The OverDMA DC505 is our flagship 4K dual-PC video fuser, combining ultra-high-refresh HDMI 2.1 and DisplayPort fusion with an integrated capture card and custom EDID support.

It merges the video output from your gaming PC and DMA PC into one seamless native-resolution image on your primary monitor, with extremely low and consistent latency.

Up to 550Hz

1920×1080 up to 550Hz · 2560×1440 up to 360Hz · 3840×2160 up to 160Hz

Backward compatible with lower refresh rates.

Note: peak figures require an AMD RX 6000-Series or NVIDIA RTX 50-Series GPU. NVIDIA RTX 30 and RTX 40-Series GPUs are generally limited to 1080p 480Hz, 1440p 320Hz and 4K 144Hz due to DSC behavior. Some RTX 5070 Ti or higher GPUs and newer laptops may require the selectable 12G HDMI link mode.

⚠️ Important: don't mix connectors

HDMI and DisplayPort cannot be mixed. Your gaming PC, DMA PC and monitor must all use HDMI, or all use DisplayPort.
