The seven-signal monitor checklist
Use this before opening a comparison table. If a product fails one critical signal, a longer feature list will not rescue it.
Job
Name the primary device, software, games, room light, and weekly split between work and play.
Size + distance
Measure desk depth and viewing distance before choosing 24, 27, 32, or 34-inch ultrawide.
Resolution
Match pixel density to text needs and rendering load: 1080p, 1440p, 3440 × 1440, or 4K.
Motion
Choose refresh rate with realistic frame rates; look for measured response and overshoot, not a 1ms badge.
Panel behavior
Balance contrast, viewing angles, dark transitions, text rendering, brightness, and static-content risk.
Connections
Verify every mode over the exact port: HDMI, DisplayPort, USB-C video, power delivery, KVM, and console support.
Physical fit
Check stand range, VESA mount, footprint, cable exits, laptop-lid load, and return path.
Two final questions
What is the most expensive failure? A GPU mismatch, unreadable text, an unsupported laptop connection, a weak stand, OLED anxiety, or a screen that does not fit the desk?
What evidence would change the decision? A current manual, an independent measurement, a compatibility report for your exact device, or the seller’s return terms?
