Xbox 360 & Xbox One

The HP 25-27 CW/er/es/f and 24 Envy monitors scale 1280x720 and 1920x1080 without issue, but the Xbox 360 must have its YCbCR709's setting selected to prevent the image from being washed out since the other settings send a 16-235 signal.

The HP 25f automatically reads both the Limited (16-235) and Full (PC RGB 0-255) signals sent out by the Xbox One and Xbox One X, and supports Free-Sync with the One S and One X if the Free-Sync setting is selected (Color Control Menu>Viewing Modes>Gaming FreeSync), and if the Allow variable refresh rate setting is selected in the Xbox One S and X's Display & sound Advanced video modes menu.  Here's how to access this setting:

Bleeding Glossy 75hz Adventurer

Conclusion

DSC_0674 by Dr NCX, on Flickr

+Affordable
+Stable stand
+Two HDMI inputs and one VGA input
+AMD Free-Sync
+Native 75hz
+Low Haze or Almost-Glossy coating is completely grain free and enhances clarity and color vibrancy
+Very high brightness compared to older models makes the 25f suitable for very brightly lit environments, and possibly outdoor use as long as the monitor is not facing the sun
+High pre-calibrated contrast for a non-VA panel
+No need to reduce contrast from 80 to 75 to remove green tint from greys unlike the older 25" & 27" CW/er/es/XW monitors
+Fairly accurate and vibrant color presets
+Free-Sync and Custom Color mode image quality is the same
+Wide viewing angles
+Minimal IPS glow when the brightness is not cranked in a dark room and viewed from the correct height
+Response Time Level 4 significantly speeds up the pixel response times without obvious overshoot ghosting
+Faster pixel response times and less overshoot than older models
+Negligible input lag

-Very obvious back-light bleed in the bottom left corner
-Light preset green tint
-Inability to cover the HDTV/REC 709 and sRGB color spaces, though this is normal for monitors in this price range
-The best overdrive (Response Time) setting is not preset
-Free-Sync mode locks the color controls
-Frame-less casing has an inner black bezel which reduces the perceived black depth
-Not VESA Compliant


The HP 25f offers a few improvements over the older models which are the inclusion of AMD Free-Sync, a native 75hz refresh rate, properly preset contrast (no need to drop the contrast from 80 to 75), faster pixel response times (Response Time Level 4) and vastly higher maximum brightness which makes the 25f suitable for use in very brightly lit environments.  The 25f is slightly less accurate than the 25er and 25es monitors I tested in 2016, has a slightly smaller color gamut which prevents it from being able to display colors as accurately and vibrantly as the older models, and the 25f I tested suffered from very obvious back-light bleed in the bottom left corner.  The inability to edit the color controls when the Free-Sync mode is selected is a non-issue since most people do not own a colorimeter which is required to properly calibrate a display. 

The HP 25f is a good budget gaming monitor, especially since there are no alternatives with the same coating and features.  The HP 24 Envy from 2017 supports AMD Free-Sync and 75hz naitvely, and has slightly better image quality and less glow, but costs more as well as suffers from <1mm thick black vertical lines which are visible when viewing blue and oranges, and uses an inferior semi-glossy coating which looks worse than the almost-glossy or low haze coating the 25f uses when exposed to bright lighting.  The Dell S2718D is the only higher end or more expensive alternative with a non-matte coating, AMD Free-Sync and 75hz, but it uses the same semi-glossy coating as the HP 24 Envy which looks washed out when exposed to bright lighting, and the S2718D looks grainy when viewed off angle.
