Cannot get PC to display on TV after updating NVIDIA driver

[Sithinious]

My wife bought a new computer which we hooked up to our TV which she would use as the computer monitor. The computer displayed on the TV just as it should, until I updated the video card driver to an NVIDIA driver. Now the computer will no longer show up on the TV, though it will still show up when connected to a computer monitor. If I hook the HDMI cord back up to the TV and restart the computer, I DO get the initial booting screen showing the motherboard logo. But once it boots into windows, the TV shows the generic “no signal” screen.
unfortunately, the graphics card that came with the computer has only one HDMI port, so I cannot have it hooked to both the TV and monitor at the same time. If I could, I could mess around with the display settings and try to get it to recognize the TV as a second display. But as it is, I have to have the HDMI hooked into the monitor to change any settings, then unhook the HDMI and plug it back into the TV which is a real pain.

Any advice or ideas as to a fix would be greatly appreciated.

roll back the driver would be my first step

May I ask why you updated the driver if it was working ?

[Sithinious]

It was a new computer and had no NVIDIA driver. I know the reason it isn’t working is not simply because it’s an NVIDIA driver, her old computer also had an NVIDIA GPU with the latest drivers (or nearly latest) and it displayed fine on the TV.
A driver rollback will be my last resort if I absolutely cannot get results using an updated driver.

Are you positive that it has a NVIDIA card? If the new system does not have one, then installing the drivers for a nonexistent device will cause this issue.

Yes, an NVIDIA GTX 970.

Where did you get the driver from?

Did you get the proper one form the systems manufacture web site?

NIVDA is manufacture by several companies depending on who and which chipset makes a difference on where and what driver.

Some are even made for specific computer manufactures like HP Dell ASUS that have different specs than the NVIDA cards themselves.

Hmmm… I got it from NVIDIA directly, as I always do. But the card is a Zotac. It’d be really odd if they had their own drivers separate from NVIDIA, but it’s worth checking out. Thanks.

And risks something getting shorted out, only hot swappable devices such as external storage devices should ever be connected or disconnected when a computer is in use.

That is an eight year old card but in your OP you say that the computer is new, Zotac will have provided an installation disk when the card was new but the disk concerned will have only had at the latest Windows 8.1 drivers as the card pre dates the release of Windows 10.

Just a fyi, Zotac and others do not just sell their products to the general public, they also sell them to big box companies such as Dell and HP etc, they 100% do have different drivers because they modify the cards to reduce power consumption and heat, to do this they write their own drivers that reduce the GPUs performance and power requirements etc.

If you have still had no luck with this post back with the full specifications of the computer + the OS itself.

Well, I tried Zotac’s website and downloaded the driver for the video card And it’s a…. Drumroll please…. An NVIDIA driver. But not the same one I got when I downloaded it from the NVIDIA website. Unfortunately, even with the new driver I get the same result. Works fine when connected to the monitor, but when hooked to the TV and then rebooted, I get the motherboard logo and BIOS prompt on the TV but as soon as it boots into Windows I get “no signal” from the TV.

No drumroll will be forthcoming atm I`m afraid as the computer concerned is a big box brand namely Lenovo so we now need to know the model name or number of the PC itself so that we can check all of the specs and what drivers are available for the MB, reason being is that Lenovo like other brands dumb down GPUs so that they need less power which in turn means that they put in a weaker PSU, you need a minimum of a Gold efficiency rated 500W from a proven brand such as the Corsair RM range, EVGA or Seasonic, if the PCI-E slot is not getting enough power when the appropriate drivers are installed that is down to the MB and/or PSU and nothing to do with the GPU or drivers.

[Sithinious]

The PSU is 300 watts… I’m going to look for a better one. In the meantime I’ve rolled back the driver to the generic non-NVIDIA one that came with the compute, the PC is once again displaying on the TV (which is causing other problems because of this generic driver, not going into those here). Thank you very much for your help.
