Camera Why Is My Camera Mirrored? Webcam Flip, Explained
July 16, 2026
By Nasir A. Awan Your camera isn't broken: video apps mirror your own preview on purpose, and everyone else sees you the right way around. Prove it in ten seconds with a snapshot of the raw feed, find the real mirror toggles in Zoom and Teams (Meet has none), fix flipped selfies, and catch the rare genuine flips from OBS and virtual cameras.
Utilities Phone Not Vibrating? Test Your Vibration Motor and Fix It
July 13, 2026By Nasir A. Awan Phone not vibrating for calls or texts? A 10-second browser check tells you whether the vibration motor still works or a setting is silencing it. Walk the Android fix ladder, the honest iPhone checklist (the browser test is Android-only), the physical causes, and sourced repair costs before replacing anything.
Utilities Laser Printer Repeating Marks: Drum, Roller or Fuser?
July 14, 2026By Nasir A. Awan Seeing the same mark at regular intervals? Print a repeating-defect ruler, measure matching marks center to center, and use color, rub-off, and internal-test clues to narrow the fault before buying a drum, toner cartridge, transfer unit, fuser, or replacement printer.
Camera How to Check Webcam Resolution (Is It Really 1080p?)
July 12, 2026By Nasir A. Awan Your webcam's real resolution is what it delivers, not what the box says. Check it in your browser in seconds, learn why "1080p" cameras send 720p (light, USB bandwidth, app defaults), why Zoom, Meet, and Teams stream below your camera's spec, and every fix in order before buying new hardware.
Mouse Mouse Spinning Out? What It Is, How to Test It, and Fixes
July 11, 2026By Nasir A. Awan Mouse spinning out in CS2 or Valorant? Sensor spin-out is a tracking-speed failure on fast flicks, not aim skill. Watch your sensor freeze mid-spin in a 60-second browser check, separate it from drift and jitter, then fix it in order: pad, lens, firmware, USB, polling, or a higher-IPS sensor.
Gaming Why the Same FOV Feels Different Across Games (HFOV vs. VFOV)
July 11, 2026By Nasir A. Awan The same FOV number can look zoomed in or wider across games because HFOV and VFOV measure different axes, while aspect ratio, 4:3 references, viewmodels, ADS, and camera behavior change the view players perceive.
Utilities Accelerometer vs Gyroscope: What's the Difference? (Test Both in Your Browser)
July 10, 2026By Nasir A. Awan The accelerometer senses linear acceleration and gravity; the gyroscope senses rotation. Learn what each phone sensor measures, test both live in your browser with a flat-table 9.8 m/s2 check and an alpha/beta/gamma rotation check, then fix broken auto-rotate and "accelerometer not working" step by step on Android and iPhone.
Display Monitor Gamma Test: Check Gamma 2.2 and Fix Washed-Out or Too-Dark Screens
July 10, 2026By Nasir A. Awan Run a monitor gamma test, read the sRGB 2.2 pattern, and fix washed-out or too-dark screens with monitor presets, OS color profiles, GPU settings, HDR checks, and room-light control.
Mouse How Does a Computer Mouse Work? Ball, Optical & Laser
July 8, 2026By Nasir A. Awan Learn how a computer mouse turns hand movement into cursor data: old ball rollers and encoder wheels, optical image sensors, laser tracking, DPI, polling rate, lift-off distance, jitter, glass-surface limits, and the browser tests that reveal how your own mouse behaves.
