Possible x2 incompatibility problem

[Lake]

I just bought an OSSC.
I have a SNES (pal version) and a MegaDrive with a pal/ntsc/ntscJ mode selector.
My television is a philips model 32pfl8605h.

I read in the wiki that default line doubling is expected to work with any television,
but I was surprised to see “video format not supported” on my TV when I tried playing with
the MegaDrive in ntsc/ntscj format.

This is the format that is being displayed on the ossc:
YPrPb 262p
15.55Khz 59.36Hz

With the selector switched to PAL, the television has no problems.
The SNES also has no problems as the video format is different.

My question is: is it normal that my television doesn’t support the
supposedly universal line doubling format?

Might there be something wrong with my modded MD?

Thanks in advance.

I had a similar TV model before which would handle a modded SNES in NTSC mode no problem (59.53Hz), so maybe that’s about the limit for vertical refresh rate. I think you might have crossed the tolerance level for vertical refresh with that modded MegaDrive.

A solution would be to get a Dual Frequency Oscillator, to output correct clock speed for NTSC.

I remember encountering a Philips TV that was actually more compatible in line triple, so you should definitely give that a go too.

I’m gonna ask a very, very stupid question now but..

There’s no way to set line triple without the remote controller, right? ^^;

Right, I had forgotten about that, lol. Had noted it in my own initial report. 🙂

Yes, you need a remote to access the menu to set Lx3.
