PSP help for a total noob

[tylerfox3894]

The first option you gave me fills a lot more than the second…

[tylerfox3894]

Well it is not as sharp as i was hoping, but option 1 gives me the most screen. I would use my ps tv if nothing else but the upscaling on it looks terrible.

[tylerfox3894]

Any other insight? I never knew my tv could cause this much trouble

[eatnumber1]

I made a few edits to my last reply. Can you check that you’re using the settings from my most recent edits? Sorry for the trouble.

If so, I’m surprised that option 1 fills the screen more. Nevertheless, we’re pushing up against a hard limit of 203 offscreen lines, so if filling the screen as much as possible is your priority, then there’s not much else to be done as far as the resolution goes as long as you also want to preserve the correct aspect ratio.

Also make sure you’ve got the Video LPF and Sampling LPF settings right, and your sampling phase set right. I turn both LPFs off, and tweak the sampling phase until the image is stable.

[tylerfox3894]

How do i turn the sampling lpf off? I found the option for video lpf and turned it from auto to off

[tylerfox3894]

And yes i was using 768×432 in line 2x mode. 576×324 in 1x mode fills the screen substantially more. I do want to preserve aspect ratio

[tylerfox3894]

Wait i hadnt considered my tv’s fill settings. Im going to try that quick with 2x mode

[tylerfox3894]

Ok now i see what was going on. 768×432 does give a larger picture. But my tv can zoom further in on the 576×324 picture, and that is why it appeared larger, as well as less sharp. The 768×432 looks good for what it is but i was hoping for more screen filled. I guess i can live with the less sharp 576×324, at least for now. Any chance the ossc pro will be able to make this more possible?

[tylerfox3894]

And could messing with the sampling and lpf thing help me get the 480×272 mode working? I have no idea what either option does.

[eatnumber1]

Sorry, I meant Analog Sync LPF (that’s what I get for replying on my phone).

I realized I did the math wrong for calculating which of the options fill the screen the most.

Option 1 is a 480×272 picture in a 576×324 frame. That’s 83% full both horizontally and vertically.
Option 2 is a 960×544 picture in a 1536×864 frame. That’s 62% full both horizontally and vertically.

So yeah, it makes sense that option 1 is larger then. If your TV has zoom / fill functionality, then as you’ve mentioned, use that with line2x.

Oh one more thought, make sure that upsample2x is turned off (I think it’s always disabled with PSP mode enabled, but I forget now).

As far as OSSC Pro goes, the fundamental issue that we’re running into is that we can’t change the clock rate of the video signal. We’re playing tricks with what’s onscreen vs. off, but the clock is always 858 pixels per line * 525 lines per frame * 59.94 frames per second = 26.9 MHz (or *4 in line2x, so 107.9 MHz). With the OSSC Pro, we’ll have the flexibility to read the signal into a frame buffer and output it at a much slower clock rate (without adding lag), which would have the result of removing the large offscreen regions, which will fix your problem. So yes, OSSC Pro will fix this.

Correction: OSSC Pro can fix this in theory. I have no idea if marqs is implementing it in such a way that it will work out of the box. It may require a custom mode be added.

[tylerfox3894]

I guess my best bet is to wait for the ossc pro then. I was planning on upgrading anyway, but i can use these settings in the meantime. As for now ill be sticking with option 1. My tv doesnt have consistent zooming options and it kind of works on a per resolution basis. I can zoom in on option 2 but it does not get me anywhere near as much screen fill as option 1 does. I did have upsample2x off. I do not even know what that does honestly.

[eatnumber1]

upsample2x doubles the rate at which the analog signal is sampled. Essentially, you get “inbetween” pixels representing the analog signal at the point between two pixels. It has the effect of softening the image, which can look good for some e.g. 3d games.

I think it’s disabled for all optimized modes however, so changing it probably does nothing when the PSP mode is enabled. If your screen doesn’t flicker when toggling it, it’s doing nothing.

And could messing with the sampling and lpf thing help me get the 480×272 mode working? I have no idea what either option does.

Unlikely. If my theory about your TV only supporting 203 offscreen lines is correct, then it won’t help. Having those set wrong however can make your image blurry, hence why I thought of it when you said the image was somewhat blurry. The correct values for that depend on console, cables, ambient RF noise in your room, etc., so I can’t say what yours should be… I can only say what I do for my setup.

[tylerfox3894]

Well it isnt “blurry” per say, just not as sharp as it could be compared to 2x mode. Like taking any signal and using 2x, 3x, or 4x mode they always look noticeably sharper than passthrough mode. It all comes down to how my tv handles those signals. It is pretty bad at upscaling anything below 720p

Greetings,

I know this post was for a different setup but I do have a similar TV resolution but using a Wii though.

I have a Hisense R6 4K 65″ TV max resolution is 3840×2160 and was wondering if the these settings are correct to use with a Wii also?
Setup is: On Wii the settings are on 480P/16:9>Output to OSSC via component (HD Retrovision Wii/Wii U Premium YPbPr Component Video Cable)>Mclassic>HDMI in on TV.

Iv’e played with different setting and the Hisense can take many modes 480p, 1080p, 1440 etc. that I’ve tried but usually looks soft or blurry. I also have an Mclassic and am looking for a sharp picture? Iv’e tried all other combinations and nothing looks decent?

So are these setting below correct and the best maximum sharpest setting for a 4K to try? Or do I have it all wrong?? I’m new to all this apologies. Just want the best image and aspect ratio like the OP. I have different zoom options also but try to not use them but will if needed on the TV.

Line2x, H. Active to 960 and V.Active to 544. If yes then what are the other setting to be set as?

768×432? lineX2: ON
H. samplerate:?
H. synclen:?
H. active: 960
V. active: 544
H. backporch:?
V. backporch:?

I also ordered Hyperkin HD Cable for Wii thinking to bypass the OSSC and go to the Mclassic right to the TV for a better image? I’ve never heard anyone do that so I maybe the first?

Thank you kindly.
