Why is My Projector Purple?

Why does my projector have a purple tint? This question is asked by projector users on different forums, so, we decided to answer.

Not always the problem is in the projector itself, sometimes it is the projector screen or the image coming from the computer.

Open a projector menu using the remote, if it also appears to be discolored, it could result from the improper connection.

To check it, remove the VGA cable, making the projector output a no signal screen. When the no signal image appears discolored, the problem is likely in the projector.

The purple color discoloration happens because of the following reasons.

Improper Connection

Sometimes the cables are not securely connected which results in discoloration. Faulty cables need to be checked as well and replaced.

When using the HDMI to VGA adapter, make sure that the HDMI connector is properly connected to the ScreenBeam receiver.

The VGA connector should also be securely linked to the VGA cable.

While checking the connection, also look for any faulty cables and replace them with new ones if you find any.

Purple tinge or tint can result from an improper or loose connection when using the HDMI-to-VGA adapter.

Wrong Type of Incoming Signal

Purple hues result from the wrong type of incoming signal setting. When the projector is set for the wrong incoming signal a purple tint starts to appear on the screen.

By the wrong type of input signal, it means when the projector is in component video or YPbPr mode whereas the input signal is analog RGB signal.

This happens when the RGB color space is sent and the projector changes it to Y, R-y, B-y components.

It may sound like a complicated problem but can be easily fixed by changing the settings.

Ways to Fix Purple Tint

Most of the time, these problems can be easily fixed without any help from the handyman. With these easy fixes, the projector can no longer be discolored.

Secure Connection

While utilizing ng HDMI-to-VGA adapter, make sure the HDMI connector is properly connected to the receiver. Also, check the connection of the VGA cable to the adapter.

Change Input Signal Setting

Change the input signal setting to remove the purple tint and prevent a future incoming signal mismatch. For this, modify the Projector’s Signal Input to either “Auto” or “Analog RGB”.

Rectifying the projector input signal optimizes the image quality for any input signal. Go to the projector signal menu to change input signal settings.


Projector discoloration ruins the viewing experience and causes eye strain and headache. When the project begins to show purple hues, the first step is to identify the cause and then look for the appropriate solution. It happens due to multiple reasons, therefore, better to diagnose the problem before treating it with the relevant cure.
