When an MSI PC throws a DisplayPort error or fails to output an image, it usually means the hardware handshake between your graphics card and monitor broke down. You power on your rig, the fans spin, but the screen stays black or flashes a warning message. This happens because the GPU and monitor can't agree on signal timing, bandwidth, or protocol standards.
Fixing this requires isolating whether the fault lies in your cable, UEFI settings, or physical GPU seating. Let's walk through how to get your display working properly without guesswork.
Inspecting Physical Connections and Hardware Integrity
Most display output failures start with simple physical mismatches or loose ports. Don't assume a cable works just because it's plugged in tightly.
- Check both ends of your DisplayPort cable. Push firmly until you feel a distinct click, ensuring the locking pins engage if your cable has them.
- Inspect the pins inside the connector. Bent pins or dust accumulation inside the GPU port can disrupt the hot-plug detect (HPD) line.
- Disconnect any cheap HDMI-to-DisplayPort adapters or unpowered splitters you're using. These adapters often drop handshake signals entirely.
- Plug your monitor into a different port on your graphics card to see if one specific output failed.
If your cable is rated only for DisplayPort 1.1 or 1.2 and you're trying to push a 4K 144Hz signal from an RTX or Radeon card, the monitor may reject the handshake completely. Swap to a VESA-certified DisplayPort Cable Specification standard cable rated for HBR3 or DP80 speeds. Further reporting on this trend has been provided by BBC.
Resetting and Configuring UEFI/BIOS Settings
Sometimes your MSI motherboard's UEFI configuration interferes with how PCIe graphics lanes initialize during boot. If your motherboard's BIOS version is outdated, it might mishandle newer graphics cards.
- Power down your PC completely and unplug the power supply cable.
- Clear the CMOS by bridging the JBAT1 jumper pins on your MSI motherboard for ten seconds, or remove the coin-cell battery for one minute. This resets corrupted display configurations.
- Boot into the BIOS by tapping the Delete key repeatedly during startup.
- Navigate to the Settings menu, select Advanced, and look for PCIe Subsystem Settings or Integrated Graphics Configuration.
- Set the primary video adapter explicitly to PEG (PCI Express Graphics) rather than IGD (Integrated Graphics) if you're using a dedicated GPU.
- Disable CSM (Compatibility Support Module) if your GPU fully supports UEFI GOP (Graphics Output Protocol), which resolves handshake conflicts with modern monitors.
If your motherboard runs an outdated firmware version known to cause handshake bugs, visit the official MSI Support Center to download and flash the latest stable BIOS update using a FAT32-formatted USB drive.
Resolving GPU Power and Seating Issues
A graphics card that sags slightly in its PCIe slot can lose contact with specific data lanes, causing display output failure while still supplying enough power to spin fans.
- Power off the system, flip the PSU switch, and discharge residual power by holding the PC power button for five seconds.
- Release the PCIe slot retention clip and pull your graphics card straight out.
- Clean the gold PCIe edge connector gently with a clean microfiber cloth.
- Reseat the card firmly until the retention clip clicks back into place.
- Ensure all PCIe power cables from your power supply unit are clicked securely into the GPU headers. A loose 8-pin or 12VHPWR connector can starve the video output controller.
If you're using a vertical GPU mount with a riser cable, remove the riser and plug the graphics card directly into the top motherboard slot. Many budget riser cables fail to support high-speed DisplayPort signaling protocols, resulting in constant black screens.
Frequently Asked Questions
Why does my monitor say "DisplayPort Incorrect" only when Windows loads?
This happens when your graphics card driver attempts to output a resolution or refresh rate that exceeds your cable's bandwidth capacity or your monitor's supported timing table. Boot into Windows Safe Mode by interrupting the boot process three times, uninstall your GPU drivers using Display Driver Uninstaller (DDU), and install fresh drivers from the official NVIDIA Drivers or AMD website.
Can an outdated monitor firmware cause this error?
Yes. Many high-refresh-rate gaming monitors have internal firmware bugs that fail to handle deep sleep states or display port handshakes correctly. Check your monitor manufacturer's support page to see if a firmware update tool is available via USB.
How do I fix the black screen if I cannot see the BIOS?
If you can't see the BIOS screen to change settings, unplug all secondary monitors, test a standard HDMI cable instead of DisplayPort just for troubleshooting, or plug your monitor directly into the motherboard's integrated graphics port if your CPU has an internal GPU. Once you reach the desktop or BIOS, you can adjust your display priorities.
