Quick Answer: The LG 27″ 180Hz (27GS40W-B) is the better gaming monitor overall. If you’re deciding whether to spend the extra $50 to upgrade from the LG 27″ 144Hz (27G411A-B), it’s worth it if gaming matters to you.
Introduction
You’ve found the LG 27G411A-B at $89 and you’re wondering: is the 27GS40W-B at $139 worth the extra $50? Both are 27-inch IPS UltraGear monitors from LG. Both look nearly identical in photos. The difference is in the specs that actually affect how the monitor feels day-to-day — and for gaming specifically, the 180Hz model does pull ahead in meaningful ways.
Quick Comparison
| LG 27G411A-B (144Hz) | LG 27GS40W-B (180Hz) | |
| Price | $89 | $139 |
| Refresh Rate | 120Hz / 144Hz OC | 180Hz native |
| Response Time | 1ms MBR | 1ms GtG |
| HDR | HDR10 ✅ | No ❌ |
| G-Sync | Yes ✅ | No ❌ |
| FreeSync | FreeSync | FreeSync Premium |
| Our Score | 8.4/10 | 8.8/10 |
Refresh Rate — 27G411A-B vs 27GS40W-B
The 27G411A-B runs at 120Hz natively. You can overclock it to 144Hz in the OSD — and it holds stable at 144Hz — but it’s an extra step, and the ceiling is lower than the 27GS40W-B’s native 180Hz. For most gaming genres, 144Hz is plenty. For competitive FPS where every frame counts, 180Hz is the stronger position.
Winner: 27GS40W-B
G-Sync & Adaptive Sync — 27G411A-B vs 27GS40W-B
This is where the 27G411A-B punches back. It’s G-Sync Compatible, which means NVIDIA GPU owners get tear-free gaming with VRR. The 27GS40W-B is FreeSync Premium only — NVIDIA cards still work, but VRR support isn’t guaranteed. If you’re on an RTX GPU, the 27G411A-B is the safer VRR choice.
Winner: 27G411A-B (for NVIDIA users)
Response Time — 27G411A-B vs 27GS40W-B
Both are listed at 1ms. The methods differ: the 27GS40W-B uses GtG (grey-to-grey), which measures actual pixel transition speed. The 27G411A-B uses MBR (Motion Blur Reduction), achieved through backlight strobing. GtG of 1ms is generally considered the more honest gaming spec. In practice, both look fast and responsive.
Winner: 27GS40W-B (GtG vs MBR)
HDR — 27G411A-B vs 27GS40W-B
The 27G411A-B has HDR10 certification; the 27GS40W-B does not. That said, at the peak brightness both panels offer, HDR10 doesn’t deliver a dramatic visual upgrade. It’s a nice-to-have if you want content compatibility, but not a reason to choose one over the other for gaming or design.
Winner: 27G411A-B on paper — but marginal real-world impact
Value — 27G411A-B vs 27GS40W-B
The 27G411A-B at $89 is genuinely excellent value for a 27-inch IPS monitor. The 27GS40W-B at $139 is also excellent value for a 180Hz gaming monitor. Whether the $50 delta is worth it depends entirely on what you’re doing with it.
Winner: 27G411A-B on absolute price — 27GS40W-B on gaming performance per dollar
Use Case Breakdown
Stick with the LG 27G411A-B (144Hz) if:
- Budget is hard-capped at $90
- You have an NVIDIA GPU and want guaranteed G-Sync VRR
- Gaming is casual — you don’t care about the last few Hz
Upgrade to the LG 27GS40W-B (180Hz) if:
- Gaming is your primary use case
- You’re on AMD GPU and want FreeSync Premium
- You want native 180Hz without OSD tricks
Verdict
For $50 more, the 27GS40W-B gives you native 180Hz, a better FreeSync implementation, and a cleaner 1ms GtG spec. For gaming setups, that upgrade is worth it. The 27G411A-B’s main wins — G-Sync Compatible and HDR10 — matter specifically to NVIDIA GPU owners or media consumers. Choose based on your GPU and how seriously you game.
