Hey guys,

I'm using my hd tv via hdmi as the sole monitor for my Windows 10 desktop. However I keep finding when starting up PC after shutting down, that after the first 10-15 seconds the tv goes black as if the monitor has been disconnected. Ive tried unplugging the hdmi cable from to and PC then plugging in again, using a vga cable to PC and to instead, turning off tv, changing the input source on tv. But anything I try, I'm still not able to bring the image back. The only way I've been able to fix it is I've had to resort to turning the PC off from the mains (which makes me very uneasy as its not good to do so) and turn it on again, whereby it magically works fine with no issue second time round.

Is there anything I can do to prevent this from occurring (in display settings possibly?)

Thanks in advance

To address the issue with your HDMI connection causing the TV screen to go black after startup, try the following troubleshooting steps: 1. Ensure HDMI Connection: - Make sure that the HDMI cable is securely connected to both the PC and the TV. - Check for any physical damage to the cable and consider trying a different HDMI cable to rule out any potential cable problems. 2. Update Graphics Drivers: - Ensure that your graphics drivers are up to date. Outdated drivers can sometimes cause display issues. - Visit the manufacturer's website (NVIDIA, AMD, Intel) to download and install the latest graphics drivers for your system. 3. Check Power Settings: - Sometimes power-saving settings can cause the screen to go black...

Check Power Settings: - Sometimes power-saving settings can cause the screen to go black. Adjust your power settings to ensure that the screen doesn't turn off during use. - Go to "Power & sleep settings" in Windows 10 and customize the display and sleep settings to avoid the screen turning off unexpectedly. 4. Adjust Display Settings: - Right-click on the desktop and select "Display settings." - Ensure that the correct display is selected and that the resolution settings are appropriate for your TV. - Try changing the display mode (duplicate, extend, or PC screen only) to see if it resolves the issue. 5. Restart Graphics Driver: - Press Win + Ctrl + Shift + B on your keyboard to restart the graphics driver. This key combination refreshes the display and may help if there's a driver-related issue. 6. Test HDMI Port: - It's worth testing different HDMI ports on your TV or trying a different port on your graphics card to see if it resolves the issue. If the problem persists after trying these steps, it could indicate a deeper hardware or compatibility issue. Consider contacting your TV manufacturer or consulting with a technical support professional for further assistance.
