hi guys, recently i bought myself a second hand 6800gt to replace my 9800pro...

let me explain quickly my setup on my 9800pro... i had my 17" hitachi lcd connected and running at 1280x1024. i also have a sony 32" widescreen television. this tv isnt lcd or plasma but the older ones (u know the ones that went back miles :P)...

anyway my setup with the ati was simple, the tv was an extended desktop and the resolution was a widescreen one 848x480 i think and all was sweet. to watch movies on it i would just drag windows media player across and double click and the movie would fill the tv...

this nvidia is proving to be a nightmare. i cant seem to find a widescreen resolution that will work. initially nvidia drivers didnt have the option for 848x480 so i tried to custom create them (nvidia has that option) but it said "this resolution cannot be added." so i downloaded powerstrip and added the 848x480 resolution. then i had to use ultramon to select that resolution on the tv. i thought i had finally cracked it but the display on the tv ended up being garbled (the wallpaper would only appear across the top half of the tv and crap in the bottom half)...

does anyone know how to fix this, or maybe i have to use a lower resolution? if so what res as i can custom make it in powerstrip or something. this tv with the nvidia card seems to like the low resolutions like 400x300 but these resolutions are not int he right aspect and when i watch movies it gets cut off on the tv screen....

plz help, this is driving me crazy :)

thanks
 
Nview display settings will let you pick any resolution your monitors or tv`s can display. ie running 1680x1050 on lcd monitor and 1366 x 768 on lcd widescreen tv .. easy. Any crt tele will overscan to a degree so one will have to mess with the overscan feature within NV control panel, but its a bit fiddly.
 
hmm thanks for that...

ideally i need a ratio that follows the 16:9 ratio as closely as possible (1.777777). with my ati i was able to use 848x480 no problem and it was fine.

this nvidia card gives no such option until i tried to force the issue with powerstrip, that didnt work well at all... any suggestions for a working resolution?
 
o yea just had another thought, when i boot up, the bios screen etc when it checks for drives that is in a nice widescreen resolution on my tv... thats what i am after. anyway to check what resolution the gfx card is using then?
 
but at post the image on my tft is 640x480 maybe but the res on the widescreen is stretched or fills out the whole screen.... if i can find that res out then maybe i can create a custom res in windows with powerstrip and everything will be peachy... any ideas guys?
 
Im sorry im not much help, but the reason i got a LCD tv, is so i can output directly to it via dvi, and thus not mess about with tv out settings, and the general loss of the image when messing with the screen positioning. I found even when i had the tv out to a crt tv all sorted, when playing various avi files each time a diff file started, it would lose its settings. If i got a widescreen tv avi say DR Who for example, tv outing to a crt tv i would lose some of the image in overscan. Direct output to a LCD tv or plasma say is the way to go, save messing about imho.
 
heh indeed but the money involved in getting one is the problem atm...

was searching on other forums and this guy has basically got the same problem as me, only difference is that he went from matrox - nvidia, i went from ati - nvidia!

I switched from a Matrox G400 to an Nvidia card (Mainly because the new MB would not accept the older Matrox voltage). It's left me with a problem which I have found a workaround for but is not an ideal.

It's a GeForce4 440 MX and has TwinView whish is the equivalent of dualhead on the Matrox cards.

I am in the UK and have a widescreen TV. The Matrox card used to have an option to set TV out as 16:9 widescreen mode and everything was hunky dory. However. The Nvidia card appears to have no such mode. I realise that anamorphic 16:9 mode is basically just using the full 4:3 res on a TV and then stretching it to widescreen to get the full resolution and correct ratio (I don't think you get any extra res from side to side on widescreen TV's. At least in 576x UK PAL land. Correct me if I am wrong).

So outputting a widescreen movie to the TV out on the Nvidia card gives a 4:3 picture and I've found the only way to correctly display 16:9 images without black bars top and bottom is to force the player to throw out an anamorphic vertical stretch and letting the TV stretch it sideways to widescreen. I do this in a player like Zoom Player. However. On the monitor it is all long and distorted. It's nothing major more of a niggle. I'd like to have a proper 16:9 output option but it does not appear that TwinView (At least on this model) has the option?

Tried TV Tool latest etc and none of them seem to have the option either.

guess the only way to fix this is to use zoom player or maybe that vlc thingy :)

will let u guys know how it works...

but 720/576 = 1.25 which is no where near widescreen ratio (1.77777 etc).

my ati allowed me to have 848x480 on my crt tv (scaled or something) so at least movies would appear in the correct ratio...

Man i might just have to complete Fear and Prey then put my 9800pro back in!!! :)

Afaik, all widesreen pal crt's work at a res of 720x576, but the pixel size is rectangle. For best picture quality, you should always use 720x576 with the crt.
