The average couple bickers over the TV four times a week - with what to watch, someone asking too many questions, and how high the volume should be, named as the biggest bugbears. A poll of 2,000 couples, who live together, found the television to be one of the most argued-about topics within the home.
Almost one in five (19 percent) get frustrated with their partner's TV habits on a daily basis - which has resulted in 44 percent moving to another room so they can enjoy programmes in peace.
Talking during a show, falling asleep mid-episode, and the height of the TV were also among the top 15 annoyances people encounter.
And more than a quarter of those (27 percent) who have rowed over the TV have even ended up buying another one as a result.
Meanwhile, 26 percent believe increasing the size of their TV would help reduce arguments.
Sally Nelson, director UK product at streaming service Roku, which commissioned the research, said: "We now know the typical Brit spends nearly 15 hours a week watching TV - and over half of that is with their partner.
"It is a big part of our lives, so no wonder it causes household squabbles."
When it comes to those with children, dads (51 percent) seem more bothered than mums (31 percent) about wanting full control over the remote at all times.
And 37 percent of all parents think arguments would be less common if their favourite seat was always left free.
But 56 percent would rather battle with their partner than their kids, when it comes to who has control over the remote and what to watch.
And 35 percent of all those polled would like an extra screen in the house to guarantee argument-free entertainment.
However, while one in ten reckon their telly is too small, five percent go the other way and think theirs is too big - although 85 percent are in the "just right" camp.
The research also found 42 percent have resisted the urge to put a TV in their bedroom - but seven percent caved, under duress from their partner.
When it comes to TV preferences, the study, carried out via OnePoll, found size matters the most for half of Brits, who consider screen size to be one of the most important features - followed by sound quality, and price.
Sally Nelson, from Roku, added: "Putting more screens in the house is probably one of the most effective ways to eradicate arguments over the TV.
"We have seen there is also an appetite for bigger screens - spearheaded by men - with 60 percent of Brits currently having a 50" TV or smaller at home."
