The Norvik NX27-Q240 is a 27-inch QD-OLED gaming monitor with a 2560 × 1440 resolution and a 240Hz refresh rate. It targets players who want near-instant pixel response and perfect blacks without stepping up to a 4k panel. It connects over HDMI 2.1, DisplayPort 1.4 and USB-C with 65 W charging, and it ships with a stand that adjusts for height, tilt and swivel but does not rotate to portrait.

Demo rubric. Each scored metric is mapped linearly onto 0–10 between a 'worst' and a 'best' anchor and clamped. A test group score is the weighted mean of its metric scores. A usage score is the weighted mean of its group scores; groups marked not applicable are dropped and the remaining weights are re-normalised. The overall score is the mean of the four usage scores. Anchors and weights are placeholders until HannahRev publishes its production methodology.
An outstanding monitor for gaming in a dim room. Motion is extremely clear, input lag is negligible and HDR highlights look vivid thanks to the wide colour volume. Its limitations are the glossy coating and modest full-screen brightness, which make it a weaker choice for a sunlit office.
Key measurements against the alternatives we recommend considering.
We compared the NX27-Q240 with three demo alternatives. The Vireon V32-W240 is the closest rival: it is larger and sharper at 4k but its RWBG subpixels make text slightly softer. The Kestrova K27F-180 shares the resolution at a much lower price but cannot match the contrast or motion handling. If HDR brightness matters more than speed, the Solenne Vista 34C's Mini-LED backlight gets far brighter.

Norvik NX27-Q240
Vireon V32-W240
Two OLED gaming monitors at different sizes: the NX27-Q240 is the better choice for bright colours at 1440p, the V32-W240 for a larger, sharper 4k image.
Norvik NX27-Q240
Kestrova K27F-180
The same resolution at very different prices. The NX27-Q240 is far better in dark rooms and in motion; the K27F-180 is the sensible budget pick for bright rooms.
Norvik NX27-Q240
Solenne Vista 34C
The Vista 34C gets much brighter in HDR and offers an ultrawide field of view; the NX27-Q240 is clearly faster and has perfect blacks.
Norvik NX27-Q240
Vireon V27-Q360
Both are 1440p QD-OLEDs. The V27-Q360 is faster at 360Hz; the NX27-Q240 adds USB-C charging and costs less to drive with a PC.

Contrast, brightness, uniformity and colour — the measurements that decide how an image actually looks.
| Metric | Result | Metric score |
|---|---|---|
| Native Contrast | ∞ : 1 | 10.0 |
Because each subpixel produces its own light, a black pixel is simply off. Dark scenes show no haloing or grey mist.
Ratio between the brightest white and the deepest black the panel can show at the same time. Higher contrast produces deeper blacks in dark rooms.
Contrast measurement (v0.1-demo): Checkerboard pattern measured with a colorimeter in a dark room, local dimming off unless stated.

|---|---|
| Local Dimming | Not applicablePer-pixel light control |
| Dimming Zones | Not applicable |
| Blooming Control Assessment | Not applicable |
Not applicable. The panel controls light at the pixel level, so there is no backlight to dim.
Whether the backlight can dim zones independently, and how well it avoids blooming. Self-emissive panels control every pixel directly, so this test does not apply to them.

| Sustained 100% Window | 245 cd/m² | 5.2 |
Bright enough for a dim or moderately lit room. Large white areas such as documents trigger automatic brightness limiting, so full-screen white is modest.
Luminance with standard (non-HDR) content. Real-scene peak reflects typical desktop use; the sustained full-screen value matters for bright rooms.

Small highlights reach about 1,000 cd/m², but brightness falls as the bright area grows. The HDR real-scene value is what most games and films will produce.
Peak luminance with a white window covering the given share of the screen.
Peak luminance in HDR mode across window sizes. Small highlights can get much brighter than a full white screen on most panels.
