@Line_080889 Your laptop's graphics card can render images in 4k or higher, and it can generate as high a refresh rate as it can keep up with. There's no theoretical limit here other than what's built into software. The problem is the actual workload of running Sims 4 in 4k. The game is not particularly heavy by current standards, but the sheer number of pixels on a 4k screen means a high workload. The more demanding it is to render a single frame, the fewer frames per second the graphics card can render.
The limits you're seeing, both resolution and refresh rate, are from the monitor and TV, not from the graphics card. Windows will only offer you settings that the monitor currently in use can support, regardless of the graphics card's capabilities.
The other limitation to consider is the connection between the laptop and monitor, for example DisplayPort or HDMI. The generation matters here: HDMI 2.0 can handle more data than 1.4, which translates to a higher limit on resolution and refresh rate. To find out what your laptop uses, I'd need the exact model.
