2018: HP 25f Review: Almost-Glossy 75hz IPS with AMD Free-Sync: 25er & 25es successor with AMD Free-Sync, native 75hz, the fastest pixel response times, but worse color accuracy than the 25er & 25es, and lower color space coverage than the older models.

2017: HP 24 Envy Review: Semi-Glossy 1080p IPS with 75hz & AMD Free-Sync: The 24 Envy natively supports 75hz (no overclock required), can cover more of the HDTV/REC 709 color space than the 25-27" HP monitors, but is less accurate than the HP 25er and 25es.

2016: HP 25er/es Review: Non-overclock-able 2016 Almost-Glossy/Low Haze Monitors with slightly more accurate color presets, 2x HDMI and 1x VGA.

2015: HP 27CW, 25XW and 27XW Review: Overclock-able 2015 monitors with worse preset color accuracy than the 25er and 25es.

The 25" and 27" HP CW/er/es/XW series monitors all use the same almost-glossy (Low Haze) coating which HP describes as:

"The reflective-ness typical with glossy screen surface is appreciably reduced with the Low Haze Screen enhancement, without losing clarity and contrast of screen imagery."

HP 25-27VX: These monitors use LED PWM Dimming or Flicker which ruins motion clarity and makes some people suffer from health issues like headaches and/or eyestrain. The VX monitors have less vibrant colors since they have a smaller and less accurate color gamut capable of covering up to 92% of the sRGB color space versus the 25-27CW & XW monitors 97%, and use a pure glossy coating while the 25-27 CW & XW monitors use a treated glossy or almost-glossy coating with some ant-reflective properties.

Review Information and Methodology:

Spoiler (hover to show)All testing done using an i1 Display Pro Colorimeter (a colorimeter measures the colors, contrast, brightness, gamma, ect), basICColor 5 (used to measure the color presets ), HCFR (software used to measure the color presets) and dispcalGUI for calibration. I used my own HDMI cable to connect the monitors to my PC and consoles.

PixPixAn's (free software) Chase, Streaky Pictures and Flag tests were all used to test the pixel response times along with the Ghosting test from Test UFO. Input lag was tested with the SMT Tool 2.5.1.

LCD monitor test images test patterns from Lagom were used to test the colors along with tons of photos from Wallpapers Wide.

Features & Stand

HP 24 Envy Front & Back by Deepinthesky Teslastorm, on Flickr
The HP 24 Envy uses a new variant of the Almost Glossy or Low Haze coating the HP 25-27 CW/er/es/XW monitors use, and the 24 Envy has a thinner fake-frame-less casing which they named a four sided micro-edge frame. The HP 24 Envy has a short stand which only tilts, Displayport, HDMI and USB-C. It natively supports 75hz, as well as AMD Free-Sync (requires compatible AMD graphics card) and comes with a VESA stand adapter.

The Dell S2418H and S2718H also use the same border-less casing/bezel; close up of the S2718H from the Dell S2718H Review by Alexander Gryzhin (=DEAD=).

Menu & Set-Up

DSC_0439 by Dr NCX, on Flickr
Unlike the HP 25-27 CW/er/es/XW monitors the HP 24 Envy does not need to have its contrast reduced and only has one setting which needs to be changed which is the Video Overdrive setting which controls the monitors pixel response times. The Video Overdrive setting needs to be switched from Level 1 to Level 2, or 3; these settings are available under the Image Control Menu located in the main menu. For more information about the ghosting/overdrive/pixel response times refer to the Ghosting section of this review.

The AMD Free-Sync setting, Gaming - Free-Sync, in the Viewing Mode Menu must also be manually activated to enable Free-Sync with compatible AMD graphics cards and the Xbox One X.  The Gaming - Free-Sync setting locks the color (Red, Green and Blue) controls, but not the Brightness and Contrast settings, and it provides the same preset color accuracy as the default setting.

Flicker/PWM Dimming

DSC_0438 by Dr NCX, on Flickr
The HP 24 Envy, 25" & 27" HP CW/er/es/XW series monitors are not advertised as being Flicker Free even though they do not use LED PWM Dimming (read about the side effects), regardless of high or low the brightness is set. LED PWM Dimming was tested for using the Blur Busters Test UFO Blur Trail/PWM Test from 0-100% Brightness. The lack of PWM is a good thing since PWM or Flicker ruins motion clarity (example), and makes some people suffer from health issues such as headaches, and/or eyestrain.
