An open TV stand looks light right up until you plug something in. With no cabinet to swallow the cords, every cable is on show. The good news: you do not really hide cables on an open stand. You tidy them. A tidy open stand looks better than a closed one with a rat's nest behind the doors.
One deliberate line down the back. Not invisibility. Intention.
The screen hangs from the VESA brackets. The cables start at the back of the set and need a short, obvious path to the floor and the wall. That is the whole problem.
First, own fewer cables
The easiest cable to hide is the one you do not have. Cut the count before you route anything. A modern TV needs power and, ideally, a single source. A streaming stick in the back of the screen replaces a box, its power lead, and an HDMI cable. A soundbar adds one cable. Consoles: only the ones you actually use, left plugged in. Most cluttered setups are two devices too many.
Then run everything down one side
Stop the cables spreading. Bundle them and bring them down one back leg, or one back corner, so the eye sees one vertical line rather than a web. A few clips, a fabric sleeve, or a spiral wrap turns five cords into one. Stick the clips on the inside of the leg so the bundle sits tight to the frame.
Match the bundle to the steel. On walnut, the rail is painted black: dark cables against dark steel more or less disappear. On beech, the rail is painted white: white or pale-grey sleeves look calmer than a black brick of cord. Hug the steel either way. Do not let the run swing in open air under the screen.
STUDIO already has clips for this. Use them. One leg, then lock the casters so you are not rolling over the lead.
Keep the run to the wall short
The ugliest cable is the one crossing open floor to a far socket. Put the stand near an outlet if you can, so the drop from the bundle to the wall is short and mostly behind the piece. If the socket is awkward, one short extension behind the stand, plugged in once and left, beats three long leads heading off in different directions.
If you rent, you cannot chase cables into the wall. That is fine. Skirting is a perfectly honest path. The renter's piece is written for that room.
The honest part
An open stand will never make cables vanish the way a closed cabinet with a back panel does. That is the trade: you lose a hiding place and you gain a low, light piece that keeps the screen where your eyes are. Aim for one tidy line. If total concealment matters more than the open look, you want a different object, and we would rather you knew before you buy.
Do not wall-mount the screen above the stand and then complain about the gap. That run is more exposed, which is one more reason we make the case for the floor.
