Troubleshooting & Frequently Asked Questions
Do the displays have 'snow' or a lighter-image if the signal weakens?
Nope! All of our displays have pure-digital input decoders. They're not suitable for FPV displays where you want the
display to go fuzzy instead of cut out.
If you power cycle the display does it turn back automatically or does it need to be switched on each time via the
power button?
All of the displays auto-turn on when power is applied. It goes to whatever was last selected so you have to set it up
once then every time its power cycled it will come up automatically.
How come I hear a ticking noise when I shake my display?
Please note that there might be a 'rattle' when shaking this display, due a small piece of non-conductive plastic that
gets pushed into the enclosure during assembly. It's not harmful to the display or affect performance
Which displays are good for use with older arcade/computing devices with 4:3 ratio?
The RTD2660H based drivers have a 4:3 ratio mode that will squish the display down to 4:3, which some people
with older devices seem to need! We have not actually tested it but have heard reports it works well
The RTD2668 based drivers (HDMI+Audio)
say
they have a 4:3 mode but when you try to switch it over, nothing
happens to the display so we don't think it really works!
What happens if I can't output the native resolution from my device?
The HDMI drivers all have an 'EDID' that tells the computer/HDMI host what resolution it prefers (the native
resolution)
You may need to manually set this resolution on some computers, the Raspberry Pi for example does best if you
'force' it using the config.txt which is included on the page for each display
You can send a higher or lower resolution image and the HDMI driver will automatically scale it down or up.
However it wont look as good because of the scaling! For the best look, especially crisp text, use the native rez!
How do I set the resolution in the monitor/display?
You can't! Resolution for HDMI/VGA/Composite is always set by the video emitter. If the resolution isn't right on the
monitor, go to your computer/console system prefs!
Eeek I set the RTD2660H-based driver into a bad mode and now I can't see anything!
First, make sure it is powered and connect HDMI to your computer, make sure you see the LED is green which
means it is getting good HDMI signal! press S5 and wait 5 seconds after pressing, to switch from HDMI to VGA to
AV1 to AV2 and back to HDMI
then press these buttons, wait about 1 second between presses!
S2 S3 S3 S2 S2 S3 S2
where S1 is the switch closest to the green LED, S5 is the farthest from the green LED
I'm getting vertical line(s) when the display is connected to a Raspberry Pi.
Use raspi-config to force audio out the 3.5mm audio jack (rather than HDMI or auto).
