Hey Thanx alot smith , Lord ! That Clears up my doubts ! Really appreciate ! 
I am not sure if this is what some of you need, but, here is a list of games that support widescreen (natively/or with a hack) along with the link to the hacks (if at all required) to run them in native ws resolution :-

EDIT : errā¦lord_nemesis beat me to it..
Guess What Nemesis Created This Thread to Troubleshoot His Problem and ended up Troubleshooting Mine 
! Thanx !
Yep 
Anyway I posted my query on Dell Forums (No use calling up techsupport ) as well as WSGF. No replies so far 
. Most of those people must have 7950GX2 in SLI or 1950XTX in xfire and they would not have had to set to 1440 x 900. 
guys guys i dont understant u people 1 bit. you ppl buy widescreen lcds & you are playing the games on 1024 x 768 & 1280 x 1024. for your info its no fun doing that is it. although the game does stretch out it always looks a little bit odd as it is not a widescreen ratio. please head over to wsgf & get the patches/tweaks for the game to play it in widescreen res. it makes a huge difference.
@smith - get the nfs widescreen launcher. its a small app in which u can choose your res & make it widescreen so nfs looks pretty good. you guys can try 1440 x 900 or 1280 x 768 or 1280 x 800 depending on the gfx card.
@lord_nemesis - i am sure your screen will support 1440 x 900 as i too have a 20.1 vs screen & have played on almost all res here including 1440 x 900. depending on the game u are playing just set the res manually in the ini/cfg or get a tweak or patch for it. what game are u trying that u cant play on 1440 x 900 cause i myself havent seen the res 1440 x 900 inside the game on my screen it directly goes from 1280 x 768/800 to 1680 x 1050. but the 1440 res does work for me as i have set it manually in some games to check.
Yupā¦ the dell supports 1440x900. Atleast my 2005 on ATI does. I run oblivion at that resolution since it works without a hitch with 4xAA/8x angle independent AF. Any higher and it becomes really slow :P. 1680x1050 @75Hz is also possible though out of spec. Refresh rate means jack for lcds anyway :P.
Iāve seen in Prey, Titan Quest and Call of Jurarez. In all three the 1440 x 900 resolution is not available. Let me see if setting the resolution manually will do the trick. The nVidia control panel dosnt even allow me to add this as a custom resolution.
get coolbits for nvidia control panel. u can add custom res & override refresh rates in it & also overclock. its a registry entry that enables all these options in nvidia cp. its there on guru3d
Either that or just find hacks to run games in widescreen modeā¦ Iāve been able to run Quake 2/3/4, Painkiller, Doom 3/RoE, Max Payne 1/2, SoF2 and AOM in widescreen mode - itās pointless gaming at regular aspect ratios when you have a widescreen :S
exactly. pointless i say
Yep, I already have coolbits. Anyway the custom resolutions part does not require coolbits. But when I try to add a new resolutiom, It just says that it cannot add this custom resolution.
See you can run games at that res, and theyāll look ok, a touch stretchedā¦ What gets totally fukked up is the wallpaper, and I love high res wallpapersā¦ but the 1280x1024 ones look like sh1t :@
Note that you wonāt like the look on fps games, while rts and rpg games will hardly make a difference
on the contrary, It was the otherway around for me. Rise of Legends and Titan Quest look crap when stretched while HL2 and Call of Jurarez were a bit Ok.
As for regular desktop, anything other than Native res looks like crap. Anyway no will need to set anything lower than native for desktop as even a fx5200 or a mx4000 can handle those resolutions without sweating.
TFTās are getting better at displaying non-native res content, but thereās still a lot of work to be done.
Pull down works fine, but stretching anything looks a mess.
