My TV entertainment unit is 52cm in height, I think it's about 10cm to 20cm too low for a 65" TV on a 52cm entertainment unit. I sit in my office chair to game and watch TV. I prefer to look straight or slightly up.
Has anybody solved this problem with a reliable solution worth putting your more expensive TV investment on?
Plenty of options for table top vesa mounts.
Even a floor standing vesa stand and then you can back your etu on it.
Years ago I went the diy route as the above was not so common. Took a timber panel framed with pine 20x30mm lengths, screwed it to the etu using some 90degree brackets and fixed an aldi articulated vesa mount to it.
Bout a $100 and it looks great , held our 55" for years and now holds a 65" with ease.
