1. Show “Input Not Supported” warning message.
When Vertical Frequency is over 76Hz or under 56Hz, the display is Black and showing “Input Not

Supported” warning message. (Some video timings are except for PAL, 50Hz signals.)

2. If Hf /Vf is set in the range of 31KHz~83KHz and 56Hz ~76Hz (not including some video timing), and
Pixel Clock is set in the range of 25.175MHz~173MHz(DVI and HDMI input port 165MHz for Single­Link), but is not the above Resolution, then it will display the nearest mode.

3. When digital input 1680x1050@75Hz and 1920x1080@60Hz_CVT, because of TMDS Pixel Clock is
setting in the range of 25MHz~165MHz, the source may use Dual-Link signal to transmit the timing.
This model can only support Single-Link to receive the information of half-of- Dual-Link, the display
may be abnormal.

*All spec. of monitor need to warm up at least 1hr.

6.2 Circuit Operation Theory
I. Introduction:

G225HQ is a 21.5 inch and 24bits color TFT LCD monitor, which can support the resolution up to 1920x1080. It
has VGA input and compliant with VESA specification to offer a smart power management. The monitor has
DDC/CI function to make the monitor communicate with PC by Acer ADM DDC/CI software, and also it has
ACM function to let the monitor contrast ratio up to 50000:1. It also offers OSD Menu for users to control the
adjustable items and get some information about this monitor.

II. Block diagram

G225HQ consists of a main body and a stand (base). The main body contains a AUO/LGD TFT
LCD module with 4 CCFL lamps, a power board (includes AC/DC、 DC/DC、 inverter and

panel power source), a control board and an interface board. The block diagram is shown as
below.

III. Circuit Implementations:

A.) THE MAIN BODY:
A-1.) Interface board block diagram:

(a) Circuit operations:

The scaling IC has OSD and auto detecting input timing functions. OSD offers adjustable functions to the end­users. Auto detecting timing function can detect change modes. It outputs the digital R-G-B data, pixel clock
and control signal to TCON of the LCD module. A MCU, build in scaling IC (Realtek2545LH), is responsible for
the system processing. There are two external storing units, one is 24C16 to store the OSD function data and
user preset timings.

(b) IC introduction:

1.) Realtek2555LH SCALER IC:
Realtek2555LH series products are all-in-one LCD monitor controller with analog (RGB), DVI and video inputs,
supporting 1920x1080@60Hz ,and integrate Realtek high performance ADC,scaling engine,LVDS Tx,and so
on.Moreover,all products are pin compatible in QFN 48-pin package to save cost and make the design easier.
The RTD also includes an ITU656 video format input port with color space converter that makes it an attractive
solution for low cost MFM and TV applications. The output section contains a 24-bit TTL output interface and a
channel LVDS transmitter for direct interfacing of commercially available LVDS LCD panel modules. In addition,

control features.

2.) EEPROM:
We use 24C16 EEPROM to store monitor user data and user preset timings. There are 16 user timing modes
are automatically saved in it. Each timing mode is allocated with 22 bytes of memory space for information such
as Sync frequencies, polarities… etc. PC can access the EEPROM data indirectly through the SDA and SCL
channels of DVI and D-sub (IIC communication). The digital and analog DDC data are stored in two 24C02s
EEPROM.
