A:Answer Thank you for reaching us regarding LG Monitor. When selecting between HDMI and DisplayPort for your LG 45GR95QE-B monitor, DisplayPort is often the better choice for top performance.
Key Differences:
• Bandwidth and Refresh Rates:
The LG 45GR95QE-B has HDMI 2.1 and DisplayPort 1.4 connections. While HDMI 2.1 can handle high refresh rates and resolutions, DisplayPort 1.4 provides more bandwidth, which is ideal for high refresh rates like 240Hz at 3440x1440 resolution. If your graphics card supports DisplayPort DSC (Display Stream Compression), you can achieve 240Hz with DisplayPort 1.4.
• Picture Quality:
Both HDMI and DisplayPort provide good picture quality when functioning properly. However, DisplayPort is typically better for higher refresh rates and resolutions, especially for gaming.
• Cable Quality:
Use high-quality cables to ensure optimal performance. An old HDMI cable might not support all features of HDMI 2.1, while DisplayPort cables should be at least version 1.2 or newer.
