Quick Answer
Choose a 240Hz IPS panel for the highest competitive frame rate and a 144Hz OLED for the best image quality. For pure esports the 240Hz IPS wins on motion clarity at high fps; for mixed single-player and competitive play, the 144Hz OLED's contrast and sub-1ms response are the more satisfying all-rounder.
Refresh versus image quality
A 240Hz IPS panel gives more frames on screen, which matters in CS2 or Valorant where you can push 240-plus fps with an RTX 5070-class card. A 144Hz OLED caps at 144 fps but delivers near-instant pixel response (around 0.03ms) and true blacks that IPS cannot match. So the choice splits along how competitively you play versus how much you value image depth.
Pricing and the practical pick
A 27-inch 1440p 240Hz IPS panel runs roughly R6,000-R9,000, while a 27-inch 1440p 144Hz OLED sits nearer R14,000-R18,000. If you mainly grind ranked shooters, the cheaper 240Hz IPS is the sharper competitive tool. If you play a mix of story games and competitive titles and game in controlled light, the 144Hz OLED's contrast makes everything look better, justifying the premium.
FAQ
Is 240Hz IPS or 144Hz OLED better for gaming?
240Hz IPS wins for competitive frame rate and costs less; 144Hz OLED wins for contrast and response in mixed play. Pick by whether you prioritise frames or image quality.
Does OLED's lower refresh hurt esports?
A 144Hz OLED caps lower than a 240Hz panel, which competitive players notice. Its near-instant response helps, but for pure ranked shooters the 240Hz IPS delivers more usable frames.
How much more does the OLED cost?
A 144Hz 1440p OLED runs roughly R14,000-R18,000 versus about R6,000-R9,000 for a 240Hz 1440p IPS. The OLED premium buys image quality, not frame rate.
Pro Tip
If you mainly play ranked shooters, the 240Hz IPS gives more usable frames for less money; if you play a mix and game in controlled light, the 144Hz OLED's contrast is worth the premium.
