OSSC PRO 240p 120Hz on a VGA CRT Monitor

[MarcoFranco_LA]

Sorry for if I’m asking something that may be self explanatory
I have OSSC Pro with NO extras…the Extra AV output is on its way to be delivered

What I’m trying to accomplish is the following:
Scenario: Genesis system>>>Scart cable into OSSC Pro THEN OSSC Pro Output 240p 120Hz Via HDMI>>>DAC(HDMI2VGA)>>>VGA CRT PC Monitor

I can do this with Mister and the look is beautiful(very close to PVM/BVM) great for playing games on CRT PC monitor but I don’t know to do it with OSSC Pro I heard the DEXX can do it.

You need to use the Scaler opt->Framelock->Off (120Hz). Note this will introduce a little lag, but you should have a very low latency setup still with a CRT.

Thank you!!! I was able to figure it out over the weekend, took a few hours lol my Extra AV output is arriving TODAY!!…

@marqs YOU are amazing!! thank you for designing this amazing pieces of tech! I’m going to order a 2nd unit so I have one in living room and one bedroom!…

MarcoRetro should make a follow up on this!

I am playing my GBAHD on a CRT TV(240p 60hz)  and on VGA PC Monitor(240p 120hz)…same with my switch, Xbox One etc!!

@Marqs if you were to make “OSSC Pro Complete Edition”, Please integrate the Extra AV OUT board AND Legacy IN Board in ONE package and I’ll gladly pay $499.99…finally ONE down scaler to RULE THEM ALL…

PS. if anyone wants to buys 3-RetroTink5X from me let me know lol

With 50/60Hz sources it’s also possible to use Framelock on (2x) mode for minimal latency at 100/120Hz output.

Having both Extra Av Out and Legacy AV In functionality by default would require FPGA with larger pin count, especially if expansion port would need to be also preserved. I’m afraid there’s not enough people interested in this kind of ‘deluxe’ edition (which would also require PCB and case redesign) to make it feasible from cost perspective.
