LG Flatron M2780D-PZ - "No signal HDMI"

maki · Oct 15, 2015

LG 27" Flatron M2780D-PZ (PC MONITOR TV)
twintech-geforce-gts-250-oc

"No signal HDMI" and black screen (It does not show up BIOS - (you can only hear that runs Windows)

I turned off the computer.
I went to sleep. In the morning I turned on the computer and shows me "No Sinal"
I have tried many things:
1. I changed the HDMI 1 to HDMI 2 - did not help
2. Re-I installed the NVIDIA drivers - did not help
3. Reset BIOS - did not help

I have other ideas ... what happened ..
Works only D-SUB

You need to try a different monitor to see if the monitor is the problem or your graphics solution. I would also try a different HDMI cable.

I do not have another monitor, and other video card.

I tested with another cable (HDMI) - without positive results.

Most TVs support computer input.

If you cannot find another monitor or TV to try, you will need to take the computer to a shop.

The monitor works D-SUB and others

The graphics card work two DVI ports

I do not know whether the monitor or the graphics card does not work in HDMI port...

but it seems to me that the problem is elsewhere.

because
as I connect the HDMI cable to HDMI - No Signal
as disconnecting the cable - Check the signal cable

The fact D-Sub works proves Windows and the rest of your computer is working. You already re-installed the drivers and tried another cable. So that leaves the graphics solution or the monitor is not working with HDMI. The only way to check is to try another monitor on your computer, or your monitor on another computer.

If you don't have another monitor or computer (with HDMI) to try, then you need to take it to shop or find someone who will let you test with their hardware.

Hello my friend.
Tell me, what are your options:
Select the shortcut Win + P

I do not understand what you are trying to tell us with your last post. It tells us nothing about your HDMI situation.
