OSSC Pro sync issue with HDFury 3 in CRT output mode

[ackmangogo]

Hi,

I’m encountering a sync issue when using the OSSC Pro in Scaler mode together with an HDFury 3.

Setup:

OSSC Pro in Scaler mode
Output connected to HDFury 3
Analog display connected to HDFury (via VGA / component)

Issue:
When selecting CRT output mode on the OSSC Pro, the display loses sync (no signal / unstable image).
However, when switching the OSSC Pro to DFP output mode, the signal is stable and works correctly through the same HDFury 3 setup.

Additional notes:

Same cables and hardware are used in both cases
Only the OSSC Pro output mode is changed
HDFury 3 DIP settings remain unchanged
Sync loss occurs immediately when switching to CRT mode

What signal are you processing through the OSSC Pro, or is it happening just with the test pattern?

Also, which CRT output mode you have selected?

From xbox360 and TV box, both tested from 480p and 720p.

Source -> ossc pro hdmi in -> hdfury3(component) -> bvm d20

A-LM output 480i and 480p works. 240p lost sync.

Scaler mode output:

DFP: 480p and 720p works.

CRT: tried 240p, 480i, 480p, lost sync.

Maybe HDFury3 does not support the CRT modes which have high horizontal rate.
