An ideal solution here would be a scaler with 4:4:4 sampling, low latency and selectable flicker filter's intensity for high-res interlaced outputs. I don't know if such a device exists. Among the ones that I know, some machines from Calibre, such as the LEDView series, come closest to the ideal - but that's only judging from the declared specifications (a couple of forum members here, who owned Calibre VPs, have questioned their veracity). They're quite difficult to find though, and be aware that the only one that's
currently listed on eBay appears to
not have the selectable flicker filter.
Yes, the flicker filter option is only on the high end HQView and LEDView machines, but I don't think it works for interlaced output. (Also sold as Eiki and Optoma machines.) Kramer sells the high end model as the vp-794. AFAIK, HQView and LEDView machines are identical.
After experimenting with my machines and asking Fudoh for an expert opinion, it seems the machines sample at 4:4:4, but there is subsampling somewhere in the processing. For high resolution inputs (720p and 960p) the upscaled 1080p output is really great. 480p to 1080p is just okay, but it's better than what you get from a DVDO.
As I recall, the "flicker filter" on the Calbre Reon HQV models is actually a deinterlacing feature. On the vp-794, the flicker filter helps battle the "flickering" of bob deinterlacing. The HQView 320 (or LEDView 320) doesn't have the flicker filter. It's a nice plus, but I don't see the point. You can get bob deinterlacing from the OSSC for free. Adding the Calibre to the chain also adds 25ms of latency minimum--and most displays can give you better results than bob deinterlacing in 25ms or less. 25ms is too expensive for less flickery bob deinterlacing.
What upset me about Calibre is they advertised 4ms of latency for progressive signals. The lowest true possible latency is ~25ms. Their customer service people and one of their engineers talked to me like condescending assholes. They continue to claim that their machine can resolve a signal, scale it, and output it in 4ms--and that's complete bullshit. It can't do that--not even as a passthrough. Also, they continue to claim it's 4:4:4, when it isn't. (HDFury does the same sh*t.)
Then again, it accepts 960p from the OSSC, the scaling engine looks very good, the (high quality setting) deinterlacing is pretty good (but not fast), and 1 1/2 frames isn't bad. You can also tate your games with it--without additional lag. So, it's a potential "all in one" machine if you are okay with ~25ms of latency. Always feed 960p from the OSSC and it's very pretty.
Honestly, if they built the Calibre Reon into a 1080p display/projector and the 25ms of lag was the total processing latency, I'd be all over it. As it stands, you need to combine it with a low latency monitor.

Your post did rattle something loose in my old brain.
Now that I think about it, the Corio2 has a flicker filter option for creating and outputting interlaced signals, doesn't it? I think the Corio2 might do it.
I admit I don't use the Corio2 as an upscaler. Do you think the upscaling from 720 lines to 1080 lines good enough for OP to use the Corio2 for 1080i?
