If you are experiencing the “screen suddenly goes black” symptoms, possible causes include a graphics driver crash or display output change. First check if Windows is running, then check the output mode and graphics driver in that order.
PC turns on but there is no display
If the PC powers on but there is no display, first check the monitor input and cable, then the graphics card and RAM POST status. Check the display output path one step at a time.
Problem with No Signal appearing on the monitor
If “no monitor signal” occurs repeatedly, it is better to narrow it down to a faulty input source, bad cable or port, rather than changing several settings at once. Cross-testing the input source, cables, ports, and then other monitors can help isolate output device and PC issues.
The monitor is turned on but the screen is black.
When troubleshooting a monitor that is turned on but the screen is black, it is important to rule out causes one at a time. Based on the “monitor is powered on but black screen” symptom, check for problems with the input signal, brightness, or panel, then proceed to the next step. Cross-testing the input source, cables, ports, and then other monitors can help isolate output device and PC issues.
Issue where only the mouse cursor is visible on the Windows black screen
If “only black screen cursor” occurs repeatedly, it is better to narrow the issue to Explorer or Windows process freezing or graphics driver issues rather than changing several settings at once. First check if Windows is running, then check the output mode and graphics driver in that order.
Black screen after logging into Windows
When troubleshooting a black screen after logging into Windows, it is important to rule out the causes one at a time. Based on the “black screen when logging in” symptom, check the user profile, Explorer issue, or display output settings and proceed to the next step. First check if Windows is running, then check the output mode and graphics driver in that order.
Black screen after Windows update
If the “black screen after update” occurs repeatedly, it is better to narrow it down to incompatible display drivers, incomplete updates, or conflicts rather than changing several settings at once. First check if Windows is running, then check the output mode and graphics driver in that order.
Screen flickers or flashes repeatedly
When troubleshooting a screen that keeps flickering or flashing, it is important to rule out the causes one at a time. Based on the “screen flickering” symptom, check for graphics driver, refresh rate, or cable issues before proceeding to the next step. Resolution, refresh rate, HDR, VRR and cable bandwidth must be checked together to distinguish between setup issues and hardware limitations.
Screen tearing issue in games or videos
If “screen tearing” repeats, it is better to narrow the scope to frame and refresh rate synchronization issues and V-Sync/VRR setting issues rather than changing several settings at once. Resolution, refresh rate, HDR, VRR and cable bandwidth must be checked together to distinguish between setup issues and hardware limitations.
The screen freezes and the mouse or keyboard does not respond.
If you are experiencing “freeze” symptoms, possible causes include driver or memory errors, storage device lag, etc. Record the conditions under which the symptom occurs and any recent changes, and then check for software and hardware causes.
Issue where desired screen resolution is not selected
If you see the “Resolution not selected” symptom, possible causes include not installing graphics drivers, cable/adapter restrictions, etc. Resolution, refresh rate, HDR, VRR and cable bandwidth must be checked together to distinguish between setup issues and hardware limitations.
Problem with monitor 120Hz, 144Hz, 165Hz not being selected
If you see the “No 144hz” symptom, candidate causes include cable bandwidth limitations, resolution/refresh rate combination limitations, etc. Resolution, refresh rate, HDR, VRR and cable bandwidth must be checked together to distinguish between setup issues and hardware limitations.
Second monitor not recognized in dual monitors
If the symptom of “one side of the dual monitor is not working” appears, possible causes include cable/port problems, display mode settings, etc. Resolution, refresh rate, HDR, VRR and cable bandwidth must be checked together to distinguish between setup issues and hardware limitations.
Monitor has no display after waking from sleep
When troubleshooting the problem of the monitor not displaying after waking up from sleep mode, it is important to rule out the causes one at a time. Based on the “no screen after power saving” symptom, check the graphics driver power management and monitor handshake before proceeding to the next step. Check at which stage it fails during sleep entry and exit, and check the driver, power policy, and BIOS in that order.
Problem with no screen when connected via HDMI
If you are seeing the “No HDMI” symptom, potential causes include input source or cable issues, or port damage. Cross-testing the input source, cables, ports, and then other monitors can help isolate output device and PC issues.
Problem with no screen on DisplayPort connection
Among screen problems, the “No DP” symptom may be related to cable/port/input source problems or monitor power saving handshake. Cross-testing the input source, cables, ports, and then other monitors can help isolate output device and PC issues.
