1-to-2 DisplayPort Splitter for Dual-Monitor Setups

The ESTONE OZFD takes a single DisplayPort 1.4 output and drives two DisplayPort displays at once. It suits professionals and gamers who need mirrored or extended desktops from one GPU port. A USB-C power cable and 5V/2A adapter are included to power the internal chip. The compact 74 x 74 x 14 mm black enclosure weighs 35 g.

DisplayPort 1.4 Bandwidth and Mode Limits

The splitter operates within the 32.4 Gbps bandwidth of the DisplayPort 1.4 standard. In MST extend mode the link tops out at 3840 x 2160 at 120 Hz, while mirror mode reaches 3840 x 2160 at 144 Hz on a single active output. Both connected monitors and the source GPU must support DisplayPort 1.4 and DSC to hit the highest figures. A 10 metre DisplayPort cable is the stated usage example.

4K Resolution Headroom and Practical Ceilings

One monitor can run 3840 x 2160 at 144 Hz when the other is idle or mirroring. With both screens active in extend mode the practical ceiling is 3840 x 2160 at 120 Hz on one and 60 Hz on the other. Pushing beyond these refresh rates or adding a third display is not supported. Buyers needing higher refresh rates or more than two outputs will need a different solution.

Questions about this item

Should I pick the mirror or extend configuration for two monitors?

Use mirror mode (A-A-A) when both screens must show the same 4K@144Hz image; use extend mode (MST) for independent desktops, which runs at 4K@120Hz on one output and 4K@60Hz on the other.

What does the 4K@144Hz rating mean when I plug in two displays?

A single active port delivers 3840×2160 at 144 Hz; with both ports active in extend mode the splitter drops to 4K@120Hz on one screen and 4K@60Hz on the other.

How does the DisplayPort 1.4 link limit what I can run?

The 32.4 Gbps bandwidth caps dual-stream operation at 4K@120Hz + 4K@60Hz, while a single stream can reach 4K@144Hz if the source, cable and monitors all support DSC.
