TechCompare's display and monitor tools help you make sense of screen specifications before you commit to a purchase. Compare a 27-inch 1440p panel against a 32-inch 4K side-by-side, check whether your HDMI 2.1 cable can actually carry 4K at 144Hz, or preview how an 1800R curve feels compared to a flat panel at your desk depth.
Use this collection when shopping for a monitor, TV, laptop, or phone. Pair the PPI calculator with the screen size comparison to judge sharpness at real viewing distances, then run the display bandwidth calculator to confirm your cable and GPU can drive the mode. Every tool runs in your browser, no accounts, no uploads.
Frequently asked questions
Which display tool should I use to pick a monitor?
Start with the Screen Size Comparison to judge physical dimensions, then the PPI & Retina Calculator to check pixel density at your viewing distance. Once you've settled on a resolution and refresh rate, use the Display Bandwidth Calculator to confirm your cable and GPU can actually drive it.
How do I compare two monitors of different sizes and resolutions?
Open the Screen Size Comparison to see the physical footprint side-by-side, then the PPI Calculator's compare mode to see how pixel density differs. Together they answer the two questions that matter most: will it fit on my desk, and will it look sharper than what I already have.
What's the difference between refresh rate and frame rate?
Refresh rate is how many times per second the monitor redraws the screen, measured in Hz. Frame rate is how many frames your GPU produces per second, measured in FPS. The FPS Visualizer shows the perceptible smoothness difference; the Bandwidth Calculator shows whether your cable supports the refresh rate you want.
Do I need a curved monitor?
Curved monitors matter most at 32 inches and up at close viewing distances, where the curve keeps the edges of the screen at a similar distance from your eyes. Use the Curved Monitor Visualizer to see how a 1000R, 1500R, or 1800R curve actually looks at your desk depth before committing.
Are these monitor calculators free?
Yes. Every tool in this collection is free to use, runs entirely in your browser, and never uploads your data. There are no accounts, no trials, and no paid tiers.
