What makes a 3d monitor support 3d?
Is there a software inside the monitor which enables 3dvision? CAuse i really want to see how my pc handles 3d in 4k.

If you're talking about 3D Vision specifically, it needs to meet the higher physical demands (like being 120hz), and just as importantly, the company needs to drop a bag of cash at Nvidia's headquarters or Nvidia will block it from working (in the drivers). There's no software inside the monitor. It's just whether the company has paid to have it whitelisted in the GPU drivers. The whitelist is what determines whether it works or not (Assuming it even has the technical prowess to begin with).

To give nVidia some credit, 3D Vision monitors have to support Lightboost (for maximum brightness while minimising ghosting), and I believe there's some level of polarisation as well (because the glasses are polarised as well as shuttered). So it's not just a money thing, possibly. But yeah, it does need to be certified by nVidia to work, and I don't believe there are any certified 4K 3D monitors. Even if there were, I can assure you that most games would run extremely poorly. It would require a framerate of 120fps, which you won't be able to manage on most modern games without seriously dropping settings a lot.

Well, most games in have played in 1080p at 120 fps did not drop in fps at all when i activated 3d. So 3d in 4k would not drop the fps that much either i guess.

4k has four times as many pixels compared to 1080p. To get 60fps in 4k requires approximately 4 times the processing power of 1080p. Then double that again for 120fps.

3D Vision requires approximately twice the GPU processing than 2D. The reason why most of your games have little framerate difference between 2D and 3D in 1080p is because your computer is overpowered compared to this particular game's needs : you have reached the maximum framerate the game can handle and your GPU is partially idling. If you go to 4K you'll reach the GPU limit in most games and feel the big difference in framerate. But beyond the GPU vs game aspect, there is a much tighter bottleneck on the hardware side. In order to do 3D Vision in 4K, you have to transmit a full resolution 4K picture from the GPU to the display at 120Hz. This is beyond the maximum capabilities of Hdmi 2.0 and beyond DisplayPort 1.2. You'd need DisplayPort 1.3 which was standardized last year. DP1.3 GPUs and Displays are not available yet. There is a possible work around by using dual DP1.2 transmission and tiling the display. It's how 4K used to be done before hdmi2.0 and Displayport 1.2 were available, and Nvidia does have the technical expertise to make it work : it's an Nvidia 3D + surround configuration with 2 vertical displays, but you'll probably won't see it done. First you'll need a courageous monitor manufacturer implementing the Dual DP1.2 input configuration, and then you'll need NVidia to update 3D Vision drivers. All of this knowing that it will be obsolete next year with proper native DP1.3 GPUs and Displays. They'll probably wait one more year.
