There are 4 type of bezel compensation in display
mode list. Below % is calculated by total bezel size
divided by active display area in H&V:
a. No bezel correction: no information missing
b. 3.5mm mode: H=
0.289280%
, V=
0.514177%
c. 4.9mm mode: H=
0.471163%
V=
0.837464%
d. 1.5% mode: H= 1.496090% V= 2.552533%
The actual “bezel to bezel” size to be corrected is
based on the active display width (H) and height (V)
multiple the above % value.
For example, if user uses 55” panel (1218 * 685mm
active display) and select 4.9mm bezel correction
mode, the “Bezel to Bezel” value will be
H=1218*0.471163%=5.74mm
V= 685*0.837464%=5.74mm
The actual “Active to Active” size is
H=5.74 mm+0.3mm=6.04mm
V=5.74 mm+0.3mm=6.04mm
Active to Active (Gap=0.3mm) 3.8mm
Bezel to Bezel 3.5mm
