it is damaged. The monitor starts perfectly and background lighting works, but the PC doesn’t react if I connect the monitor! The monitor shows an input-box icon and turns off after a while.
It has a DVI input and I use a HDMI-DVI-adapter and a HDMI-cable.
Anybody knows what’s going on or which parts I should check?
Thanks in advance!
