Some intermediate devices may have compatibility issues or not support specific audio formats or video resolutions. Generally, such intermediary devices do not cause transmission issues while routing or processing audio-video signals.īut if the device is faulty or sub-par or its cable is bad, it could interrupt or degrade the incoming signal, causing signal loss, as reported by this Reddit user. Remove Any Intermediary Device in Your Setup (Receiver, HDMI Splitter, HDMI Switch, Audio Extractor, etc.)Īn intermediary device, such as an audio extractor or HDMI switch, can cause the input signal to disconnect randomly. Choose Auto Source and toggle the setting Off.īased on the model, the setting could be called “Off” or “Disable.”Īlso, if the path to access Auto Source on your Optoma projector differs from the above, refer to its user manual for the exact instructions.Press the Menu key on the projector or its remote control.If you suspect that to be the case, turn off Auto Source and choose the source manually instead. If your Optoma projector encounters signal loss, possibly the device is looking for an input source and detecting the wrong signals. In some scenarios, the feature could switch between available input sources rapidly, causing flickering, signal interruptions, or signal loss. At times, it may pick up the wrong source. Your Optoma projector prioritizes a source based on its signal strength if multiple connected devices exist.Īlthough it all sounds great on paper, and the auto feature is very convenient when connecting an input device initially, the feature doesn’t always work as per design.įor instance, it could mistakenly detect an unstable or weak signal, causing signal loss or unwarranted input source modifications. When turned on, your projector constantly scans its environment for incoming signals. The feature helps the projector automatically identify an active input source and connect to it without manual intervention. Turn off your Optoma projector’s Auto Source functionality. The soft reset will also address any HDMI handshake issues present. If some software glitches or temporary settings were causing the problem, unplugging and plugging it back again shall eliminate them. If the issue persists, connect another input device to your Optoma projector to check if the problem lies with the current source device.Īlso, do a soft reset (turn off the projector, unplug it for 30 seconds to a minute at least, plug it in again, and power on the device). To learn more, read our piece “ Why Do VGA Ports/Cables Have Screws?.” VGA connectors come with screws to lock in the connectors and help stabilize the connection. If using a VGA cable, ensure its screws are tightened. Longer lines, as a result, often struggle with higher resolutions (4K or 8K). Get a shorter cable if the existing one is relatively long (more than 25 feet).Ī longer cable means a greater likelihood of signal degradation, thanks to “attenuation” (signal strength loss). If that doesn’t change anything, check the cable length. If it’s inserted correctly at both ends, try swapping the ends. At times, the cable may not have been fully inserted. Frequent pulling on or cable movement could cause the ports to come loose. The AV Pins of Your Cable are Damaged (HDMI, VGA)Įnsure the cable (HDMI or composite) is properly plugged in at both ends.

If you own an Optoma projector and are facing the loss of signal concern, keep reading for all possible causes (related and unrelated to the projector) and the likely fixes. It could be due to the connected devices. For example, if your Optoma projector loses its input signal, don’t assume it’s the projector. Having said that, not every issue with your Optoma projector is necessarily the device’s fault. Luckily, there’s Optoma support and hordes of material online and in other places to the rescue. In other words, something could go wrong at some point in your time using the device. However, no product is foolproof, and Optoma projectors are no exception. If you’ve got an Optoma, rest assured of the quality. The company has been around since the early 2000s, making and selling projectors of all sizes, types, configurations, etc., over the years. When the discussion is about projectors and the best brands in the category, Optoma enters the chat by default.
