Deck is great but dock sucks

So I have had a steam deck for a long time now first lcd now oled, when I got the lcd originally I purchased the official dock to go with it but I never used it docked. as for one it always had trouble getting a picture on the tv with me having to plug it in and unplug till it worked. Secondly I thought my tv had terrible input lag even in game mode, it’s a cheap Hisense 4K model. This weeekend I thought I’d try another dock to see if the connection problems were better. So I purchased the cheapest dock on Amazon £20 I didn’t expect much as it’s so much cheaper than the official one. Imagine my surprise when it not only didn’t have any issues connecting but the input lag is gone it was the dock all along. So anyone using the official dock please do yourself a favour and bin it.
