Multiscreen Users: Send new GT 730 and RX 500-series graphic cards to support up to 6-way HDMI output

News from IT House 5 June, according to Wccftech today, Biostar launched its special graphic card for multiscreen users at the 2026 Taipei International Computer Fair and displayed a new Z890 Valkyrie-S masterboard.

In the case of graphic cards, three products have been launched for multiple monitor users. The first is based on the NVIDIA GeForce GT 730 model, which uses a single-cell design and passive dissipation programme with a 4GB GDDR3 display, with a 64-bit display and four HDMI interfaces that can be operated without external power supply.

The second product is Radeon RX 550-4HDMI. As its name, the card is equipped with four HDMI interfaces to carry the 4GB GDDR5 display, using a 128-bit storage width. The product is also designed for single slot specifications, but is equipped with single fan heaters and does not need external power supply.

The third is Radeon RX 580-6HDMI, equipped with 8GB GDDR5 visible and 256-digital sizes, with six HDMI interfaces. The product is designed to be Mini-ITX-sized, equipped with a single fan double-train heater and provided with single 6pin power.

In the main panel, Z890 Valkyrie-S was displayed as an upgraded version of Z890 Valkyrie, which was introduced earlier, using the ATX panel and coated in full gold.

IT House noted that the main board used a double 8pin power supply, which provided 4 DDR5 memory slots with a maximum of 256 GB capacity and integrated power and restart keys on the plate.

In terms of extension, the main plate consists of three PCIe x 16 slots, which contain at least one Gen5 x 16; six M.2 slots, which cover all dispersible armour, and the Gen5 M.2 slots, which have deremovable designs; and four SATA 3 interfaces, with DEBUG LED at the bottom.

Backup I/O provides USB4, Wi-Fi 7, Bluetooth 5.4, multiple USB Type-A, double HDMI plus a DP interface, as well as 5G and 2.5G double gateways, and a dedicated USB interface for updating BIOS.

The main plate covers large areas of aluminium dispersors, and Valkyrie panels on I/O armour support LED lights. The price of Z890 Valkyrie-S has not yet been confirmed and is expected to be high.
