G-STORY 15.6" Inch IPS 2K 120Hz Portable Monitor Gaming Display Integrated with PS5(not Included) 2560X1440 with 2 HDMI Ports,FreeSync,Built-in 2 of Multimedia Stereo Speaker,UL (2K&120Hz)

It does FHD/2K @120hz and 4K @60hz. Has HDR and Freesync. Everything looks incredible with beautiful colors and surprisingly deep blacks. I know it's definitely not for everybody but for me it's perfect.

Sure thing. https://www.amazon.com/G-STORY-Portable-Integrated-2560X1440-Multimedia/dp/B0B5STD76G Don't mind the two available options, the monitor does both resolutions and refresh rates. I tested it myself

I don't travel at all with the console. Main reason is the living room TV is in use by the wife or kid most of the time and the only way I could get some play time was at later hours, it wasn't really doable. This way I can have this on my PC desk and have some fun whenever it's convenient. Is it as cool as playing on a big TV though? No, it's not.

How's the response time? I see some sources say 3ms\~. I know on Rocket League it'll make your car feel way heavier on bigger response times. Currently I'm on a G-Story 2K 120hz 17.3" which is okay, but the refresh rate is still not as smooth as I'd want. So I wanna get that 2k 144hz 18" UPERFECT monitor. Would love to know if you have any issues with response time on high speed things like rhythm games (osu) or Rocket League. You won't notice it too much on slower stuff like Valorant or CS. Lmk! :D
