Zorluk: ZorVideo, Display, and Projector Issues

A CAD workstation user reports that visual artifacts—such as random geometric shapes, flickering color dots, and line tearing—appear across both screens only when performing heavy 3D rendering operations. When the system is idle or performing basic desktop operations, the display image is completely stable and crisp. The technician has already replaced the DisplayPort video cables and verified that the monitor refresh rates match the manufacturer specifications. Which of the following is the MOST likely cause of this issue?

  1. Overheating GPU memory or failing onboard Video RAM (VRAM)Cevap
  2. B
    Corrupted monitor device driver software within the operating system
  3. C
    Insufficient video cable bandwidth capacity for high-resolution 3D graphics
  4. D
    A failing backlight inverter board inside the primary LCD monitor panel

Cevap

Overheating GPU memory or failing onboard Video RAM (VRAM) is the most likely cause of rendering artifacts under 3D workload.
Visual artifacts such as flickering dots, checkerboard patterns, or stray geometric lines that manifest only during intensive 3D rendering tasks indicate hardware degradation or overheating of the graphics processing unit's onboard memory (VRAM). When VRAM overheats or fails to maintain clock stability under heavy load, corrupt data is written to the frame buffer, resulting in visible screen distortion.

Adım Adım Çözüm

1
Analyze reported visual symptoms and triggering conditions.
Geometric distortion, flickering dots, and artifacts appear specifically during 3D workload stress, but disappear at idle.
Hardware components dedicated to 3D buffer processing (GPU/VRAM) operate under increased thermal and voltage loads during 3D execution.
2
Evaluate already attempted troubleshooting steps.
Replacing cables and verifying refresh rates did not resolve the problem.
Eliminates external transmission medium failure and display timing mismatches.
3
Isolate the root cause component.
Identify VRAM thermal failure or memory module degradation on the graphics expansion card as the primary cause.
Corrupted or overheating VRAM directly causes frame buffer corruption, manifesting as rendering artifacts.
