When sourcing Wall TV Stands, the most critical factor is the VESA Pattern Compatibility (e.g., 200x200, 400x400, 600x400mm), which ensures the mount matches the hole configuration on the back of the TV. Additionally, you must verify the Weight Capacity, ensuring the stand can support at least 1.5 times the weight of the intended display for a safety margin. Material quality is paramount; prioritize Cold-Rolled Steel (SPCC) with a thickness of at least 1.5mm to 2.0mm to prevent sagging or structural failure over time.
