It felt a little flimsy
s definitely missing other nice to have features
the monitor doesn t look too bad
monitor isn t very adjustable
it does not feature any adaptive sync technology
BenQ monitor are not amazing
the Samsung is a little weird
eliminates tearing and stuttering at even very high frame rates
backlight is not PW-modulated at any brightness level
The display shakes back and forth as you shake the desk
the image gets a little washed out as the angle grows
it is a bit too bright
inability to change in that amount of time
the image degrades when viewed at an angle
TN panels will generally suffer from color shifts
some scenes will be too bright
Sony TV Wi-Fi No Internet Access Issue
still it s not as great as an IPS panel
Some colors are still inaccurate
its fixed design with no adjustments for either tilt of height
KG251Q cannot be adjusted for either tilt or the height
No cherry-picked units sent by brands
does not have an optional black frame insertion feature to reduce persistence blur
the viewing angles are narrow and cause the image to shift in color
