Troubleshooting

Why are there thick black borders around my video?
Most HDMI displays automatically scale video to fill the screen enabling PAL or NTSC video
to automatically scale and fill a high definition display so you should not encounter thick black
borders around your video.
By contrast, DVI and DisplayPort displays rarely provide scaling. HDLink Utility provides an
option named Scale video to fill larger display. This option enables current HDLink models to
scale smaller video formats to fill larger DVI and DisplayPort displays and avoid thick black
borders around the video.
HDLink Settings can scale video to eliminate black borders
and display SD video in a traditional aspect ratio
Why do circles appear elliptical or egg-shaped via HDLink in standard definition?
HDTV uses square pixels for display as does your DVI-D/DisplayPort based computer monitor
or HDMI display. SDTV uses rectangular pixels for display which is different to your computer
monitor. When HDLink is used to view standard definition video, and is set to scale video as
1:1 direct pixel for pixel, circles will display egg-shaped.
If you want the standard definition picture to look as it would on an old CRT display, launch the
HDLink Utility and select the 4:3 Aspect ratio scaling option for standard definition video. This
scaling option will scale the standard definition video to make it appear normal on an LCD
display and circles will look like circles.
HD720p50 support
All models of HDLink support the HD720p50 standard. However there are very few DVI-D or
DisplayPort monitors which support this standard. Most new HDMI-based monitors and TVs
purchased in PAL countries now include 720p50 support and should work well with
any HDLink.
