For passive copper, anything over 25' starts entering problematic areas,
and over 50' is a no-go if you want any expectation of reliability. There
are active copper cables (they have integrated repeater electronics) that
will work in the 25-100' range.

But for 25 meters, you might want to look into optical HDMI cables. I
personally have not used them yet but they keep coming up when I'm
researching designs, and I'm sure I will use them soon. Here are two
sources:

They are, of course, more fragile than copper cable, and more expensive,
but theoretically more reliable. At 25 meters you have a choice between
active cooper and fiber, depends on your environment. Be aware of
environmental noise that can interfere with long copper runs.
