How these scores work

The Piqelo Score is our published assessment of this exact product, including value. Your search does not change it. The Search Score uses the underlying research, your preferences and comparison with similarly priced products. Value is counted once; budget and required features are hard limits.

Price comparison: $750.00 to $1,249.98 (±25% of this product’s price). Comparable evidence is limited.

Match evidence or required features still need confirmation.

Decision snapshot

Thunderbolt 5 ultrawide work

Best for: Large productivity desks needing 5K2K, Thunderbolt 5, KVM and 140W charging
