How to choose a monitor
Decide the panel technology first, because it sets the character of everything you see. IPS gives accurate colour and wide viewing angles with mediocre blacks. VA gives deep blacks with slower dark transitions that can smear. OLED gives true blacks and near instant response, with a burn in risk on static interfaces and a higher price.
Resolution against size
Pixel density, not resolution, decides how sharp a screen looks. 1080p is acceptable to about 24 inches, 1440p suits 27, and 4K is what makes 32 inches and above look clean. A 32 inch 1080p panel is a large blurry panel.
Refresh rate and response time
Refresh rate is how many frames the panel can show. Response time is how fast a pixel changes. A 240Hz panel with slow transitions looks worse in motion than a well tuned 144Hz one. Quoted response times are usually a best case grey to grey figure under overdrive, so treat them as a ceiling.
Brightness and HDR
Real HDR needs sustained brightness and local dimming. A panel badged HDR400 with no dimming zones is an SDR panel accepting an HDR signal. For a bright room, sustained nits matters more than any HDR label.
Ports, and what they can carry
Check the bandwidth, not just the connector. Some panels hit their maximum refresh rate only over DisplayPort, or only with compression enabled. If you want one cable to a laptop, confirm the USB-C port carries video and enough power delivery for that machine.
Common mistakes
- Buying refresh rate a graphics card cannot feed.
- Ignoring the stand. A panel with no height adjustment will need a monitor arm, which is part of the cost.
- Assuming variable refresh rate works over every input on the panel. Often it does not.
