Can't Run External Monitor at 60Hz

post #1 of 3
Thread Starter 
Greetings all. I'm stumped and can't find a similar thread. I tried to use my HDMI cable to connect an external monitor for the first time today. I cannot get it to work at the proper 60Hz on any resolution. When I try, the external monitor blinks on and off, there are horizontal lines, and sometimes everything comes through in pink tone. The VGA cable works just fine. I have tested the HDMI cable with another laptop and it seems to work fine.

Here is my setup:

Laptop -- Dell Precision M6600

GPU - Amd Firepro m8900
GPU Driver Version - 8.850.7.5000

Monitor - Dell U2410 native 1920x1200 resolution

OS - W7 Pro 64

I appreciate anyone's thoughts on the matter.

On modern digital monitors, you can't change the sampling rate. They always function at either 60Hz or 120Hz. Right? The refresh rate displayed on the screen is un-related bit-rate of the cable. Someone correct me if i am wrong.

"When I try, the external monitor blinks on and off, there are horizontal lines, and sometimes everything comes through in pink tone" This sounds like a bad or lose cable. You say the cable works with another laptop? Hmmmmm..... Try your laptop via HDMI on another monitor.

I have tested a different laptop with the same HDMI cable and monitor and they work together.

The displayport works and I am using it for now. I can't afford to RMA this laptop over a wonky HDMI port, if in deed that is source of the problem.
