Zorluk: Çok zorVideo, Display, and Projector Issues

A desktop workstation dedicated to 3D computer-aided design (CAD) rendering experiences severe visual artifacts—specifically random geometric spikes, checkerboard pattern corruption, and screen tearing—only when stress-testing or executing intensive 3D graphic workloads. When operating standard 2D productivity software, the display remains clear and completely stable. Which of the following hardware issues are the MOST likely causes of these symptoms? (Select TWO.)

  1. Overheating or failing video random-access memory (VRAM) chips on the dedicated graphics cardCevap
  2. Thermal degradation or instability of the main graphics processing unit (GPU) core under loadCevap
  3. C
    Corrupted monitor display drivers or invalid operating system color profile configurations
  4. D
    A failing backlight inverter board failing to supply consistent voltage to the LCD monitor

Cevap

The most likely root causes are overheating or failing video RAM (VRAM) on the graphics card and thermal degradation or instability within the GPU core under heavy 3D workloads.
Visual artifacts such as geometric distortion, checkerboard patterns, and texture glitches occurring specifically under 3D graphics loads indicate physical hardware failures on the dedicated graphics card. Overheating or damaged VRAM chips corrupt the frame buffer where texture data is stored. Simultaneously, severe GPU core overheating or hardware degradation causes mathematical calculation errors when processing 3D polygons.

Adım Adım Çözüm

1
Analyze the reported symptom and operational environment
Visual artifacts (geometric spikes, checkerboard patterns) occur strictly during 3D workload stress, while 2D rendering is completely clear.
Differentiating between 2D and 3D mode helps isolate physical GPU hardware stress from general display or OS issues.
2
Evaluate hardware components engaged during heavy 3D rendering
Heavy 3D rendering heavily stresses VRAM bus throughput and pushes the GPU core to peak operating temperatures.
VRAM bit errors lead directly to corrupted texture mapping and checkerboard artifacts, while GPU overheating causes processing math errors.
3
Eliminate non-hardware and peripheral failure modes
Display drivers and backlight inverters are ruled out because they do not selectively produce workload-dependent 3D visual artifacts.
Backlight issues affect illumination overall, and software drivers do not cause physical hardware memory corruption patterns.
