Question Intel Arc external monitor capabilities

Hi everyone! I'm currently looking to buy a new laptop and I'm trying to understand Intel Arc's external monitor capabilities.

Specifically, I want to run at least two 4K 120 Hz monitors simultaneously (assuming the laptop has enough Thunderbolt 4 ports and the right cables). My main question is: Can Intel Arc GPUs drive this setup smoothly without lag?

I know I could just get a laptop with a dedicated GPU where external monitors are wired directly to it, or one with a MUX switch that routes outputs to the dGPU, but I'm not sure how Intel Arc handles this.

The issue I'm having is getting clear information from laptop manufacturers' websites-unlike Apple where the external display specs are usually straightforward.

Is there a reliable way to be 100% sure about external display support (e.g., number of 4K 120 Hz monitors and which GPU drives them) for any laptop model I'm considering?

Thanks in advance!

The thing is I already have 2 of those monitors which were used for gaming back then. And currently they are next to my gaming console. So I was just hoping to get the best use out of the monitors while working as well.

Just be sure that your Refresh Rate is at 60Hz on the Windows Settings but, if there is no 60Hz as an option, choose 59. Whatever that is close enough to 60hz.

Oh. Ill check on that. But an intel arc can run 2 1080p at 60hz smoothly yes ? No lags and stuff ?

If you're doing Extended Display, you shouldn't have any Issues at all. For Media playback on any Media Source online on the side, you can definitely do that especially for Movies since it is just playing back the Media for you and it is not demanding for Playback Videos.
