HDMI connection issues:
The Ui24R requires that HDMI connected components be able to recognize and communicate with each
other.
This is referred to as the “HDMI handshake”. If the “handshake” doesn’t work, the HDCP encryption
that is imbedded in the HDMI signal is not being recognized properly by one, or more, of the connected
components.
This most often results in not being able to see anything on your monitor.
Before frustration sets in, there are some things you can do yourself if you find that your HDMI-connected
components are not communicating properly.
1. Try A Different Turn-on Sequence For Your Components:
In other words, if you have a habit of turning on your Monitpr first, then your Ui24R try the reverse
turn on sequence and see if that works.
If you find a sequence that works, remember it. Of course, make sure when everything is turned
on, and that you have selected the correct input on your monitor.
Once you have determined the best turn-on sequence - write it down for future reference.
2. Check Your Source Device’s Video Resolution Output Setting:
Ui24R output resolution is fixed at 720p check that your monitor is set to the same resolution as
well, most monitors automatically scale to the right resolution although some need manual selec-
tion.
3. Troubleshooting HDMI-to-DVI or DVI-to-HDMI Connection Problems
Another HDMI connection issue sometimes arises when it is necessary to connect an HDMI-en-
abled device to a TV or monitor that has a DVI connection, or a DVI-enabled source device to an
HDMI-equipped TV.
In this case, you need to use an HDMI-to-DVI conversion cable (HDMI on one end - DVI on other
other) or use an HDMI cable with an added HDMI-to-DVI adapter or a DVI cable with a DVI-to-
HDMI adapter. Check out examples of DVI/HDMI adapters and cables on Amazon.com
The added requirement is that the DVI-equipped device you are connecting is HDCP-enabled.
This allows the proper communication between both the HDMI and DVI devices.
Ordinarily, there should not be a problem converting HDMI to DVI, but there can be. For example,
you will find that 3D and 4K signals are not compatible. With standard 480p, 720p, or 1080p reso
-
lution video signals.
On the other hand, you can also run into a situation on older-DVI equipped TVs that even if they
are HDCP compliant, they may not have the proper firmware to recognize the identity of the HDMI
source component you are trying to connect.
An ACTIVE HDMI to DVI or HDMI to VGA adapter normally works better than a passive one.
