Why does my 144hz monitor jerky when I have OBS open on my 60hz second monitor?

I recently started streaming on Twitch and playing Fortnite there. My main monitor is a BenQ Zowie XL2411P (144hz) and my second monitor is a Samsung S22E390 (60hz). On the second monitor, I have programs such as Discord or just OBS opened (so you can see a stream preview of my stream [video]) and Fortnite is open on the main monitor, I limited the game to full screen and 240fps (because for me it is less input- delay to 240fps). Well anyway, when I have OBS open on the second monitor, it feels like I would play Fortnite at 60fps, which a 144hz gamer like me can see very strongly. What exactly can that be?

My PC Specs:

MSI RTX 2070 SUPER GAMING X TRIO
Ryzen 7 2700x
ASUS ROG STRIX B450-E GAMING (mainboard)
32GB DDR4 G.Skill RAM @ 3200mHz
SSD Corsair MP510 (960GB)
NZXT KRAKEN x62 WaKü
Corsair 750 watt power supply (Gold Plus certified)

Oja that's what annoys me about windows. I know it from resolutions. 4k TV and a cheap monitor. It just doesn't fit. You can mirror both but you have to fix the weaker monuture even if 4k is standing. Letting both of them run in front of each other is a children's disease because it recognizes the samsung television as having. Logical since it is the better monitur. And then if I want to see something I have to glow on my 50inch TV at a distance of 50cm. So in contradiction I have no idea about things and leave you alone or I say as I solved the problem.
