3.9 VGA/HDMI Configuration on RSB-4210

In this section, we will introduce how to configure VGA/HDMI on RSB-4210. As

depicted in Figure 3-12, IC CH7033B on RSB-410 board will be used for transferring

TTL signal to VGA/HDMI output.

Figure 3.12 Block diagram of video configuration on RSB-4210

There are two output modes for VGA/HDMI signals on RSB-4210 as shown below:

 Auto mode: CH7033B controls output timing.

 Bypass mode: CPU Freescale i.MX53 controls output timing.

The following sections will introduce each of the output modes in detail.

3.9.1 Auto Mode

Auto mode is the default setting of RSB-4210 VGA/HDMI output. In auto mode, the

display interface 0 signal (DI0) has already been modified to output 720P60 (1280 x

720 @ 60) in advance. As illustrated in Table 3-13, there are three default input res-

olution timing settings for HDMI and one for VGA for reference.

When connecting a HDMI panel with the board, the output resolution of the panel will

be adjusted to the most optimal default setting automatically by CH7033B. (For

example, if the panel supports 1080P as its max resolution, CH7033B will detect and

adjust its output resolution to 1080P after connecting the panel with RSB-4210.)

When connecting a VGA panel with the board, the output resolution of the panel will

be adjusted to 1024x768 output resolution no matter what the max resolution your

VGA panel supports.

3.9.2 Bypass Mode

Bypass mode is an output alternative that the output resolution will be determined by

default timing settings of your panel. There are 44 built-in timings provided by Advan-

tech on RSB-4210, you can choose either one of them to match the timing setting of

Note! Several resolution settings of your panel might cause the screen output

to be partially cut. This is due to panel compatibility limitations. To solve

this issue, it is necessary to fine tune the timing for specific resolution

settings of your panel.
