Dear Sir,

How about the DP139 MAX resolution?

Can support as below?

    Hello,

    It depends on the color depth, the DP130 supports data rates up to 3.4Gbps, for example, it supports 1920x1200@30fps with 12bit color depth, this is 36bpp which will give a raw data rate of about 2.48Gbps plus blanking periods.

    In addition, the DP130 is a TMDS single-link, so the pixel frequency at the HDMI output will be limited to 165MHz.

    Regards.

    Hi Sir,

    Sorry, we need provide the product SPEC. to end custom.
    DP139 can support resolutin under 165MHz, right?
    The mark "red" DP139 can support, right?
    DP139 can't support 1600*1200 (UXGA), right?

    Hello,

        what was mentioned by Elias is valid only for DVI, the SN75DP139 meets the HDMI 1.4b spec, supporting up to 3.4Gbps (340MHz max clock rate), which allows you to transmit a maximum resolution of 4K (4096 pixels wide by 2160 pixels high @ 24Hz).

    Best regards,

    Diego.
