[Material advantages] Use high quality gold-plated connectors, support DP 1.2 stable transfer. PCB uses high-quality low-resistance high-quality materials, PCB workmanship precision, PCB uses high TG sheet, copper thickness is thickened to 1oz; connector gold-plated conductive performance, can reduce the black screen blue screen splash caused by increased oxidation rust resistance Flower screen problem.[Design advantages] differential signal without via design, no CAF -type short circuit phenomenon, high speed signal data transmission without parasitic capacitance and parasitic inductance signal attenuation interference problem, circuit enhanced wiring design, PCB board miniaturization design, can reduce mechanism interference , no card hardware, product installation is easy.[Is there any EMI shielding for Cable] The extender utilizes the latest materials for EMI shielding with five sole flat cables design.[Cable length ] The length of the wire refers to the part of the visible wire. It does not include the PCB and the connector.Note: The extension cable does not support two or more DP cables connected in series. If you connect more than two DP cables in series, the signal will be attenuated. It may not be used normally.Product specification:Product name: DP Male to DP Female CableProduct model: P3-P4Transfer speed: support of increased bandwidth up to 32.4Gbps, HDR/DSC resolutions up to 4K @ 60 Hz,Application: For Video card, Graphics card extension,support DP1.2 version, support (HDR/DSC) high dynamic range video transmission, 32.4Gbps bandwidth, resolution 4K(UHD)/60p,Refresh rate: 1080P-240Hz, 2K-144/165Hz, 4K-60HzSound transmission: 32 bit /1536kHzColour:BlackMaterial:PCB+TPESize:Cord length: about 30cmPackage Contents:1 * Display Port Extension CableOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
