Screen resolution error after doing system update

[Rogerudjshhs]

Hi, I have just done a system update, and I left for a moment, to give it some time to update, but when I came back, I saw a pop up message, saying a message about the screen resolution, it said, that I need to have the screen resolution of 1280 x 1024, or something like this, now, all I see is random colours, for a very little time, then the PC shut down. I have somehow managed to reset all of the screen settings, by clicking the screen buttons, but nothing is working. It says the input timing is not supported by the monitor. Can somebody please help me fix this issue. Thank you

I'm sorry to hear about the issue you're experiencing after the system update. Based on the information you've provided, it seems like the screen resolution or refresh rate settings have been changed to a value that is not supported by your monitor. To resolve this issue, you can try the following steps:
1. Start by booting your computer in Safe Mode: Restart your PC, and when it begins to boot, press and hold the F8 key until the advanced boot options menu appears. From there, select Safe Mode and hit Enter.
2. Once you're in Safe Mode, right-click on the desktop and select Display settings (or Screen resolution).
3. In the Display settings window, try changing the resolution to the recommended value of 1280 x 1024. You may need to experiment with different resolutions to find the one that works best for your monitor.
4. If changing the resolution doesn't fix the issue, try adjusting the refresh rate. Go to the Advanced display settings (or Display adapter properties) and select the Monitor tab. From there, you can change the refresh rate to a value that is supported by your monitor. Usually, a refresh rate of 60Hz is the standard.
5. After making the necessary changes, click Apply and then OK to save the settings. Restart your computer normally to see if the issue is resolved.
If the above steps don't resolve the issue, it's possible that the system update may have caused a driver conflict or compatibility issue with your graphics card. In that case, you may need to update or reinstall the graphics driver. You can do this by going to the manufacturer's website for your graphics card and downloading the latest driver for your specific model.
I hope these steps help you resolve the screen resolution error you're encountering. If you continue to experience difficulties, feel free to provide more details, such as your operating system and the model of your monitor, so that we can assist you further.

The problem is that it doesn't go in safe mode, the PC shuts down, after some moment, and this issues have been arising just after the screen resolution issue.

so looking at you have two screens yes?
try turning one off during the restart process until it boots to desktop, then you can turn it back on

No I have one, it is dell P1917s

 

[ussnorway]

[ussnorway]

i'd try replacing the screen with a temp to see if it boots, then if not replace the plug and finally the OS

Ah, that definitely complicates things! If your PC is now shutting down while attempting to boot into Safe Mode, it suggests that the issue may go beyond screen resolution. It could point to a graphics driver corruption, hardware fault, or even a power management glitch triggered by the system update.
Let’s focus on resolving this systematically, assuming you’re now dealing with a broader problem:

Steps to Fix Your System Without Safe Mode​

1. Use Advanced Startup Options​

Since Safe Mode isn’t working, you can use Windows' Advanced Recovery tools to address the situation:

• Access Advanced Startup:
• If the PC doesn’t boot at all, force shutdown your PC by holding the power button, then restart.
• After 3 failed boot attempts, Windows should trigger Advanced Recovery Options automatically.
• Alternatively, use a bootable USB installer (created with Windows Media Creation Tool) and choose Repair your computer.
• From Advanced Options:
• Select Troubleshoot > Advanced Options > Startup Settings.
• Enable Low-Resolution Video (640x480).
• Restart the computer.
• This forces the system to boot into a basic display mode, bypassing problematic resolution or refresh rate settings. If successful, go to Display settings and reset the resolution or refresh rate manually.

---

2. Roll Back or Reinstall Graphics Drivers​

If advanced startup works or you manage to boot with basic video:

• Open Device Manager (Win + X > Device Manager).
• Expand Display Adapters.
• Right-click the graphics adapter (e.g., NVIDIA, AMD, or Intel) and:
• Choose Roll Back Driver (if available).
• If Roll Back isn’t an option, choose Uninstall Device and ensure Delete the driver software for this device is checked.
• Reboot the PC to allow Windows to install default drivers:
• If this resolves the issue, go to the GPU manufacturer’s website and download the latest drivers manually.

---

3. Perform a System Restore​

If rollback/reinstallation isn’t an option due to shutdowns, use System Restore to revert to a point before the update.

• Access Advanced Options as noted earlier.
• Select System Restore and follow the prompts to restore to an earlier working state.
• Note: This only works if System Restore was enabled previously.

---

4. Test for Hardware Issues​

If your PC shuts down even before reaching recovery tools, there might be a deeper hardware issue worsened by the update.

• Monitor Behavior:
• Connect to an external display via HDMI/DP to check if the issue lies with your monitor or the PC itself.
• Check for Overheating/Power Issues:
• Ensure the PC isn't overheating—check that fans are working and vents are clear.
• Power supply issues can cause shutdowns. If you suspect this, test using another PSU (if available).
• Run Diagnostics:
• Many PCs have built-in diagnostics in the BIOS/UEFI menu (access via F2, F12, or other keys during boot).
• Run the diagnostics to check for failing hardware like the GPU, RAM, or power system.

---

5. Boot Using an External Recovery Tool​

If all else fails:

• Create a Windows Bootable USB using the Media Creation Tool on another PC.
• https://www.microsoft.com/software-download/windows10
• Boot from the USB and choose Repair Your Computer.
• From there, try:
• Reinstalling drivers via Command Prompt.
• Performing a complete reset or reinstall of Windows.

---

Bottom Line:​

Your description hints at a potential graphics driver or hardware issue exacerbated by the update. Start by enabling Low-Resolution Video through startup settings to regain control, or move to System Restore. If the PC still refuses to work properly, using recovery tools or external diagnostics might be required.
