One of the most remarkable features of the Nvidia Shield TV is its capability to stream games from your PC onto the big screen at resolutions up to 4K 60FPS.
Some oddballs aside, the Shield TV has been able to deliver output consistently.
But these interloping errors can make your day a little bit demanding when it suddenly pops up out of the blue.
Most issues you may encounter while streaming through GameStream are due to firewall intervention and outdated software. A quick reinstallation of the software can help resolve the issue. Make sure to update the software and the drivers on your PC. Establishing a proper connection is also vital for optimal performance.
I'll now discuss in detail the causes and possible remedies for such inconveniences.
Requirements for Gamestream to Work on Shield TV
Knowing your what's what and how's how is crucial before jumping to conclusions.
If you don't know the requirements, you may have issues with the stream. Make sure you meet the requirements.
PC and CPU requirements
Nvidia has put out a minimum compatibility list that is necessary to operate the GameStream feature on your computer.
The list specifies that the CPU must at least be an Intel i3-2100 or an AMD Athlon II X4 630.
It requires an Nvidia GPU of GeForce GTX 650 or higher. 4 GB of RAM is recommended(regardless of the type).
The PC must be operating on Windows 7 or higher.
Generally speaking, the higher the specs, the better.
Network connectivity is of the utmost importance when talking about streams and streaming devices. Make sure you have a good connection, preferably above 6 Mbps speeds. Again, the higher, the better.
Also crucial is to connect both the devices to the same network. If not, the Shield TV or the computer may not be visible to each other during the pairing process.
Connecting through an Ethernet cable on both devices is recommended to avoid network lags and high latencies.
If you plan on using a wireless connection, try to connect to a 5 GHz bandwidth connection. The standard 2.4 GHz connection is susceptible to higher latencies and dropped connections.
Turn OFF VPNs enabled on your devices to avoid further problems. VPNs generally limit the speeds and cause latency fluctuations which are not ideal while streaming.
If you are having issues with the internet, you might want to look into Internet issues on Shield TV.
Turn OFF antivirus softwares on your PC
It is recommended to turn OFF or disable the antivirus and network protection software on your PC.
Some antivirus software tends to block access to the GeForce Experience app, which houses the GameStream feature.
If disabling the software doesn't seem to help, try uninstalling it. Softwares like Razer Synapse, Kaspersky, and Keybots need to be completely removed from the system.
Update the Software
Running on the outdated versions may prove to be unruly. Make sure you have updated the necessary software on your devices to avoid the plethora of problems that can arise out of primitive software.
To update the Shield TV, follow these steps.
1. On the Home screen, click and open the Setting icon.
2. Select Device Preferences and then click and open About.
3. Click on System Upgrade to manually update the device.
You should also frequently check and update the Nvidia Games app on the Shield TV
Next, you have to update the GeForce Experience software on the PC. Simply open the app and check for updates under the Settings/Preferences tab.
If you have updates left for Windows, complete them and restart the device, and then access GameStream.
Windows Defender issue
If you are unable to access the GameStream feature on your PC, it may be because of Windows defender's intervention.
In that case, try disabling Windows Defender. If you don't want to disable the firewall, you can grant access to the required applications that enable streaming.
Follow these steps to allow access to the necessary applications.
1. Open Windows Defender on your PC.
2. Click on Settings and select Exclude files and location.
3. Then, locate the file location of Nvidia. Generally, C:\Program files\NVIDIA Corporation.
4. In that file location, select the folders containing streamer.exe and container.exe. Generally, NVStreamSrv and NVcontainer folders.
5. Click on Add to allow access.
6. Select Save changes and then Exit the application.
Now, try accessing the GeForce Experience and try connecting through GameStream.
Logging out and Uninstalling GeForce Experience
Getting error codes  or  with messages "Cannot connect PC"? These error codes are associated with network and login issues.
Try logging out of your GeForce Experience account and then log in again. Check if this was helpful. If not, try forgetting the Shield TV by going to Preferences and clicking on Forget devices.
You will now have to pair the devices again. Follow the pairing process on both the devices and enter the code that appears on your Shield TV interface onto the PC to complete these up.
If you still have issues with the application, try uninstalling the app(GeForce Experience). When you remove the application, make sure you have completely removed it by deleting the Root folder also(NVIDIA Corporation).
After a quick reboot, install the software once again. Make sure to not remove any ancillary driver/application that comes with GeForce Experience software.
Update Nvidia Drivers
Some problems may be so persistent that you may have to resort to a much more technical solution. Updating the Nvidia drivers may be one such solution.
Download the right driver updates suitable for your Graphics card from the Nvidia website.
To update the driver on your PC, follow these steps.
1. Open Device Manager on your PC(from the control panel or by searching on the Start menu).
2. Click and open the Display adapters option and then click and expand Nvidia.
3. Double tap on the driver from the directory and select the Drivers option on the new window.
4. Select the update driver option and select the "Browse my computer for updates" option.
Restart the PC after updating and then try connecting the devices.
In the same window(step 3), you will have options for rolling back the updates and uninstalling the driver.
If you were not able to benefit from updating the driver, try rolling back the driver to a previous version.
Finally, if none of these changes helped, try uninstalling the driver from your PC. Make sure you have logged in through safe mode before proceeding to uninstall.
Reinstall the driver by downloading the latest version from the Nvidia website.
Clear the cache on Shield TV
On the Shield TV side of things, you can try and log out and log back into the Nvidia Games Hub app.
If that doesn't help, try clearing the cache of the Games app. If your Cache is overflowing, the likelihood of bugs and errors sprouting up on your device is very high.
Clearing the Cache memory can make the device much more efficient. To do so, follow these steps.
1. In the Home screen, click and open the Settings icon.
2. Navigate and select Apps.
3. Click on the Nvidia games app.
4. Click on the clear cache option to free the cache memory.
Restart the device and try streaming now.
You can also try uninstalling the app if clearing the cache was unsuccessful. Click on Uninstall while in the games app window in step 4.
Restart the device and then reinstall the app from the play store.
Sometimes, the problem may not be with the GameStream itself, it may be due to issues with other ancillary aspects of the Shield TV.
One such peripheral that may cause problems on the Shield TV is the Joystick. If you are having issues with the game controller, check out this article on Controller issues on the Shield TV.
Resetting Shield TV
As a final straw, try factory resetting the Shield TV. Hard resetting the device will remove all the dormant bugs and stale files, which usually remain even after an app has been removed.
To reset your Shield TV follow these steps.
1. In the Settings tab, click and open Device Preferences.
2. Click on Reset.
3. Select Factory Data Reset.
4. Finally, click on Erase everything to confirm the process.
Wait for the process to complete. Follow the setup procedure and log into your Shield TV.
