Note:
1.
Show “Input Not Supported” warning message.
When Vertical Frequency is over 76Hz or under 5
6Hz, 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 Single-
Link), 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.
