About PanelScope: Monitor Tester
PanelScope turns your iPhone into a professional controller for testing an external monitor or display. Connect a display supported by iPhone and iOS, choose a test, and send a clean full-screen signal to the external display. Controls and guidance stay on your iPhone. PANEL & COLOR • Look for dead, stuck, bright, or unusual subpixels with black, white, red, green, and blue screens. • Check uniformity, grayscale, gradients, contrast, black and white levels, saturation, and color bars. • Hide pattern names and output information when you need an unobstructed test image. GEOMETRY & SHARPNESS • Check scaling, cropping, aspect ratio, edges, fine lines, checkerboards, and sharpness. • Use native rendering and original-pixel image output where available. MOTION & FRAME RATE • Observe ghosting, smearing, judder, and dropped-frame patterns. • Use moving bars, scrolling checkerboards, a frame counter, and drop indicators. AUDIO & AV SYNC • Generate sine waves, square waves, and noise signals. • Choose frequency, channel, and level. • Use a visual sync pulse to help assess audio and video timing. PRO TOOLS • Browse a categorized library of test patterns. • Create custom RGB or HEX colors and display selected images. • Inspect render size, screen mode, color gamut, EDR headroom, and the maximum refresh rate reported by iOS. • Build automatic test sequences with a configurable interval. PanelScope generates test signals for visual inspection. It does not automatically identify defective pixels and is not a replacement for a colorimeter or professional calibration equipment. For pixel-accurate checks, a wired USB-C connection is recommended; AirPlay may introduce scaling, compression, or delay.
