Practical display guides
What are you trying to finish?
Pick the job in front of you. Each guide explains the background, links the screen tests that help, and gives concrete settings and steps.
Try a comparison before naming a fault
- Are the steps already in the image? Change the number of encoded gray values and compare the same downloadable PNG in two viewers.
- Why does a corner look different in a photo? Separate room light, viewing position, picture settings, and camera exposure with one-variable comparisons.
- Will the screen fit your viewing position? Compare screen width, a chosen viewing angle, and the distance available at your desk.
Choose a display guide
A display just arrived
Run one clean inspection
Prepare the setup, check fixed defects and large areas, compare motion, then save only repeatable findings.
One point never changes
Prove what the camera can show
Rule out dust and image content, photograph the physical location, and find the seller or manufacturer policy that applies.
Games tear, stutter, trail, or look wrong
Change the setting tied to the symptom
Compare two 60 fps timelines, separate delivery gaps from trails, and choose the Windows HDR control for desktop brightness or game clipping.
Letters look soft or have colored edges
Find what changes when text looks blurry
Compare live letters with a deliberately enlarged 120 × 40 source image. Then follow the file, app, resolution, or text-tuner branch.
You are about to buy
Fill out the purchase worksheet
Write down sources, desk limits, scaling, connection requirements, support terms, and the arrival-day inspection.
The product page is a wall of numbers
Work through the specification numbers
Calculate QHD/UHD workspace at different scales, convert refresh rate into an interval, and decode the brightness conditions behind HDR 600.
IPS, VA, OLED, or Mini-LED?
Compare panel types
How each technology makes an image, which artifacts it tends to show, and which one suits office work, color work, gaming, and films.
Stuck at 60 Hz or no signal
Pick the right connection and cable
HDMI, DisplayPort, and USB-C bandwidth, cable labels, adapters, and fixes for 60 Hz limits, dropouts, and washed-out color.
Colors look off
Calibrate brightness, gamma, and white
What you can set by eye with test patterns and built-in tools, why wide-gamut screens oversaturate, and when a colorimeter is worth it.
