Ok heres what I have a Sony CRT HDTV Widescreen 30 inch kv-30hs420 and Supposely it does 480i, 480p, and 1080i, I heard these crt tv's dont do 720p. Ok I have a ps3 60gig connected via hdmi running at 1080i.

The issue is on some ps3 demos and the full game of uncharted and some ps2 games i have, what I see is I beleive its called combing and or interlacing artifacts. When this happens is when moving the camera/screen left and right (Horizontaly) I see still images ingame like a rock, tree, car, etc get out of focus, shimmering, combing, fuzzy, jitter, vibrate, shake, I say all those words i;m trying to describe best I can.

Quickly thinking here ps3 games that have this is: Resistance fall of man, folklore, dirt, uncharted full game and demo, Motorstorm, heavenly sword, nhl 08, full auto 2, virtual tennis 3, timeshift etc.

ps2 games that i have do this are: code veronica, metal gear snake eater, hitman 2, devil maycry 1 etc.

But theres some games that are smooth no issues like ps3: ninja gaiden sigma, call of duty 4, ridge racer 7, rachet clank, etc.

Ps2 games that dont have this are: god of war 1 and 2, castlevania lament, virtula fighter 4 evo.

Any know whay is this happening thanks?

It's the tv! There are none of the issues mentioned above on my set. Its an interlaced set... it probably does not have a good comb filter... Not that its a fault, it just how the tv is processing this picture. Aka 1080i.

Most of the games you said are 720p. My guess is that they are falling back to 480p and then being upscaled to your tv resolution, thus causing artifacts.

Ok so what type of display wont have these issues? Becasue I already been through like 5 diffrent lcd hdtv displays recently with the same issue. I even had a 800 dollar sharp aquos 32 inch with same issue.

How come some games do it and some dont? Even the sony ps3 demos at the stores do it too with those sony bravias.

Now I heard that the people dont notice the artifacts because they are not looking for them, but once you see it happening its hard to not notice when playing the games.

Thanks..

His TV accepts 720p. Nonetheless it may have something to do with the TV scaling the incoming 1280x720 signal to it's 853x1080 native res.

But again why some games do it and some others?

Looks like I have to answer my own question. Is it becuase the games that do it are interlaced games?

Question: What resolution are you running these games in? 720p or 1080i? If the only games that do it are the ones you're running in 1080i then try running the games in 720p. Everything you describe sounds like screen jitter common with interlaced games. I saw it in many of my old PS2 games on my old CRT and see it now when I play PS2 games on my Sharp Aqous.

Gosh man I just dont get it, so are the games that do the interlacing artifacts, are they interlaced games or something? You ask me what resolution i'm running the games at! Well I have the ps3 setup at 1080i and still have the checkmark enabled for 480p and 720p. So when I load up a game that has a interlace issue like uncharted, well according to my tv its running at 720p.

Ok now I heard that my doesnt naturaly support 720p, it will upconvert it to 1080i, but the display info says 720p it doesnt say 1080i. But by the looks of it looks like it is converting it to 1080i becuase when i load up a 720p game I see the modes changing within tv. But if i load up a 1080i game call of duty 4 it has a seamless smooth non changing up resolution modes becuase the "game" "tv" and "ps3" console are all running at 1080i.

1. So what i'm trying to determine is are all these games interlaced games and it will show the issues we're talking about here no matter what display you have!

2. Or do I need to get a display that natively supports 720p unlike my sony crt, to not have these issues! If this is the answer then why out of all the 5 lcd's hdtv's I had recently had these same issues going on? Even The last lcd display was a 800 dollar sharp aquous 32 inch that did 720p and 1080i did the same thing.

I would think that running a game that does 720p on a display that does 720p natively wont have these issues, but i'm pretty sure all the displays had this thats why i returned them i couldnt ignore the issues to enjoy the games.

The ps3 kiosk stations at the stores for you to play demos of the ps3, do the same thing i'm describing here, and they run those sony bravias lcd's.

The reason i'm bothered and looking for these artifacts because about a year ago i had a slim ps2 and bought a lcd hdtvs and regular lcd displays like the gateway fd-2275 that has multiple inputs and by running the ps2 it looked awful I saw combing/interlacing issue etc. So now my brain is trained to look for these and once you see them they start to bother you.

Can somone please with a ps3 and some type of hdtv load up some demos and see if you see this! All you do is pretty much stand still and pan the camera left and right "Horizontaly" and while doing so look and stare a still objects in the game/background etc and you will see the image get like double, out of focus, non clear still image, shake, etc. Thanks...

Ok first things first, none of these games were made to render in 1080i, they're all meant to render at 720p. If you output 1080i then you're actually rendering at 960x1080 and interlacing that render. If you output at 720p then your TV is going to accept that signal and scale it to 853x1080i which is your TVs native res.

The thing is since your TV accepts 720p that's what the PS3 is going to output on all your games. Try unchecking 720p and playing a game with 1080 support (like Uncharted), this will force the PS3 to output at 1080i.

If you're still having these problems my best guess is it's just the games since you say they did this on all the LCDs you've tried them on even when outputting 720p.

The thing is that uncharted doesnt do 1080i/p it does 720p. I have tried that anyways by unchecking/disabling 720p on the ps3 and still same issues goes on.

I understand you and other people are saying, its just I havent ehard fromsomeone trying my steps and telling me "yea this issue you're describing happens to me too". I would gladly wont let this bother me if I knew everyone elso has this and nothing we can do since the software makers made the games like that.

No offense man because I want to help but can you please proofread your posts, it's really hard to understand what you're saying.

From what I can tell it sounds like this is a problem with the game if you have indeed tried 720p and 1080i on your TV and five different LCDs and all of them had this problem. Also FWIW Uncharted does have 1080i support so I have no idea why that's not working for you.

I'm typing fast so its like a rough draft! Well according to the box it just says 720p, unlike call of duty 4 and others it will say other modes too, plus the game wont run in 1080i on my tv just 720p so that proves true that it does 720p only I guess.

Well thanks for your help, i'll just wait to see if someone with a ps3 tests my issue. Thanks...
