How to Fix No Signal Issues on Portable Monitors
You have just opened your sleepy new compact monitor, which is going to turn your laptop into a dual-screen beast or provide your Steam Deck with a bigger screen. You turn it all in, turn it on, and nothing. Nothing but a blank, black screen with the ghastly No Signal flashing across it. It is a frustrating experience that turns an exciting experience into a nightmare of problem-solving. But don’t worry. This problem is pervasive, and in the majority of situations, it can be solved with ease. The following guide will take you through a systematic approach to diagnosing and fixing the issue of No Signal to ensure that you are back to work or play within minutes.
Step 1: The First-Aid Checklist
We shall first run our errands in simple settings. In more cases than not, the answer is often very easy.
Check All Physical Connections: The most common criminal. Ensure that you possess a cable with one side firmly fixed to the monitor and the other to the device you are utilizing as a source (laptop, console, etc.). Connection should also be checked in the case of an adapter or dongle. Ensure that the plugs are well installed by pushing them in.
Power Cycle everything: Turn off your portable monitor and your source too. Take the portable monitor out of power. Wait for about 30 seconds. Next, re-plug the monitor, make certain it is turned of,f and then turn on your source device. A large number of temporary glitches can be solved simply by resetting the machine.
Check your device status
Verify the Source is Awake: Does your laptop have a sleeping mode? Are the video output settings of your console adjusted? On a computer, press the Windows key + P and choose to duplicate or extend to make sure it is attempting to send a signal to an external screen.
Step 2: Navigating the Software Maze
In the event that the physical checks fail, there is probably a problem with the software settings of either the monitor or the source device.
Select the Correct Input Source: Most portable monitors include a range of inputs (e.g., HDMI and USB-C). They are typically cycled with a physical button or on a menu shown on the screen. Make sure that the monitor is connected to the input port that you are dealing with. To use as a case study, when you are connected using USB-C, you must change the input of the monitor to USB-C or DisplayPort and not HDMI.
Adjust Display Settings on Your Source Device: Right-click on the Desktop and then click Display Settings, and on a Windows laptop, right-click the Display Settings again. Ensure that the external monitor is identified. If not, click “Detect.” On the Mac, this is found in System Settings, Displays. In the case of console devices, such as the PS5 or Switch, you should make sure that you have a supported cable and that the video output of the device is set to an acceptable resolution and refresh rate by the monitor.
Enhance your visuals
Update Graphics Drivers: Corrupted or old graphics drivers are also one of the leading causes of display errors in the case of laptops. Visit the webpage of the manufacturer of your graphics card (NVIDIA, AMD, or Intel) and download the latest drivers.
Step 3: Hardware and Compatibility Deep Dive
In cases where software and mere connections are not the issue, one should consider the hardware itself.
Cable Quality and Type: Cables are not all equal. An inexpensive and uncertified cable might not be capable of supporting the bandwidth of a higher resolution or refresh rate. In case you are attempting video transmission.
Power Delivery Problems: Several portable monitors for laptops to display a 4K 60Hz signal, make sure to use a High-Speed HDMI cable. With USB-C connections, ensure that the cable and the port on your laptop have DisplayPort Alt Mode, which is needed to be able to draw power and video on a single USB-C port. There are, however, laptops that might not offer sufficient power over that port. In case your monitor has a separate power input, it can be advised to plug it into a special wall adapter. This may frequently help with a No Signal problem due to a power deficiency.
Product Spotlight: How Different Models Behave
Sometimes, the issue can be specific to the model you own. Understanding these nuances can help. For instance, a popular Uperfect Portable monitor might have particular requirements for its USB-C connection to function correctly.
Let’s look at a few examples:
UPERFECT Models

3. ASUS ROG Strix XG17AHP
Power: This monitor includes a built-in battery, which changes the power dynamic.
Power Status: A “No Signal” issue could be related to the battery being completely depleted or a faulty charging cable, so it’s essential to verify its power status first

4. View Sonic TD1655
Drivers: While primarily a productivity monitor, it may require specific drivers for full touchscreen functionality on Windows.
Compatibility: A driver issue is less likely to cause a “No Signal” error, but installing official drivers from ViewSonic can resolve other display anomalies.
The Final Test: Isolation
When all the other things have been tried, then it is time to isolate the problem. Connect your portable laptop monitor to another device, such as another laptop or a game console. In case it works, then the problem lies with your primary source. In case it still displays No Signal, then the monitor (or its cable/power adapter, which is included with it) is probably defective and may require replacement. Through these steps, you can go step by step through the issue and transform that blank screen into the bright and productive thing you were seeking.
