It is 1/2.
The ranks total resolution of the most whole wall will be scaled original 1/2, i.e. echo effective resolution
3840 × 1080@15hz, i.e. half screen echo shows.
2) 4K optimum echo mode
If 4k shows according to 30Hz echo, then 4K resolution both of which: 3840 × 1080 with
1920×2160。
A. according to the first pattern, it is output as 3840 × 1080@30Hz
The first row zoom factor=row total resolution/3840=7680/3840=2 is (if more than 2, just
Regarding is 3 process)
First row zoom factor=row total resolution/1080=2160/1080=2 is (if more than 2, just
Regarding is 3 process)
According to the calculation that the first ranks zoom factor is maximum, because according to minimum calculation, then meeting additionally is overflow
Go out screen.
So selecting row zoom factor is 2.
B. according to the second pattern, it is output as 1920 × 2160@30Hz
Second row zoom factor=row total resolution/1920=7680/3840=4 is (if more than 4, just
Regarding is 5 process)
Secondary series zoom factor=row total resolution/2160=2160/2160=1 is (if more than 1, just
Regarding is 2 process)
According to the calculation that the second ranks zoom factor is maximum, because according to minimum calculation, then meeting additionally is overflow
Go out screen.
So selecting row zoom factor is 4.
C. optimization model is selected
The first pattern zoom factor is 2, and the second pattern is scaled 4, minimum excellent according to image scaling,
So selecting the first pattern is 4K optimum output mode.
In conjunction with information above, according to the first pattern 3840 × 1080@30Hz, then echo zoom factor is also
It is 2, but echo effective resolution is 3840 × 1080@30hz, and full frame echo shows.
