OSSC Pro Pure LM 240×360 proc output issue

[mahi1995]

I have a question regarding the output when using gbihf-ossc in OSSC Pro’s Pure Line Multiplier mode.

I’m using a GCVideo-DVI adapter to connect the HDMI signal from my GameCube to the HDMI input of the OSSC Pro.
The output of gbihf-ossc is 960×360.
When I set OSSC Pro to Pure Line Multiplier mode and select Line2x 240×360 or Line3x 240×360 under the 384p/400p proc, the output becomes incorrect.

Using Line2x 240×360 results in an output of 1920×1440. The status screen shows x4.
Using Line3x 240×360 results in an output of 2560×1080. However, this signal is treated as 2560×575 by the capture card and monitor. The status screen shows x5.

I tried setting the Pixel Decimation to 4 and changing the input to 240×360, but the result was the same.

If the OSSC Pro’s Pure Line Multiplier behaves the same as the OSSC Classic, I would expect the output to be 720p or 1080p, but that’s not the case.

I noticed a difference when comparing the source code of OSSC Pro and OSSC Classic v0.90.

OSSC Pro:

            case GROUP_384P:
                //fixed Line2x/3x mode for 240x360p/400p
                valid_lm[2] = MODE_L3_GEN_16_9;
                valid_lm[3] = MODE_L2_240x360;
                valid_lm[4] = MODE_L3_240x360;

OSSC Classic v0.90:

            case GROUP_384P:
                //fixed Line2x/3x mode for 240x360p
                valid_lm[2] = MODE_L2_240x360;
                valid_lm[3] = MODE_L3_240x360;
                valid_lm[4] = MODE_L3_GEN_16_9;

Is this related?
I don’t understand programming.
Sorry if it’s unrelated.
