I have created a very simple TV room in the basement, have framed and put up chipboard, and now wondering how to make the seams look nicest? Is it filling and sanding that's required, or is there a smart way to make the seams disappear? I had planned to paint, wallpapering feels unnecessary...
In some places, it seems like a chipboard is a tad "tense," so there is certainly a 3-4 mm height difference between it and the next chipboard. Is it possible to fix without taking it down and putting up a new one? I'm not overly concerned with appearance, but if it can be easily fixed, it might be interesting

Yep, it will probably be about filling and sanding, and applying a paint strip as mats_o says. The 3-4 millimeters can probably be smoothed out with a wide enough putty knife (Make a very wide arc type), otherwise it might be an idea to go over the seams with an orbital sander before you apply putty.

I've now done some spackling and used painter's tape. It worked beyond expectations, and it feels like it's going to be completely smooth and nice before painting. I also plan to use a completely matte paint...
There is a high risk that the seams will show in the spring when the humidity is lower. I lived in a house with different types of wood fiberboards in some of the rooms, Tretex and particle boards. Neither painting nor wallpapering worked, the seams invariably showed every spring. Gypsum boards solved the problem.
I used strips and filler, and when it looked good, we glued thin, smooth fiberglass cloth that was painted. Looks good after 1 year without any visible cracks anywhere.
Paper strips are supposed to be stronger than fiberglass, which tends to stretch a bit.

Otherwise, chipboards are usually hopeless when it comes to neat seams. They crack most often! Unfortunately, my house has chipboard everywhere, we renovated everything when we moved in, but the first spring... the seams above/below the windows and doors have given way, "arched" and after a while, there were a few nice arches in the living room.
I should add that I used 3 layers of fiberglass in every seam to try to hold it together. But no - the force in the swelling/shrinking wood is enormous.
My advice is to always avoid chipboard under the surface layer!
As a screw fixture behind gypsum - okay. But never just chipboard.

Sometimes it can help if behind the seam you also have chipboard, glue-screwed, instead of a stud. The idea is that it will reduce movement since it's the same mtrl behind. It has worked for me on a heck of a lot of "kattvindar"...

I have now also applied fiberglass fabric, and hope that it will provide a slightly more durable and nicer surface. It will be interesting to see how everything looks when it is fully painted
