Here are some frequent screen problems and the corresponding fixes:

1. Loose cable connection

2. Malfunctioning graphics driver

3. Hardware malfunction  

4. Wrong refresh rate or resolution

Fixes from following HP Laptop Screen Issues problems :- 

1. Loose cable connection:- 
Here is a guide to troubleshooting issues related to a loose external video cable:

Signs of a Loose External Video Cable
A loose connection between your HP PC and monitor can lead to one of the following error messages: "No Signal," "Check Video Cable," or "Input Not Found." 

Key Symptoms:-

Intermittent Display:- The screen may randomly turn on and off, especially when the PC or cable is jostled.
Flickering and Artifacts:- You may see colored lines, static, or distorted colors, which might be momentarily resolved by moving the cable.

Inspect and Secure External Connections (Monitor Cable)
This is likely where the issue originates. 

1. Power Down:- Turn off both the HP PC and the monitor.
2. Verify the Port:-  If your PC has a dedicated graphics card (a larger card with ports at the bottom of the case), ensure the monitor cable is connected to one of those ports.
 If you’re using the motherboard's ports (located near USB and network ports) and have a dedicated graphics card, switch the cable connection to the graphics card.

3. Secure the Cable at Both Ends:- 
  Monitor Side:-  Disconnect the video cable (HDMI, DisplayPort, DVI, or VGA) from the monitor. Check for any bent pins or debris in the port. Reconnect the cable securely.
PC Tower Side:- Unplug the cable from the PC's port. Inspect that port for any damage and reconnect it firmly. 

If using a VGA or DVI cable (with screws), ensure the screws are tightly fastened.
If using DisplayPort, make sure the locking tab is properly engaged.

4. Power Cycle:- Turn on the monitor first, followed by the PC. Check if the issue has been resolved.

2. Malfunctioning graphics driver

If your screen is flickering or black, try these steps:

Step 1: Quick Driver Reset

Press  Windows Key + Ctrl + Shift + B on your keyboard.
Your screen will flicker, and you'll hear a beep. This means the graphics driver has restarted.

Step 2: Update or Roll Back Driver (If Screen is Black)

Boot into Safe Mode: 
Force shut down your PC by holding the power button for 10 seconds. Repeat this 3 times.
Your PC will enter the recovery environment.
 Go to Troubleshoot > Advanced options > Startup Settings > Restart.
 Press 5 or  F5 to select Safe Mode with Networking.
Update or Roll Back Driver:- 
  •     Open Device Manager.
  •     Expand Display adapters.
  •    Right-click your graphics card >       Properties > Driver tab.
  •  If the problem started recently, click Roll Back Driver:- 
  •    If the driver is old or corrupt, click Update Driver and search for updates.
  •    Restart your PC normally.
3. Hardware malfunction :- 
  • Test the Monitor with Another Computer:  
  • Hook up your HP monitor to a different computer (such as a laptop or a friend’s desktop) using a different, reliable cable.  
  • If the monitor functions on the new computer, the issue likely lies with the video hardware or drivers of the original computer. You should then troubleshoot the original computer (for example, by updating or rolling back graphics drivers).  
  • If the monitor remains blank or problematic on the new computer, it's probably a hardware issue with the monitor itself.  
  • Test the Computer with a Different Screen:  
  • Connect your original computer to another working display (like a TV or another monitor) using a different, reliable cable.  
  • If the new display functions well, it suggests that the HP monitor is likely defective.
4. Wrong refresh rate or resolution

The main solution is to adjust the monitor to its native resolution and the maximum refresh rate that both the monitor and your connection cable support.

1.Reset Monitor to Default Settings
Start with these simple steps:  
Restart your computer.  
Press the Auto button on the monitor (if available) to activate the Auto Adjustment feature.  
Use the On-Screen Display (OSD) menu buttons on the monitor to choose Factory Reset or Default settings.

2. Set Native Resolution (Recommended) 
LCD monitors provide the best image quality when operating at their native resolution (the actual number of physical pixels).  
You can find the native resolution in the monitor's manual or on the HP product specifications page.  
To change the resolution in Windows:  
Right-click on the desktop and choose Display settings.  
Under Display resolution, select your monitor's recommended or native resolution.  

3. Adjust the Refresh Rate
You need to set the refresh rate in your operating system, and it might also need to be configured in your GPU control panel (NVIDIA, AMD, or Intel).  
To change it:  
Right-click on the desktop and select Display settings.  
Scroll down and click on Advanced display (for Windows 11) or Advanced display settings (for Windows 10).  
Choose your HP monitor from the dropdown menu.  
Under Choose a refresh rate, select the maximum Hz available (e.g., 60Hz, 75Hz, 144Hz).  
If you can't select your preferred rate: Click Display adapter properties (or Display adapter properties for Display [number]), go to the Monitor tab, and pick the rate from the Screen refresh rate dropdown menu.
