Every unit goes through these checks before it is graded, priced and listed.
PANEL AND BACKLIGHT
Full-screen white, black, red, green, blue. Look for dead pixels, marks, uneven backlight.
HDMI INPUT
Boot a source on each HDMI port. Confirm picture and native resolution.
DISPLAYPORT INPUT
Same as HDMI. N/A if the unit has no DisplayPort.
REMAINING INPUTS
VGA, DVI, USB-C, USB hub, audio out. Test each one that exists.
BUTTONS AND MENU
Every button or joystick direction. Open the OSD, change a setting, confirm it sticks.
STAND AND HINGE
Tilt, height, swivel, pivot where fitted. Check it holds position and does not wobble.
POWER AND STABILITY
Cold start from unplugged, then 30 minutes on. Listen for coil whine, check for flicker.
COSMETIC CONDITION
Bezel, chassis, rear, cable entry. Photograph every mark you can see from 50cm.
THE FIT CHECK
Worked out from this screen's own specs — size, resolution, panel, refresh rate and ports. Including the jobs it is the wrong screen for.
Office and admin
Two full documents side by side without a second screen.
Spreadsheets and finance
Far more columns visible before you scroll sideways.
Coding and development
Editor, terminal and browser side by side on one screen.
Video editing
The timeline stretches wide — far less zooming in and out.
Films and streaming
Cinema-shaped: widescreen films fill the panel edge to edge.
Study and research
Notes and source material open side by side.
Design and photo work
IPS colour and enough resolution for layout work.
Casual gaming
75Hz gives a small but real bump over 60Hz.
Laptop docking
Connects over HDMI — you keep the laptop charger plugged in.
Competitive gaming
Under 100Hz — buy a high-refresh screen if ranked FPS is the point.
