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nd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rst,thenyourUi24Rtrythereverse

turn on sequence and see if that works.

Ifyound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xed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nd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rmware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.
