Totally. Yeah, I'd recommend dongles like you and I both posted, then. I will say that yours looks pretty solid in that it can rest flat when the deck is propped up. Both of mine kinda hang off the top of the deck and bend, but it's really more of a cosmetic thing that I'm fine with.
Also, the dongles are super slim and fit easily in the bottom of those smaller hard travel cases for the deck, even with a small charging block and normal sized cable.
Like another commentor said, it's definitely more important to check out the video/power supply specs and all that, but you can get a solid one for $20-$40 now, easily.
Edit: Plus, I have a couple of those right angle connectors that came with my case so if I really wanted to hide the cable a bit more, those would help. After trying out a couple different cases and dongle/dock combinations, it's amazing the amount of extra stuff these companies throw your way. I have more joystick caps and dongle peripherals than I know what to do with lol
