Hi Arnou, your post has been moved to Graphics.
Do you know the driver version you are trying to install?
What type of cable are you using? Are you using any kind of adapter, converter, or AVR?
What are the display and motherboard models?
I have a simple installment. No any special converter, adapter...etc.
Motherboard: Gygabyte B85 D3H
Processor: I5 4460
Connected with vga cable to Samsung Syncmaster monitor.
I tried to install HD4600 from the Motherboard CD and the latest version from intel.com None of them work. Just a Win7 logo after startup.
I'm using it with 32bit, its perfect with that version.
May be the reason that i have only 1x 4GB DDR3 RAM (Kingston) ????
The RAM should not affect this issue.
Do you have the model of the Samsung Syncmaster monitor?
How is the monitor detected in Device Manager?
Can you attach the Intel® Graphics Driver Report?
A possible workaround could be using a different type of cable (DVI or HDMI).
