Passive HDMI baluns are hit or miss. Some work okay, some work very well, some don't work at all. With higher resolutions, most don't work very well. So, no guarantees on 1080p or higher resolutions with passive baluns. HDBaseT WILL work, and you will pay for it.
At 25' with drywall open I would do the following.
1. RUN ONE INCH CONDUIT! Seriously! WTF are you thinking? If you have open walls, then put in the only true future-proof option! Put a piece of 1" conduit (or larger) between your equipment and the display so WHEN technology changes, you have a way to add wiring as you need it.
2. RUN PASSIVE HDMI - Do not use Redmere behind drywall. It's an active product with electronics which can fail. A number of reported reviews of cable failure are out there. Instead use this cable:
That's a 25' high speed rated HDMI cable. It's 30 bucks and by HDMI standards should handle all the HDMI 2.0 formats at 18+ GBs data rates, so you should be good for years to come.
Why buy $30 balun that likely won't work, or a $200 balun that will work, when you can buy a $30 cable which WILL work, and is good for years to come without active electronics in the mix to mess everything up? Keep it simple.
