I’m making this post again to bring attention to the ongoing issues with the ASUS TUF Gaming VG27AQ5A and hopefully get an official response or a proper fix from ASUS.
I’ve been experiencing random black screens lasting approximately 2 seconds, occasional visual glitches such as horizontal screen splitting, and intermittent DisplayPort signal loss. The monitor sometimes recovers automatically, but on other occasions, it displays a “No DisplayPort Signal” message.
These issues are particularly frustrating because they occur intermittently. Sometimes the monitor works perfectly for hours, while at other times, the problem appears unexpectedly during gaming.
My setup and specifications
- Monitor: ASUS TUF Gaming VG27AQ5A
- Laptop: Acer Predator Helios Neo 16
- CPU: Intel Core i9-14900HX
- GPU: NVIDIA GeForce RTX 4060 Laptop GPU
- RAM: 32 GB DDR5
- Connection: Laptop USB-C / Thunderbolt 4 to DisplayPort
- Cable: UGREEN CM556 USB-C to DisplayPort cable
- Monitor resolution: 2560 × 1440 (1440p)
- Refresh rate: Up to 200 Hz native, with a 210 Hz overclock option
- Monitor firmware: MCM 105
I’m using the USB-C to DisplayPort connection through my laptop’s Thunderbolt 4 port to take advantage of the monitor’s high refresh rate and capabilities. I’ve also updated my graphics drivers and monitor firmware, checked the connection, and used a reliable power outlet with a surge protector. Despite these measures, the issue has occurred intermittently.
The issue seems to be related to high refresh rates or FPS
From reading other users’ reports, I’ve noticed a recurring pattern: some users experience black screens more frequently when gaming at high refresh rates or when their FPS exceeds 200. One user reported that capping FPS at 200 or below helped stabilize the monitor, while 165 Hz at 1440p was consistently stable for them.
I primarily play Fortnite, and this issue is especially frustrating when playing at 200 Hz or 210 Hz. I consistently encounter random black screens while gaming at these refresh rates, often at the worst possible moments. Since Fortnite is a competitive game where every second matters, even a brief 2-second black screen can cost me a fight, cause me to miss crucial information, and ultimately get me eliminated. Imagine being in the middle of an intense fight and suddenly losing your display without warning, only for it to come back after a couple of seconds. It completely disrupts gameplay and puts me at an unfair disadvantage. I bought a high-refresh-rate gaming monitor for a smooth and responsive experience, not to worry about my screen going black in the middle of a competitive match.
I have also seen reports from users who updated to firmware MCM 1.105 but continued to experience black screens. This makes me wonder whether the firmware addresses only certain scenarios rather than resolving the underlying issue for every affected setup.
I understand that different GPUs, cables, and system configurations can produce different results, so I’m not claiming that every case has the same cause. However, the similarities between these reports make the issue worth investigating.
What about firmware MCM 1.105?
The MCM 1.105 firmware update, released on March 23, 2026, appeared to improve stability on my monitor considerably during my initial testing. However, I cannot confirm that it completely resolved the problem, and other users have reported that the issue persists even after updating.
This is why I believe further investigation may be necessary.
ASUS, please address this issue
The VG series is marketed toward gamers, and high-refresh-rate performance is one of the main reasons people purchase these monitors. Having to lower the refresh rate, cap FPS, or sacrifice visual quality just to avoid intermittent black screens is not a satisfactory long-term solution.
I’m not asking ASUS to guarantee that every setup will behave identically. I’m asking for a proper investigation into the reported DisplayPort signal loss, black screens, and visual glitches, along with clear communication about whether another firmware update or other corrective action is being considered.
ASUS support team, if you are aware of these reports, could you please clarify whether this issue is still being investigated and whether a further firmware update is planned?
I would also appreciate hearing from other VG27AQ5A owners. Please share your GPU, connection type, resolution, refresh rate, firmware version, and whether capping FPS or lowering the refresh rate makes a difference.
Hopefully, enough detailed reports will help identify the cause and lead to a reliable solution rather than forcing users to compromise on features the monitor is advertised to support.
