Question 9

How does the OLED protection feature work?

Accepted Answer

Our OLED protection prevents burn-in by using dynamic pixel shifting. A subtle 10×10 white pixel grid slowly moves across the screen, ensuring no pixel stays in the same state too long. Essential for OLED devices like iPhone 12+, Samsung Galaxy phones, OLED monitors, and OLED TVs during sessions longer than 15 minutes.

Question 10

Can I download black screen images in different resolutions?

Accepted Answer

Yes! We offer free downloads in 480p, 720p, 1080p, 1440p, and 4K. Click 'Download', select your resolution, and get instant PNG files with lossless quality. File sizes are tiny (under 50KB even for 4K). All downloads are royalty-free for commercial use.

Question 11

How do the timer and auto-exit features work?

Accepted Answer

Two timer types: Display Timer (duration for current color) and Exit Timer (auto-exit fullscreen). Use for Pomodoro sessions (25min focus), screen breaks (hourly reminders), display testing (color rotation), or sleep routines. Preferences are saved in browser storage.

Question 12

What is the difference between black screen and other color screens?

Accepted Answer

Black screens (RGB 0,0,0) test dark uniformity, backlight bleed, stuck pixels, OLED power saving, and reduce eye strain. White screens (RGB 255,255,255) detect dead pixels and test brightness. Primary colors (R,G,B) test individual sub-pixels. Each color serves specific display testing purposes.

Question 13

How do I use the custom color picker?

Accepted Answer

In fullscreen mode, access settings to use the custom color picker. Three input methods: visual spectrum selector, hex code entry (#FF5733), or RGB sliders (0-255). All sync in real-time. Perfect for brand color matching, gamut testing, or custom ambient lighting.

Question 14

Can I use keyboard shortcuts to control the tool?

Accepted Answer

Yes! F11/F (fullscreen), Esc (exit), Spacebar (show/hide controls), 1-9 (switch colors), Arrow keys (cycle colors), T (timer), D (download), O (OLED protection), C (custom color), H (help). Works in windowed and fullscreen modes.

Question 15

Does this work on dual or multiple monitor setups?

Accepted Answer

Yes! Open our tool in multiple browser windows and fullscreen each on different monitors. Windows: use Win+P for projection modes. macOS: enable 'separate Spaces' then fullscreen on each monitor. Advanced: use Chrome kiosk mode for borderless fullscreen.

Question 16

How accurate are the colors displayed?

Accepted Answer

We send mathematically perfect RGB values (black=0,0,0, white=255,255,255). Perceived accuracy depends on your display's calibration. For professional color-critical work, calibrate with a hardware colorimeter like X-Rite i1Display or Datacolor SpyderX.

Question 17

Can I use this tool for OLED burn-in testing?

Accepted Answer

Absolutely! Display our white screen in fullscreen to check for darker ghost images of static content. For prevention: enable OLED protection, avoid static elements, rotate colors every 10-15 minutes. Modern OLEDs have better longevity but burn-in is still a risk.

Question 18

How can photographers use the white screen for lighting?

Accepted Answer

Use white screen on laptops/tablets at 100% brightness as portrait fill light (position 2-3 feet from subject). Great for product photography, macro work, and as background lights. Benefits: free, portable, adjustable, no heat, silent. OLED screens provide brightest output.

Question 19

How do I use the black screen for productivity and focus?

Accepted Answer

Set 25-minute timer, enter fullscreen to eliminate all distractions for Pomodoro deep work. Creates digital boundary preventing multitasking. Also useful for Zoom calls (hide video feeds), writing (eliminate distractions), and screen time wind-down before bed.

Question 20

Can this tool help with eye strain and screen fatigue?

Accepted Answer

Yes! Use with 20-20-20 rule: every 20 minutes, trigger black screen, look 20 feet away for 20 seconds. Black screens emit minimal light, allowing eyes to rest. Reduces blue light exposure, prevents accommodation stress, helps with migraines.

Question 21

How is this useful for video editing and content creation?

Accepted Answer

Download 4K black screens for fade-to-black transitions in Premiere/Final Cut. Use as color grading reference, timeline gap filler, or YouTube stream intermission backgrounds. Create high-contrast thumbnails, test overlays for legibility. All royalty-free.

Question 22

Can I use this tool to test my TV or gaming monitor?

Accepted Answer

Absolutely! Test dead pixels (white→black screen), backlight bleed (black in dark at 100%), uniformity (gray screen), color gamut (all colors), OLED burn-in (white shows ghosts). For gaming: verify G-Sync/FreeSync, refresh rate, response time. Test within return window!

Question 23

Is this tool helpful for testing stuck or dead pixels?

Accepted Answer

Very effective! White screen shows dead pixels (black dots), black screen shows stuck pixels (colored dots). Cycle through R,G,B to detect all types. Try rapid color cycling (1-sec intervals, 30+ min) to unstick pixels. Most manufacturers allow 0-3 dead pixels before replacement.

Question 24

How can I use this tool for presentations or teaching?

Accepted Answer

Use black screens for dramatic pauses, eliminate desktop distractions before screen sharing, create audience focus breaks. For vision science: demonstrate contrast/pupil dilation. For photography classes: show screen-as-light technique. Effective attention-grabbing tool.

Question 25

Can this tool be used in retail stores or for digital signage?

Accepted Answer

Yes! After-hours display management (prevent OLED burn-in on 24/7 displays), test new displays before installation, professional transition screens during updates. No installation, works on locked kiosks, zero licensing, lightweight. Used as backup signage if primary content fails.
