9. Unstable or unfocused image or trembling
Check the DVI cable is connected correctly to both the computer & the monitor.
▪
If a PC’s display mode has been changed, the monitor will need to be readjusted to comply with the
▪
new settings.
10. My monitor emits a strange smell
Most electronic devices including TVs, hi-fis etc have a tendency to emit a distinctive smell when
new. This is due to the components, particularly the printed circuit board inside, warming up. The
smell will disappear in a short time and is by no means harmful or an indication of a fault. Should the
problem continue after 72 hours of use, please switch off the monitor from the mains and contact
Hazro for further instructions.
11. Which graphics card do you recommend?
Hazro recommends you use as high-quality card as your budget will allow. As a minimum, please
ensure your graphics card supports resolutions upto 2560x1600 and has atleast one DVI port which is
specifically labelled as ‘Dual Link’
12. My monitor is displaying a ‘burnt-in’ image (also called image persistence)
Image persistence is damage caused by static (non-moving) images displayed for lengthy periods of
time (also referred to as “burn-in”). LCD panels do not suffer from permanent image persistence and the
problem is revocable. To recover from “Burn-In”, leave the panel OFF for the same period of time it took
for the image to ‘burn in’ in the first place. Burned images are preventable by utilising a moving screen
saver or power management.
13. Some RGB (Red, Blue and Green) colours are missing
If any of the red, green, or blue colours are missing, check the signal cable to make sure it is tightened
correctly. The pins in the cable could be loose and cause a bad connection.
Check video cable to ensure all pins are straight.
14. What DVI cable do I need for Hazro monitors?
Use the supplied DVI cables only. Should you order a replacement DVI cable, please ensure a “Dual Link
DVI-D” cable is ordered for the Hazro HZ30Wi.
15. How do I clean the metal housing?
Turn off the power & disconnect all signal cables before cleaning. Wipe the outer shell with a clean, soft,
lint-free cloth (use a small amount of WATER ONLY if necessary to dampen the cloth). To avoid damage
to the coating, never use alcohol, methanol, gasoline, or oil products on the outer shell.
16. How do I clean the LCD screen?
Turn off the power from the mains and disconnect all signal cables before cleaning. Wipe the screen
with a dry, clean, soft, lint-free cloth to remove dust and fingerprints. In addition to small of amounts of
clean water, a mild glass cleaner that contains no alcohol or ammonia can be used to dampen the cloth.
You must NEVER use ammonia or alcohol based cleaners as they may damage the screen and void
your warranty.
17. My monitor displays flashing lights upon shutdown of PC?
This is usually caused by a fault in the input signal cable (most likely DVI). A replacement cable
should be used in the first instance to check if the problem continues. Should this cable-swap not resolve
the issue, please contact the Hazro support team to file a Warranty claim.
18. I am unable to operate the monitor at its native resolution
Please ensure you have a graphics card that has atleast one DUAL LINK DVI connection
