Product story

Details worth knowing

Dtech DT-CU0308 3 m DisplayPort Cable Connect a DisplayPort-equipped computer, graphics card or other compatible source to a DisplayPort monitor with the Dtech DT-CU0308. The cable has DisplayPort connectors at both ends and a listed length of 3 metres, giving more reach than a short desk cable. Check the connector ports on both devices before ordering; this is DP-to-DP, not DisplayPort-to-HDMI, Mini DisplayPort or USB-C. Resolution and version Star Tech lists DisplayPort 1.2 and support for resolutions up to 3840 × 2160 (4K). This is the cable's listed maximum resolution, not a guarantee that every setup will run at 4K or a specific refresh rate. Actual resolution, refresh rate, colour depth and audio support depend on the source device, monitor, graphics hardware, settings and the complete connection. The listing does not specify a refresh-rate figure, so confirm the exact mode needed for your display before purchase. Length and construction The cable is 3 m long. Star Tech lists an outer diameter of 7.3 mm. The ends are described by retailers as DisplayPort male connectors, with latches reported on the plugs for a more secure connection; press the release mechanism before unplugging if your cable version has latch tabs. Avoid pulling the cable itself and check the connector shape against your ports. The cable listing describes transmission of video and audio over DisplayPort; audio output still depends on source and display support and configuration. Specifications Brand: Dtech (shown as DTECH by Star Tech) Model: DT-CU0308 Cable type: DisplayPort to DisplayPort Connectors: DP male to DP male Length: 3 m DisplayPort version listed: DP 1.2 Maximum listed resolution: up to 3840 × 2160 (4K) Outer diameter listed: 7.3 mm Colour: Black (Ryans listing) Warranty: Star Tech lists no warranty; other retailers may provide different terms Before buying Confirm that both the source and display have a compatible full-size DisplayPort connection and that the cable length suits the route without tension. Verify your target resolution and refresh rate against both devices, since the retailer's listing gives a 4K maximum but no refresh-rate detail. Check the seller's current stock, return policy and written warranty. Star Tech lists ৳690 (regular ৳705), TechLand and CSI list around ৳690–700, while other shops show different prices; offers may change. The visible price range is a comparison estimate and not a live store offer.

Helpful answers

Frequently asked questions

Product-specific answers maintained with the catalog information.

What devices does the Dtech DT-CU0308 connect?

What is the cable length and DisplayPort version?

The DT-CU0308 is listed as a 3 m DisplayPort 1.2 cable. Confirm the route length you need and leave enough slack to avoid strain on the plugs.

Can it support a 4K display?

Star Tech lists support up to 3840 × 2160 (4K). The actual resolution, refresh rate and signal quality depend on the source, display and setup; the retailer does not specify a refresh-rate figure.

What warranty does Star Tech provide?
