Maximum length of DisplayPort cable for optimal performance
When using display port cables, the length of the cable can greatly impact display quality and create data loss. While DisplayPort offers support for cables of varying lengths, the maximum cable length that Dell Technologies recommends for optimal performance is 1.8 meters (around 6 feet). Using a DisplayPort cable beyond 1.8 meters in length may cause data loss and a negative impact to display quality.
