For most gaming, 144Hz is a solid baseline — fast enough that motion looks smooth and inputs feel responsive. Competitive players running fast-paced titles benefit from 240Hz and above, where the difference is measurable. If you mostly play slower-paced or single-player games, 60–75Hz is perfectly workable.

Yes. IPS panels deliver accurate colour and wide viewing angles — good for general use and titles where image quality matters. VA panels offer deeper contrast, which helps in darker scenes. TN panels have the fastest response times but narrower viewing angles and weaker colour. OLED sits apart: per-pixel lighting gives true blacks and near-instant response, at a higher price point.
