Hey there,


I was wondering if somebody could help me what the next thing is that I need to do to successfully reduce overscan on my 1080p TV (JVC 61FH97). I can get the resolution down to 1884x1062 using custom timings, but if I try to adjust it lower than that, the screen will no longer accept the resolution. I don't know what to do with the "SYNC WIDTH" parameters; I'm wondering if these might help, and if so, what it means to adjust them.


Any help would be greatly appreciated.


Thanks!

Richard

INITIAL TIMINGS

PowerStrip timing parameters:

1920x1080=1920,88,44,148,1080,4,5,36,148500,1


Generic timing details for 1920x1080:

HFP=88 HSW=44 HBP=148 kHz=67 VFP=4 VSW=5 VBP=36 Hz=60


VESA detailed timing details:

PClk=148500.00 H.Active=1920 H.Blank=280 H.Offset=72 HSW=44 V.Active=1080 V.Blank=45 V.Offset=4 VSW=5


Linux modeline parameters:

"1920x1080" 148.500 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync

REDUCED TIMINGS

PowerStrip timing parameters:

1884x1062=1884,106,44,166,1062,13,5,45,148500,1


Generic timing details for 1884x1062:

HFP=106 HSW=44 HBP=166 kHz=67 VFP=13 VSW=5 VBP=45 Hz=60


VESA detailed timing details:

PClk=148500.00 H.Active=1884 H.Blank=316 H.Offset=90 HSW=44 V.Active=1062 V.Blank=63 V.Offset=13 VSW=5


Linux modeline parameters:

"1884x1062" 148.500 1884 1990 2034 2200 1062 1075 1080 1125 +hsync +vsync

Hi !


You can try this :


Active H pixel 1920

total H pixel 1920+88+44+148 = 2200

H back porch pixel 148

H sync pulse width 44

H front = H total - (H syn + H back + active H) = 2200 - (44 + 148 + 1920) = 88


Active V pixel 1080

total V pixel 1080+4+5+36 = 1125

V back porch pixel 4

V sync pulse width 5

V front = V total - (V syn + V back + active V) = 1125 - (5+4+1080) = 36

Hey Alex,


Thanks for the response! As I understand it, that gives me 1920x1080 with a bunch of overscan. I'm trying to reduce the dimensions (and increase the porches appropriately) to reduce the overscan. So I've gone from 1920+88+44+148 to 1886+104+44+166 (both = 2200), and 1080+4+5+36 to 1062+13+5+45 (both = 1125). The 1886x1062 works; however, anything less than 1886x1062 doesn't. Any ideas why that would be?

Hello,

I connect ps2 to VP30 by component cable and output VP30 by hdmi cable(disable hdcp in VP30) to EZ 130. it dont works.

But i have tried this one.
I connect ps2 to VP30 and then connect it to Elgato game capture and it works fine.

I also tried these settings which are:
1.- connect ps2 to VP30 to Atlona hdmi2hdmi converter and then to EZ 130, it works fine.
2.- Connect ps2 to VP30 to DVDO iscan mini and then to EZ 130, it works but the audio is not synchronized.

But someone told me that i need to modify the vesa settings for 1080p in the VP30 and i see that there are a lot of probability to get the correct one.

So any help.
