I bought refurbished latitude 5175. I have the docking station of venue pro 11 which (K10A001). I found that latitude 5175 is compatible with venue pro 11 docking station, but when I put latitude 5175 on the docking station (K10A001), there is problem with the external display. It cannot detect display port while I use it as a connector from the dock to the display (however, USB connection and audio connection from the dock seems fine). When I put HDMI as connector from the dock to the external display, it seem the 5175 reject it, because the external display cannot detect while the 5175 screen become blink. When I put venue pro 11 in the same dock, it is working well. I already update Bios. Additionally, tried to update the dock driver but it failed. Please advice.
Try unplugging the usb connection and only plug in the HDMI. Also, try changing the display settings on the 5175 to a different setting.
