A:Answer V-series isn't being marketed. It's an off-shoot of the D-Series except it has Dolby Vision HDR. It only has 1 usb port however, and D and E series usually have two.
E-series contains brighter HDR visual contrast, but V-Series although utilizing Dolby Vision HDR is pretty similar to D-Series peak brightness, which isn't that great for HDR anyway.
E-series also contains an adaptive full array panel, which means it can dynamically adjust the brightness of certain parts of the screen depending on content, for a deeper contrast and thus deeper blacks and brighter whites. D-Series and V-Series just have full array LED, which works nicely, but it won't achieve the same level of contrast.
