Out of the box, greyscale performance is average. The X27q ended up a bit too warm, and the gamma was too high, making some shades darker than they should be. This caused weak deltaE performance. HP doesn't include an sRGB mode with this display, and there are only a few other color controls, so overall the only major adjustment you can make is to the white balance. This can improve grayscale performance, but we end up shy of accurate results. Meanwhile at 60Hz, we have to drop down the overdrive setting and as there's no option between Level 2 and Level 1, we basically have to disable overdrive. This hurts performance and doesn't make the X27q a very suitable low refresh rate monitor. If you're mostly playing around 60 FPS I'd recommend you get the M27Q instead, or even the S2721DGF depending on your budget. At a fixed 120Hz, the X27q is passable, delivering similar response times to other monitors, but with a higher level of overshoot. The panel isn't quite as good as others at the top of this chart, but good enough that it's still usable at this refresh rate. Besides, even if sunlight hits the screen, which is a bad thing for a lower brightness ratio, this one can manage it effectively and without struggle.

In terms of picture quality, there's not much wide gamut support, factory calibration is average, and the contrast ratio is poor. But other areas are perfectly usable, it gets nice and bright, viewing angles are excellent, it's a flat panel, no dark level performance issues and it works perfectly fine for SDR content.

HP X27 FHD Gaming Monitor

All performance specifications represent the typical specifications provided by HP's component manufacturers; actual performance may vary either higher or lower. Results may vary based on quality of the original picture/photo/video and difference between the previous monitor settings compared to the HP Enhance + mode.

As we continue to review the displays in this “X” HP lineup, we’re beginning to wonder why it doesn’t get the acclaim it deserves.When we move up to Level 2 overdrive, this is where the monitor is most usable at 165Hz. Performance improves significantly to a 6.13ms grey to grey average, and although overshoot has also increased, it's to a minimal level that you won't notice while gaming. Cumulative deviation is also now around a more acceptable level, with a score of 500 being around the average we like to see for this class of monitor. Note: This tool applies to Microsoft Windows PC's only. This tool will detect HP PCs and HP printers. The only other 1440p 240Hz TN monitor currently available (not yet in the US) is the Lenovo Legion Y27GQ-25. What’s more, since there are only 16 dimming zones, they cannot quite keep up with fast-moving objects, which will introduce noticeable trailing/glowing. So, for fast-paced gaming, make sure local dimming is disabled.
