DLPC7540EVM: About RGB enable signal delay

Hello Sasaoka-san,

When you say

Also, is it possible to delay the rising edge of this red enable signal?

 do you mean to slow the slew rate (V / second) or change when the edge is rising?

Aaron

Hello Mr. Aaron ,

This does not mean slowing down the slew rate, but rather changing the timing at which the edges rise.

Could you delay the edge timing of the red enable signal?

Best regards,

Sasaoka 

I will send you reference materials.

Hello Sasaoka-san,

Can you please check what the refresh rate is selected from the PC, i.e. 60Hz or 240Hz? Can you see any change if you select different refresh rate? 

When you said that the red enable signal is rising up just a little earlier, how do you measure it and what's the time interval?

Regards,

Lori 

Hello Mr. Lori

We evaluated at 240Hz.

Red ghosts are displayed, so we are investigating the cause.

We think timing is one of the causes. We are also investigating the cause.

If there is no way to adjust it, we will think of another way.

Best regards,

Sasaoka
