Plugged in at first and thought it was great with my samsung TV neo TV (2024). As it seemed to work 120hz goodness etc - until i switched TV off and left ally in dock overnight expecting it to display on the neo again no joy - played around with settings on both ally x and samsung TV to see if it was that - no joy - borrowed a Jsaux 6 in 1 dock (upright new one) worked straight away so i will get one of these. If you are using for a ROG ally X and with a samsung neo - i cannot recommend. the work around is to switch off dock and then switch back on again and it springs back into life
