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
Comfortable for email, spreadsheets and browsing all day.
Coding and development
Solid single-editor screen; pair two for more room.
Design and photo work
IPS keeps colour steady across the panel.
Casual gaming
60Hz is fine for story and strategy games.
Films and streaming
Comfortable for streaming and catch-up.
Study and research
Big enough to read PDFs for hours without strain.
Laptop docking
Connects over HDMI — you keep the laptop charger plugged in.
Spreadsheets and finance
Workable, but you will scroll on big sheets.
Video editing
Editable, but the timeline and preview will fight for space.
Competitive gaming
Under 100Hz — buy a high-refresh screen if ranked FPS is the point.
