VGA Voltage level

Question

Hi~

I would like to know VGA Voltage level.

(at VGA-HS, VGA-VS, I2C SDA, I2C SCL)

In case of ZED, it is designed by 3.3V level.

(at VGA-HS, VGA-VS)

Is it generally 3.3V level or 5V level?

(at VGA-HS, VGA-VS, I2C SDA, I2C SCL)

Thanks you.

I do not see any I2C SDA or SCL related to VGA on ZedBoard.

Regarding the VGA syncs, I read that these are 5V TTL signals. However, as long as the Voh > 2.7V, the voltage level is acceptable.

Regarding the color signals themselves, they have a 1.0V maximum.
