CLevo-170sm hdmi problem

Computer: CLevo-170sm chassis, Sager NP8278-S

windows 10 64bit

I'm having increasing problems with running dual monitors from my
sager. The external monitor is connected through HDMI and will sometimes
cut out for a few seconds then come back on. Once in awhile, the monitor will
turn off completely and the system will kick me back to the windows boot screen
for some reason and the external monitor will not work until restarted.
Whenever this second thing has happened I was watching Youtube vids. I don't know if that
is just a srange coincidence. Its slowly been getting more severe. On one recent occassion the laptop
completely failed to recognize different monitors from the HDMI port even when it restarted
and I thought it was completely gone until after about a day it suddenly recognized an external
monitor again for some reason.

When looking through the event viewer there is no obvious event associated before or during the times
when the monitor cuts out.

The closest I could find is an error slightly after the time the monitor fails which is listed as

I've updated the drivers for both the discrete card and the integrated graphics. But it
doesn't seem to have stopped whatever issue it is. What could be wrong?

 

Can you reinstall the chipset driver? Do you see any fluctuation in video output if you move the cable around (near the port and at various points along the cable)?

 

Have you tried using a different cable to the monitor, or moving around as mentioned? If there is some tiny break internally that could cause issues.

 

When the laptop quit working with the hdmi for a day it didn't respond to switching out cables. I'll try updating the chipset driver.

Where is the chipset driver for this laptop? I can only find a w8 version.

 

Windows 8.1 was the latest supported OS that Clevo published the driver for, but it might still work on Windows 10.

It could be a problem with the port, but hopefully not.
