Is gopro 7 black 2.7k Linear mode 24fps rectified or crop from 4k wide?
Which mode has better resolution if i want to video over a small region like in a room?

Wide FOV provides a fisheye effect to the footage, and selecting Linear view corrects the barrel distortion as it straightens horizons and verticals and narrows the perspective.
As far as I know, 2.7K is pretty much close to in-camera Linear view for 4K that you can get.
While Linear FOV is not available on 4K resolution, I suggest that you can use Lens Correction functions on 3rd party editing applications. Or you can also use 2.7K and just upscale it to 4K. You can check this list of editing applications that work well with GoPro files as shared by a Hub member.
There are also some software suggestions in THIS ARTICLE that will help.
If you would like product or tutorial videos to better understand this, I recommend searching online video hosting websites (such as Youtube, Vimeo, etc) for published videos or other 3rd party generated content.
Hopefully this helps!

Thank you very much for your suggestion : )
I try 2.7 linear mode and 4k then take snapshop pictures. The pictures from 2.7k linear mode 24fps have the best resolution among any mode with higer fps and have equivalent resolution to 4k 24fps. The colour in 4k mode is not stable, there is a lot of dots (noise) in the pictures and the colour is not smooth as 2.7k 24fps mode. So, the fps has a significance effect. 2.7k 4:3 24fps linear mode is the best for me.
