General Questions
Why does it have a image residue on a MAXHUB interactive flat panel?
The image residue phenomenon, also known as “screen burn-in”, “image burn-in”, “ghost image”, “ghosting”, “screen burn” , etc., is normal during displaying stationery image for extended period of time. In order to help maintain the best performance of the panel, we highly recommend you to set up the screen saver or avoid displaying stationery image for over 1 hour. In order to remove the burnt-in image, you can try displaying dynamic contents for a while or cooling down the device and rebooting it.
Lifespan of the device
Lifespan of devices vary depending on their design. The theoretical lifespan for the device ranges from 30,000-50,000 hours (Please refer to the product spec for further details). With a daily average operating time around 8 hours, the lifespan of the device could be anything between 6 to 8 years.
In the real circumstances though, the actually lifespan may be affected by multiple factors and in rare cases the actual lifespan may fall well below 30,000 hours. However, in those circumstances you may request technical assistance and see whether or not the warranty terms is applicable.
Which kind of screen do you use for your product?
MAXHUB uses different kinds of LCD from LG, AUO, SHARP etc.
How long is your product warranty? How to claim a breach of warranty?
The warranty terms vary from your purchase terms. An extended warranty may have been purchased already. Please contact your supplier for further details about your warranty terms and if applicable, file your claims to them.
The device is heavy. Is it safe to hang on the wall like this?
Hanging bracket for MAXHUB has been tested in various settings. The bracket and the wall mount are both robust and reliable.
But please make sure the wall is strong enough to hold the device and the installation should be in accordance with our official setup guidance. Our trusted resellers have been properly informed of those protocols and professionally trained. We have not received any report of accidents about mounting yet.
However, it is recommended that you inform your supplier in detail the status of the wall as a safety precaution.
Why the new MAXHUB has dark (or bright) points on the screen?
Those point(s), often displaying constantly in black or white is(are) called defective pixel(s). In LCD manufacture, it is common for a display to be manufactured that has a number of pixels defects. Based on ISO13406-2, LCD displays are categorised into four classes. Our LCD panels lie in Class II, whereby a number of defective pixels is generally accepted.
Where can I use the electromagnetic stylus (pen)?
The electromagnetic stylus is compatible with MAXHUB ultimate series interactive flat panels.
Where do I keep the styli (pens)?
In order not to lose the styli, we strongly advise you to develop a habit of placing the styli on the pen rest or pen box once you complete your session with MAXHUB interactive flat panels. Generally there are two kinds of styli:
For ordinary styli that come with the standard series interactive flat panels, you can put them on the magnetic pen rests.
For electromagnetic styli that come with the ultimate series interactive flat panels, you can put them in the pen box (sold separately).
Why do the cameras on MAXHUB keep switching automatically?
Congratulations on unlocking a new hidden feature for MAXHUB ultimate series interactive flat panels.
Once the MAXHUB smart camera is selected for your teleconference app or camera app. It may switch according to the speaker’s location. In order not to obstruct the camera on the left bezel and right bezel. A smart switch algorithm will help MAXHUB use the camera on the top along with the camera from the OPPOSITE direction to the speaker so as to not let the speaker obstruct the camera when standing close by. This could be disabled though by selecting one of the three cameras on top, left and right sides, in which case the cameras would not automatically switch again.
Does a MAXHUB interactive flat panel have a microphone?
Sure it does. Actually it has SIX. The microphones are not only for voice collection but also for voice enhancement, noise cancellation and the smart switch for the cameras on ultimate series.
Why is the brightness of the screen constantly changing when I am using the MAXHUB interactive flat panel?
On a MAXHUB interactive flat panel, the brightness would change automatically according to the lighting conditions of your room so as to achieve optimal display effect. In case you want the device to keep a constant level of brightness, you can turn off the auto-adjustment in settings.
Why does my MAXHUB interactive flat panel switch off automatically?
Don’t worry. In those circumstances only the display is turned off. It is actually running in stand-by mode. In order to save the energy and extend the lifespan of the device, a MAXHUB interactive flat panel will automatically turn off its display once left idle. You can wake up the display by pressing on the power button or tapping on the screen.
How do I connect MAXHUB with external cameras or microphones?
Usually we recommend you connect your external speakerphones and/or cameras with USB cable(s) with the PC module inserted to a MAXHUB interactive flat panel. For most of the trusted brands in the market, their cameras or speakerphones work perfectly well on MAXHUB. But in some rare cases, due to the lousy cable quality or the external devices being in poor condition, they may not work as they were supposed to.
Besides, you may find the built-in cameras and microphones on MAXHUB interactive flat panels are brilliant as well. Give it a shot!
Whiteboard & Writing
Why did the strokes appear to be discontinuous on the panel when I was writing?
MAXHUB is supposed to write smoothly and responsively with touch inputs. Please contact us if your problem still remains after completing following steps:
Clear up the screen if there are any dust, water drops, cobwebs etc;
Try drawing circular lines along the edges of the screen continuously;
See if your stroke stopped unexpectedly during the process.
Let us know if the problem stays unresolved.
Why I cannot write continuously with my finger on MAXHUB ultimate series?
Uh huh. Actually that is because you have been writing with your FINGERNAIL. Due to the PCAP touch technology on MAXHUB ultimate series, fingernails don’t have capacity big enough to be detected (just like on a mobile phone). Instead, we recommend you touch the panel with the skin on your finger.
Why the smart pen (stylus) cannot write on the MAXHUB ultimate series interactive flat panel?
MAXHUB ultimates series interactive flat panels use PCAP and EMR touch technology. If you are using the stylus (pen) that come with a MAXHUB ultimate series interactive flat panel, check if the battery has been depleted. Replace the battery when necessary. If the problem still remains, contact our technical support. If you are using a third party stylus (pen), we recommend you check the compatibility with the manufacturer.
Does a MAXHUB interactive flat panel support multiple touch points?
Yes. Both standard and ultimate series feature multiple touch points.
However, in the built-in whiteboard, you can write with one finger only. Multi-finger touch is designed for gesture control like zooming and dragging. On MAXHUB ultimate series interactive flat panels though, you can write in the built-in whiteboard with two EMR styli (electromagnetic pens) at the same time, provided that the two styli are in different colours (colour of the rings in the middle of the pens being different).
In Windows Paint and other whiteboard application though, you may achieve ten points writing at the same time.
What if I cannot write with two styli at the same time?
Make sure you are writing in the built-in whiteboard on a MAXHUB ultimate series flat panel. The two styli should be in different colours (one of the ring is silver, the other in black). Check if both the styli have enough battery, replace the battery if necessary. If the problem stays unresolved, try restarting the whiteboard app or rebooting the device.
Why can I write with only one finger?
MAXHUB is dedicated to simplify your board writing. Multi-finger touch is designed for gesture control like zooming and dragging. You can install other whiteboard applications on a MAXHUB interactive flat panel to allow multi-finger writing.
