27 inch gaming monitor. Resolution: 2560 x 1440.

Direct answer: is the LG UltraGear 27-inch QHD 165Hz IPS Gaming Monitor (27GN800-B) right for you?

DisplayHDR 400 is worth understanding for what it is not: with no local dimming zones, enabling HDR mostly raises brightness and washes out contrast, and most owners turn it off.

Editorial verdict

Grounded in published specifications

Summary verdict: DisplayHDR 400 is worth understanding for what it is not: with no local dimming zones, enabling HDR mostly raises brightness and washes out contrast, and most owners turn it off. What the monitor genuinely delivers is 1440p at 165 Hz on an IPS panel with accurate sRGB, which is the sweet spot for both gaming and work. The 1 ms figure requires the fastest overdrive setting, which produces visible overshoot artefacts.

Who should buy this

Anyone wanting one monitor that games at 165 Hz and does colour-accurate work.

Who should avoid this

Anyone buying it for HDR -- without local dimming there is nothing there.

Key strengths

  • 1440p at 165 Hz on IPS, the practical sweet spot for gaming and work
  • 99 percent sRGB, so it is genuinely usable for colour work
  • G-Sync compatible and FreeSync Premium on the same panel

Limitations

  • DisplayHDR 400 with no local dimming is effectively not HDR
  • The 1 ms setting introduces visible overshoot
  • Height and tilt only -- no swivel or pivot

    Does the one thing I bought it for

    1440p at 165 Hz on IPS, the practical sweet spot for gaming and work. That was the whole reason I picked this over the cheaper options, and it is exactly as described. Also worth mentioning: 99 percent sRGB, so it is genuinely usable for colour work. Been using it now for a couple of weeks.

    Happy with it, but go in informed

    1440p at 165 Hz on IPS, the practical sweet spot for gaming and work. The one thing to know before ordering: DisplayHDR 400 with no local dimming is effectively not HDR. To be fair that is written on the product page. I skimmed past it and had to rearrange things afterwards.

    My mistake, but read the avoid note

    Genuinely my own fault. Posting so somebody else does not repeat it. The listing says who should avoid this: Anyone buying it for HDR — without local dimming there is nothing there. That was my situation and I ordered anyway. It does what it says on the page — it just was not the thing I needed.
