    hey everyone ..... i have LG TV 32 inc .... just discovered that i can use custom resolution on nvidia control panel and can go from 1920X1080 to 2720X1536 .... is that good idea to keep that resolution on 32 inch TV ? or is it useless ?

    i mean .... isn't 32 inc to small for that resolution ? and will not give me much eye candy then on 1080 P ? do i need like 40-50 inc TV/Monitor to enjoy 1440P ?


    i hope you all understand what i mean .... for example on notebooks with 15-17 inc size .... for me it's pointless to have FULL HD resolution ... cause you can't see difference between 720P and 1080P on that small 17 inch screen...

    If your TV/Monitor could do 2720*1536 it would be worth it. Your TV is going to be limited to 1920*1080 though.

    Your TV is just going to scale it back to the native resolution of the panel (Likely 1080p), no way around that.

    Nope, there is a point to do this: Less aliasing. I play at 2880x1620@1920x1080 wherever performance allows.

    The displayed resolution is still 1080p, but the image is rendered with a higher resolution and then scaled down with a filter. OGSSAA (ordered grid supersampling) like in Sleeping Dogs, GTA4 ENB mod, Trine, Witcher 2, Serious Sam 3 and Arma 2 work the same way.

    Those screens don't represent the best results, look here for example:

    Look at the jaggies. It is much smoother. I would use that in games that don't support proper AA, for example GTA 4 or Crysis 2 DX11. Especially in motion the effect is very evident. I would use 2880x1620 though. "Even" factors like 1.5x1.5 (2880=1.5x1920 and 1620=1.5x1080) or even 2x2 provide the best result.

    No, it won't.

    1080p with 4x MSAA will have 4 colour samples per multisampled pixel (polygon edges and transparent objects).
    1440p downscaled to 1080p will have 1.7 pixel-sample per pixel.

    Since BF3 has properly implemented alpha-to-coverage to handle transparency (only if MSAA is enabled, iirc), the only thing you gain by downscaling is somewhat less aliasing on specular maps and shader effects, while anti-aliasing on transparency and geometry will look far better with MSAA.

    Yup, depends on the game. I would only use it where no MSAA is possible. BF3 is pretty shimmering/aliasing-free even with MSAA. In most titles even before downscaling I would use SGSSAA first if possible.

    Tried some of this stuff as well on my 17'' 1440x900 16:10 native monitor.

    Found for the most part 1680x1050 looked fantastic,1920x1200 looked way to small like some complain about on laptop monitors and 2560x1600 was not supported.

    BF3 especially looks amazing maxed out at 1680x1050 versus 1440x900.

    Forced the gpu to render the resolution at the aspect ratio of 16:10 hence my new choice of resolution.

    The TV doesn't have to display more than 1920x1080. That's the whole point.

    That everything becomes too small is irrelevant for 3D games because the UI usually scales with resolution. Only text-based games really are a problem, there it is unusable. But for example Borderlands 2 looks great in 3840x2160@1920x1080. Add in some SMAA and you're good.

    For the best image quality always use the displays native screen resolution, check the manufacturers specs to find this for your TV, it's almost certainly 1080p.

    If you run at a resolution that is higher or lower than your screens native resolution then the TV has to scale the image and scaled images always look horrible.

    TVs as monitors is generally a bad idea unless you're sitting very far away, this is because 1080p is a very small resolution for such a large screen.

    it is 32 Inch TV and i sit like 1.5-2.0 meters away ... don't think it's close .. cause many of my friends can't even see small objects from that distance :)


    okay then i will stay with my natvie resolution .. 1080P ...

    No it doesn't look horrible. What you're thinking of is for example 720p on a 1080p display. We're talking resolutions higher than the native resolution here. Take a look at the screenshots I provided and say again it looks horrible. It looks far better due to less aliasing.
