SongryVGA SY586H42 Radeon RX 580 4GB GDDR5 6×HDMI 2.0 graphics card

Six-HDMI Multi-Display Card

The SongryVGA SY586H42 Radeon RX 580 delivers six HDMI 2.0 outputs from a single PCIe 3.0 x16 slot. It targets traders, signage operators and office users who need up to six 4K screens without adding extra GPUs. The 4 GB GDDR5 frame buffer and 256-bit bus feed the 2048 stream processors at 1244 MHz core and 1500 MHz memory clocks. DirectX 12 and OpenGL 4.6 cover modern desktop workloads on Windows 7 through 11.

Upgrade From Entry Multi-Monitor GPUs

Moving up from cards limited to four outputs or older HDMI 1.4 ports removes the need for splitters or daisy-chains. The jump is worth it when a single 6-pin connector and 80 W TDP fit the existing 450 W power budget while doubling usable display ports. The dual-slot, 6.85-inch form factor slides into compact chassis that cannot accept longer boards. No external adapters are required for native 4K60 on every port.

4 GB GDDR5 Headroom

Four gigabytes of GDDR5 handles desktop compositing, browser-heavy trading layouts and 4K video playback across six panels without paging. The 256-bit interface sustains 1500 MHz effective bandwidth for smooth window drags and scrolling. Memory pressure appears when driving multiple 4K gaming or 3D rendering contexts simultaneously; compute workloads exceeding the 4 GB limit will spill to system RAM. For pure 2D productivity and signage loops the buffer remains comfortable.
