Hi everyone new to the board.  Hoping you can help me out having a big problem.  I'm using an Alienware X51 with an NVidia graphics card on Windows 10 operating system for gaming.  On my brand new 70 inch Vizio tv when I use the DVI port with a HDMI converter to plug into the HDMI input on the TV I get a "no signal" message.  I rolled back the graphics card driver and got the same message.  I re-updated the drivers to the most current version and it worked for about 30 minutes then dropped the signal and back to the "no signal" message.  The onboard intel graphics HDMI port works fine however for the gaming that I'm using it for it will not work as it is not powerful enough.  The graphics card port DOES work on other TVs.  The Vizio is the brand new TV in the living room and I don't want to become a stowaway and just be in the office when I want to play games so it MUST work on the Vizio!!

 

 

So far I have tried a ton of different HDMI cables and they don't work with the computer but will work with other devices.  I know next to nothing about computers so if anyone has any suggestions or instructions please be VERY specific in what I have to do.  I have done some searches on line and this problem seems to come up often but never seems to have the same resolution so I don't really know where to start.

I tried to add this to my first post but it doesn't seem to be showing up.

One really - possibly - stupid question. Have you selected the correct HDMI input on the TV ?  No offence intended, but it is surprisng how often silly things like this get overlooked.

:) Yes the correct input is selected.  It worked for 20 minutes then dropped the signal.  It's working again now but in the next 30 minutes I can guarantee it will drop it again.

I will see if I can get a more expert opinion. My only experience with connecting computers to TVs is with my wife's laptop, and that works perfectly every time! So no help there.

Whenever troubleshooting GPU issues with Windows do this first:

 

First, download the latest Nvidia Drivers

Then, download this: Wagnard's Display Driver Uninstaller - this is a GPU driver cleaner, it will definitely remove your GPU drivers, unlike official uninstallers. Note: There are some deceptive ads on the forum page.

 

  • Run Wagnard's DDU - it may create a number of files in the same directory, like a .zip file, so you may have to run it in its own folder
  • Run the application, "DDU.exe" I believe is the name
  • Select the "best option", Safe Mode and Reboot
  • After the computer reboots to safe mode, run DDU if it does not open automatically
  • Choose the "best option", clean install and reboot I think it is called
  • After restarting install the AMD driver you downloaded first
  • Restart if prompted

 

Nevermind. Noticed you tried that already.

 

Which TV model is it exactly OP?

Can you provide the model of the television set?  Odds are the manual for the TV will provide a clue as to the issue.

OP mentions he/she connects it with a DVI to HDMI adapter. Maybe the DVI signal is not communicating exactly like a pure HDMI connection?

Hey everyone thanks for trying to help sorry for the late response.  It's a Vizio D Series.  My wife hates keeping manuals which drives me crazy!  I'll try to get the exact model number some how later today.

The manual just tells me to select the correct input which it's already on the right one.

It may be a combination of HDCP 2.2 and the DVI to HDMI adapter.  HDCP will break your video if anything in the chain is not HDCP 2.2 compliant.  Have you tried to use all of the different HDMI ports?
