Is it possible to downscale 1600x1200 to 1080p ?

yes, you can do that. Not sure if it makes much of a difference to upscaled 4x though. Should be pretty close with a good scaler like the 301.

Hey ZellSF,

I'm writing this message in hopes to get some advice about my PSP to Monitor set up after reading your post (below).

What I'm wanting to do is get a full screen good quality image of my PSP on my monitor. From looking at your post, it seems I can do PSP>OSSC (480px2)>DVDO VP50. I've been offered a VP50 for next to nothing and not sure if this set up will work. Is this what you did?

Also, you are using the VP50 not VP50 Pro? does the DVDO VP50 take the 960p (480x2) from the OSSC with no problems? As its not a supported resolution in the manual.

"They don't. 480pX2 doesn't work on a VP50. 480iX3 and 480iX4 doesn't work on a VP50." You also said this in the previous page (133) so I'm a little confused :oops:

I hope you can give me some help

Many thanks

Will

480px2 works on the Edge, but it looks very oversharpened with lots of saw-tooth edges.

You can get 480px2 working on the 50 Pro for the PSP by playing around a bit:-

http://junkerhq.net/xrgb/index.php?titl ... n_Portable

Oh right, I did read that then forgot all about it. Doesn't help with other 480p consoles, but if anyone's wondering how it looks:

PSP3000 + OSSC + DVDO VP50
PSP3000 + OSSC 480pX2 + DVDO VP50
PSP3000 + OSSC + XRGB-mini in VIDEO mode SHARPNESS 1
PSP3000 + OSSC + XRGB-mini in GAME mode SHARPNESS 1
PSP3000 + OSSC + XRGB-mini H_SCALER 4, V_SCALER 6, SHARPNESS 0
PSP3000 + OSSC 480pX2 + XRGB-mini in GAME mode

That was annoying to set up (adjust five different settings on the OSSC, four on the DVDO VP50). I think both 480pX2 captures look fairly identical outside of color, brightness and zoom settings (captures are more to illustrate sharpness).

Um, not sure why you're confused, are you not reading things in order? Order of events:

1) I said 480pX2 doesn't work.
2) BuckoA51 said "it does work for the PSP, here are the settings".
3) I posted some screenshots of it working on the PSP.

Those screenshots are what they are labelled as, so PSP 3000 to OSSC outputting at 480pX2 to DVDO VP50 (not Pro).

Other than having to set up the OSSC as linked in what you quoted, and remembering it is a different resolution (and the VP50 likes saving some compatibility options per resolution, that might need to be changed again) there were no problems.

Well there's also the VX3276-mhd-2 which is a variant of the same, only with a slim bezel (warning: more prone to backlight bleed), and an additional input (DP) which can be convenient since the VX3211-mh only has one digital input (HDMI)


I managed to find one of these (mine says VX3276-mhd and not VX3276-mhd-2), not sure if they changed their manufacturing, but it looks like my panel has almost 0 back-light bleed. Maybe I just got lucky?

What do you mean? This is the best I've seen PSP graphics looking on a display other than its own LCD screen.

The scanlines, not a fan. Is that the nature of the PSTV, or do you have them enabled on the OSSC?

Those are just 480p scanlines, every modern PC CRT will show them in 480p sources. Since the PSP has such low resolution, it's better to just passthrough to the display instead of trying to scale it. And PC CRTs are the best when it comes to dealing with low resolutions.

The PSTV was made in the HDMI era, so I use HDMI directly to my switch. I should have read earlier where you said you were going to a monitor. Different issue.
