Frequently Asked Questions - E90fmb VIEWSONIC
How should I clean the screen of my ViewSonic E90fmb?
Use a soft, dry lint-free cloth to gently wipe the screen. Avoid any liquid cleaners or harsh chemicals as they can damage the anti-glare coating. Unplug the monitor before cleaning.
Why is the image flickering on my E90fmb?
Flickering is usually caused by a low refresh rate. Set the display to at least 75Hz on the recommended resolution of 1280 x 1024. Make sure the graphics driver supports the refresh rate.
How do I adjust the brightness, contrast, and geometry?
Use the OnView controls on the front panel. Press the Menu button, navigate to the Brightness/Contrast or Geometry submenu, and adjust settings using the +/- buttons.
Can I connect this CRT monitor to a laptop?
Yes, if your laptop has a VGA output. Use the included 15-pin D-sub cable. You may need to change the display mode and set the external monitor to the recommended resolution.
What does the degauss button do?
The degauss button demagnetizes the picture tube to remove color impurities or patches caused by magnetic fields. Press it if you see distorted colors; wait a few minutes between uses.
Why does the screen show rainbow colors or purple patches?
This is due to magnetic interference, often from speakers or other electronic devices. Use the degauss function, and keep magnetic sources at least 60 cm away from the monitor.
How can I change the resolution?
Right-click the desktop and select Properties (or Display Settings), go to the Settings tab, and choose the desired resolution. The recommended resolution is 1280 x 1024 at 75Hz.
Is it safe to leave the monitor on all day?
Yes, but it is better to use the power saving mode or turn it off when not in use. CRT monitors generate heat and consume about 130W, so enabling Energy Star settings helps reduce power.
Why is there a faint buzzing noise coming from the monitor?
A subtle buzz can be caused by the high-voltage components and electromagnetic coils inside a CRT. This is normal as long as the image is stable. If the noise becomes loud or changes, check for interference or consult service.
How should I dispose of my old CRT monitor?
CRT monitors contain lead and other hazardous materials, so do not throw them in regular trash. Take it to a certified e-waste recycling center or return it through a manufacturer take-back program.
