Need some help with screen resolution please!

[Legendary_Agent]

Hey, i know this might seem rather pointless to some but im still using the linux feature and i am still gonna present it at school, except the school doesnt have a 1080p monitor nor any hdmi lcd monitor so im gonna have to connect the console to a scart CRT TV, luckly i have 1 in my house aswell its still rly good in image quality but its like 14 years old Sony Trinitron tv lol...
So my question is when i go to yaboot.conf what res number should i use? (my tv connects throw scart) if i use rgb 60hz (video=ps3fb:mode:161 rhgb) [meaning full 480i without borders] it will stretch the image to much and makes me loose portions of the screen... if i just use 33 ill get borders if i add +128 to it ill get it to scale a bit more than the screen itself missing the actual edges, what should i do?
What do you folks recommend? thx in advance!

If you want to get rid of the borders on SDTV you need to add 128 to the video mode # for full screen then reduce it using fbset. There are several guides regarding this on on the forum ... here's one:

(note that on YDL 6.2 an updated kernel isn't necessary)

thx a tons mate i am going to look on it right now

oh ya while im at it, i would like to know how to fix my resolution for mplayer aswell, i got this 720p video and i can only access mplayer by using the terminal since the version with the spe scaling has no gui yet i believe, anyways i use it like this mplayer ~/videos/myvideo.wmv
and when its start playing its just to big for the 480i screen lol, how can i downscale it to fullscreen at 480i? thx in advance as usual

hi mate, ive tried it but i can only get it to crop of the screen instead of scaling it to fit whole without borders, whats the problem lol im using it like this
fbset -a -xres 710 -yres 450 -vxres 720 -vyres 576

(the resolution of the screen is 161 which means 576i 50hz without borders)

I haven't used fbset, but I think the xres & vxres values and the yres & vyres values have to match.

I would try:

fbset -a -xres 710 -yres 450 -vxres 710 -vyres 450

to start.

yeah ive tried it but i can only get it to crop the screen... i mean my screen edges (left, right, up and down) are displayed outside the screen... and if i try this method to resize the image in order to put them back in i can either:
1) move the position of the image (by moving i mean moving it as a whole with no changes in its size or shape)
2)crop the image making it loose even more details than before (again not resizing it)

What am i doing wrong?
i tried something like this: fbset -a -xres 720 yres- 500 -vxres 720 -vyres 500 (again my resolution is 576 without borders)

Wait - I think I see what you're trying to do.

The answer is you can't do what I think you're trying to do. Nothing will resize the screen. The screen geometry is based on the overall mode - in this case 576i. All you can do is crop it. Sorry.

What fbset is supposed to do is take a screen that extends beyond the visible region of the monitor and crop it to fit exactly. It doesn't rescale the size of the screen. You run at a fraction of the 720x576.

Normally, if you use the standard 576i mode, you would find the borders too large. fbset lets you make smaller borders from the fullscreen mode - that's all.

np, thx anyways mate, how about this?
well when i try with borders my fbset is this:
576 460 576 460
if i set it like this:
fbset -a -xres 600 -yres 460 -vxres 600 -vyres 460
it gives me error invalid argument, practically telling me i cannot make the geometry bigger than that huh?

PS: how exactly do i set it to a custom RGB res for example 640*480 geometry?

Huh? Sorry - I'm not following you here.

When you say "i try with borders", what does that mean? Do you mean you're running ps3-video-mode -v 6? If so, I'd expect about 576 by 460 if you type fbset -s. (I'm away from my PS3 right now, so I can't verify that number.)

Therefore, I don't think you can't use fbset -a -xres 600 -yres 460 -vxres 600 -vyres 460 with that mode - the screen buffer only has 576 by 460 pixels. To try the fbset -a -xres 600 -yres 460 -vxres 600 -vyres 460 mode, you'd have to use ps3-video-mode -v 134 which should be something like 720 by 576.

Or - are you running ps3-video-mode -v 134, and the only number that works is fbset -a -xres 576 -yres 460 -vxres 576 -vyres 460? In that case, then - that's the only number that's probably going to work. You could try 640 instead of 600, but if that extends beyond your screen, then I guess that's it.

PS: how exactly do i set it to a custom RGB res for example 640*480 geometry?

Hard to say how to make this happen. The PS3 is notoriously poor for supporting computer resolutions. Basically - it only supports HD (1980x1080, 1280x720), NTSC (720x480) & PAL (720x576) resolutions. Anything "computer-like" is really hard for it to do, if it can do it at all. (IIRC, the VESA resolutions listed are for HDMI only)

Your best shot is to work from ps3-video-mode -v 134 and see if you can get it to near 640x480. You probably won't hit it exactly, though.

OPEN CALL: Anyone else near a PS3 with fbset able to help with this? I'm literally across the country from my PS3 right now, and unable to advise much further until later in the week.
