While Sceptre has a strong lineup of budget friendly monitors, they do come with a few challenges. One such challenge reported by many users working from home is encountering the Sceptre monitor no signal error. Here’s how to fix it.
Sceptre Monitor No Signal
To fix the Sceptre monitor no signal issue, turn off and unplug the monitor and your computer. After 30 seconds, power on the monitor first, followed by your computer. If the issue persists, ensure the correct input and display resolution settings are selected and all cables are secure and undamaged.
There are 7 common troubleshooting steps you should try.
Some of these fixes involve troubleshooting the display directly, while others involve troubleshooting your PC.
I strongly recommend you follow these steps in order.
We will start with the most common fixes and then work our way towards less common, more involved troubleshooting steps.
Troubleshooting The Display
Step 1: Unplug And Reboot The Monitor And PC
Before trying anything else, turn OFF and unplug your monitor and your computer. After 30 seconds plug everything back in and turn ON the monitor FIRST, followed by the computer SECOND.
I know, I know. You didn’t come here to be asked “Did you try turning it off and turning it back on again?”
Humor me. The sequence is IMPORTANT – so again, turn on the monitor FIRST, then computer SECOND.
Countless Sceptre monitor users have indicated that after trying everything else, this simple solution worked for them.
So you’ve tried unplugging and rebooting the devices and still, you’re encountering the problem?
No need to worry just yet – advance to step 2.
Step 2: Adjust The Monitor Input Setting
It is important to make sure your monitor is set to the correct Input.
To do this, you need to first know what kind of input cable you are using.
Sceptre monitors most commonly support 4 different kinds of cables: HDMI, DisplayPort (DP), DVI and VGA. Identify which cord you have using the image below.
Once you have identified the cable you are currently using, locate the Source or Input button.
The Source/ Input button will either be located in the middle or right-hand side of your monitor. It will either be on the backside of the display or towards the bottom.
For some models, you will first need to use the Menu button and then navigate to Input.
Once you press the Input and/or Menu button, options will appear on your monitor. Toggle the input options until you identify the input that matches your input cable.
Step 3: Inspect The Display Cables
Now that we are sure your monitor is set to the correct Input, let’s check your display cable connections.
First and foremost, make sure that the connection is firm on both ends.
A loose cable can cause a whole host of issues, from screen flickering, no signal errors, and more.
Even a slightly broken connection can cause an error.
That tiny space you see in the image below between the HDMI and the HDMI port in my laptop?
You guessed it – that was enough to trigger the problem.
Next, make sure there are no issues or obstructions with the cable itself. Check for any signs of visible damage.
Finally, try using a different input cable than you are currently using.
If you are specifically using HDMI, try swapping it out for a DP, DVI or VGA cable and vice versa.
When you try a new cable, be sure to follow the process in step 1 again and adjust the display Input accordingly.
If using a different display cable solves the issue, a faulty display cable was likely the culprit.
Step 4: Adjust The Monitor Resolution Settings
Your Sceptre monitor has a range of possible display resolutions that it can relay back to your PC.
It is possible that your computer’s graphic card is currently set on a display resolution that is higher than what your monitor can handle.
This can sometimes even lead to your monitor not turning on all together. The easiest way to fix this is to hook your PC up to a different monitor and then adjust your resolution settings to the lowest level.
Navigate to Settings > Display and scroll down to Display resolution.
Alternatively, if you do not have a second monitor to use, try rebooting your computer using Safe Mode.
In Safe Mode your computer will automatically use a lower display resolution than normal use.
This will allow you the opportunity to go into your computer’s resolution settings and select a lower standard display resolution.
Not sure what resolution your monitor can support? You have two options:
- Find your model number on the back of your monitor and locate it in the Sceptre monitor user manual lookup.
- Play around using some trial-and-error. Incrementally increase your resolution. Wait approximately 30 seconds between each update and see whether the error message pops up.
Troubleshooting Your PC
We are now at the end of the most common fixes if your monitor is the source of the problem.
To confirm that your monitor is the issue, try using your monitor with another device.
This can be another laptop, desktop computer, game console, etc. If your monitor display works, then you know your monitor is working properly and your computer/ hardware is the culprit.
First, a few disclaimers. Steps 6 and 7 below require you to open and manipulate your laptop or desktop computer.
If your hardware is company property, it is best to leave these steps to your company’s IT support.
If your computer/ hardware is personally owned, you can also consider bringinging it in to a local computer repair shop.
However, if you do plan to proceed make sure you have done proper research. At a minimum you should know how to properly ground yourself to avoid destroying your computer with electrostatic charge.
Step 5: Ensure The Display Cable Is Plugged Into Graphic Card And Not The Motherboard
Nearly all desktop PC’s have an on-board graphics unit with corresponding connections on the back of your computer.
If this applies to you, be sure that your monitor cable is connected directly into the graphic card and NOT the motherboard.
Often times with a desktop PC it can be as simple as that.
Step 6: Remove, Reorder, and Reseat The RAM Sticks
It is also possible your RAM (Random Access Memory) sticks are not making a proper connection.
To fix this, first power the computer off and remove the power cord from the outlet.
Next, properly ground yourself, open your PC unit and fully remove each of your RAM sticks.
Lastly, reorder the sicks and reinsert them back into their respective RAM seats.
Step 7: Reset CMOS/BIOS
CMOS stands for Complementary Metal Oxide Semiconductor.
The CMOS battery in your laptop or computer powers the BIOS firmware. BIOS stands for “Basic Input/Output System” and it manages the essential functions of your computer.
Resetting your BIOS sets it back to its previous configurations and can often fix a lot of different issues.
Once again make sure your computer is powered off, the power cord is removed, and you are properly grounded.
Next, remove the CMOS battery from the motherboard. Then, hold down the power button to drain all excess remaining power.
After about a minute, reinsert the CMOS battery back into your PC.
Finally, Reboot your computer and check to see if your display is working.
To fix the Sceptre monitor no signal problem, follow these 7 troubleshooting steps and get your dispay back up and running in no time:
- Unplug and reboot monitor and PC
- Adjust monitor to the correct input
- Inspect display cables
- Check monitor resolution settings
- Ensure input cable is plugged into graphic card
- Remove, reorder, and reinsert RAM sticks
- Reset CMOS/BIOS
