Should I upgrade my monitor for cs2 ?

I actually play on a BenQ Mobiuz EX2710Q monitor. It’s a 27-inch, 2K, 165 Hz monitor.

My main issues with it are:

1. It sometimes feels too big and strains my eyes.

- My crosshair is too thin compared to a 24" monitor.

- I can’t get the resolution I want because of the 2K; it causes stretching and blurring.

Should I upgrade to a 24" monitor with a refresh rate of more than 240 Hz in 1080x1920?

I see two options:

ZOWIE XL2546K (FHD 1080p, 24.5", 280Hz)

Pros: DyAc+

Cons: Fast TN panel (heard bad things about TN panels vs. fast IPS) + expensive

2. Any good 240 Hz monitor. A fast IPS panel with 0.5 ms response time for a third of the price of the Zowie.
