The BOE NV156FHM family is one of the most common 15.6-inch laptop panels in the world — but it is not a single screen. It is a whole series of panels that share a size and resolution while differing in refresh rate, connector and color gamut. If you have seen codes like NV156FHM-NX3, N4K, N48 or N4G and wondered how they relate, here is how to read the series and pick the right one.
What “NV156FHM” actually means
The code breaks down like this: N = BOE panel, V = a product line indicator, 156 = 15.6-inch, and FHM = Full HD, i.e. 1920×1080. So every NV156FHM panel is a 15.6″ 1920×1080 screen. What changes is everything after that — the suffix.
How to read the suffix
The two or three characters at the end (the “-NX3”, “-N4K” part) identify the specific variant: its refresh rate, panel generation, connector pin count and sometimes its color gamut. This is the part that decides whether a panel will work in your laptop, so it is the part you must match exactly.
Common NV156FHM variants
| Variant | Refresh | Connector | Typical use |
|---|---|---|---|
| N4K / N48 / N4S / N4G | 60Hz | eDP 30-pin | Standard office / home laptops |
| NX3 / NX4 | 144Hz | eDP 40-pin | Gaming laptops (ASUS ROG/TUF, etc.) |
| NX9 / NXA | 144–165Hz | eDP 40-pin | Higher-refresh gaming models |
These are the typical configurations, but BOE produces many sub-versions (V8.0, V8.1 and so on) and occasionally changes specs between revisions. Always confirm against the exact code and version printed on your panel rather than assuming from the suffix alone. Our guide to finding your panel model number shows where to read it.
Are NV156FHM panels interchangeable?
Not freely. A 60Hz 30-pin variant and a 144Hz 40-pin variant are not interchangeable — they use different connectors and the laptop’s cable and board have to match. Within the same refresh rate and pin count, many variants are cross-compatible, which is why a repair often has several valid options. The safe rule: match the size (15.6″), resolution (1920×1080), connector type, pin count and refresh rate. If all of those line up, the panel will work even if the exact suffix differs.
How to pick the right one
- If your laptop is a standard 60Hz model, you want a 30-pin variant (N4K, N48, N4S, N4G or an equivalent from another brand).
- If it is a 144Hz gaming laptop, you want a 40-pin variant (NX3, NX4 or equivalent).
- Color gamut (45% NTSC standard vs 72% NTSC / 100% sRGB wide-gamut) is worth matching if color accuracy matters to you.
- Cross-brand equals exist — AUO B156HAN, Innolux N156HCA and others can substitute for an NV156FHM with the same specs.
