Time delivery to start ;-) No retreat on the reliability of the product but it works perfectly for the intended use ie log (first connection without any problem) a VGA external display (1280x1024) on my laptop Dell Inspiron 17 (1920x1080) which has only an HDMI output. Windows 8.1 recognizes the resolution VGA screen and allows both simultaneous display on both screens (restriction of the resolution of the notebook screen) as the extension on second display via the option: Peripherals-> Projeter- > Extend windows 8.1. For information, I also tested without success, use a case with Netgear PTV3000 (Push2TV) but it does not work: no image obtained on the VGA monitor while it works when I connect the Netgear box on my TV via an HDMI cord. This seems consistent with the transmission of the resolution of the monitor to the PC: There should not be any transformation of the image depending on the screen resolution but only converting HDMI to VGA signal. In short, very satisfied with my purchase.
