Hello, Tanishq Khatri
Welcome to the Microsoft Community.
It sounds like you're having problems setting the correct display resolution on your monitor.
I'll give you some steps, here's a step by step approach to trying to fix this:
Step 1: Check the monitor connection
Physical connection: Make sure the monitor is properly connected to the PC via VGA or HDMI or DP cable. You can replace the cable and test to see if it is a cable problem.
Step 2: Check the display Settings in Windows
Right-click on the desktop: First right-click on an empty area of the desktop.
Display Settings: Select "Display Settings" from the context menu that appears.
Adjust resolution: In the display Settings window, you should see a list of display resolutions. Look for the one you want (1280x720 or 1366x768) and select it.
Refresh rate: Make sure the refresh rate is set to 60Hz(or the maximum supported by your monitor).
Apply Settings: Tap "Apply" to apply the new resolution and refresh rate Settings.
Step 3: Update the graphics driver
Device Manager: Right-click the Start menu and choose "Device Manager" to open the Device Manager.
Display Adapters: Expand the Display Adapters section.
Update driver: Right-click an AMD Radeon graphics card (in this case, Ryzen 5 5600g integrated) and select "Update Driver".
Automatic search: Select Automatic search for updated driver software.
Windows will search for the latest driver updates and install them when available.
Restart your computer: After updating the driver, restart your computer to make sure the changes take effect.
In addition, you can also go to the official website to download the driver directlyAMD Ryzen™ 5 5600G Drivers, if you install the latest version cannot be repaired, you can install the old version of the driver mentioned in the link for testing.

Step 4: Install the monitor driver (if applicable)

Additional tips:
