Refresh Rate
60Hz: Standard office monitor. Not for gaming.
144-165Hz: The sweet spot. Noticeably smoother than 60Hz, affordable, easy to drive with mid-range GPUs. This is where you should be.
240Hz: Competitive FPS advantage. Requires a strong GPU to push those frames. Diminishing returns vs 144Hz for casual gamers.
360Hz+: Esports only. You won't notice the difference unless you're top 1%.
Resolution
1080p (1920×1080): Easiest to drive, highest FPS. Sweet spot at 24-25". Looks soft at 27"+.
1440p (2560×1440): The current gaming sweet spot. Sharp at 27", good balance of clarity and performance. Needs at least an RTX 3060 Ti / RX 6700 XT.
4K (3840×2160): Stunning clarity, demanding on GPU. Better at 32"+. Needs RTX 4070 Ti Super / RX 7900 XT or better for high FPS.
Panel Types
IPS: Best colors and viewing angles. Modern 'Fast IPS' panels rival VA for speed. Most common and recommended.
VA: Better contrast (deeper blacks), slightly slower pixel response. Good for immersive single-player games, can have ghosting in fast FPS.
TN: Fastest response times, worst colors and viewing angles. Obsolete for most users — only relevant for extreme budget competitive setups.
OLED: Perfect blacks, instant response, incredible HDR. Expensive, risk of burn-in over years. The premium choice.
Adaptive Sync
G-Sync (NVIDIA) and FreeSync (AMD) eliminate screen tearing without the input lag of V-Sync. Both work cross-brand now — most FreeSync monitors work with NVIDIA GPUs as 'G-Sync Compatible.' Make sure your monitor has at least FreeSync Premium.
Brand Tiers
Budget ($120-200): AOC, Acer Nitro, Gigabyte G24F. 1080p 144-165Hz IPS — outstanding value.
Mid-Range ($250-400): Dell S2722DGM, LG 27GP850, Gigabyte M27Q. 1440p 144-170Hz IPS. The sweet spot.
Premium ($500-1000+): Samsung Odyssey OLED, Alienware AW3423DWF, ASUS ROG Swift OLED. OLED panels, 240Hz+, ultrawide.
What to Avoid
60Hz monitors for gaming — just don't. 1080p at 27" or larger — pixels visible. Curved monitors under 30" — pointless. '1ms MPRT' marketing (not the same as 1ms GtG). Built-in speakers as a deciding factor — they're all terrible.
