Which output size to display images on TV

Hi,
Which output size is good to choose during batch processing to display images on TV. I am thinking of choosing 1080 for short side and let DPP decide other size. Or is it better to leave them in full size, let TV downscale them.

Thanks,

1080p TV supports 1920x1080, so why send it any more pixels than it can display?..more pixels = extra loading time, and to no purpose.

OTOH, your dSLR aspect ratio is typicall 1.5:1, unless you shoot 4:3 format. So if you crated 1920 pixels across, then your output file is 1280 pixels tall...wasted pixels sent to the TV

So, with 1080 pixels vertically, your output file needs to be 1620 pixels wide to preserve the 1.5:1 aspect ratio, and you have 15% unused screen size horiontally.

But the way your TV handles files determines what your optimum will be. On my TV, it aways 'fits vertical fully' no matter what vertical pixel count. I see the same image on the screen whether I send original file (3888x2592) or 1920 horizontal TV width file (1920x1280) or vertical screen width file (1620x1080), so I might as well send 1620x1080 because it is only 20% of the storage space and is only 1/5 the time to send the file to the TV via wireless

Thanks for the information. I tested out by displaying pics with full resolution. It is displaying with black bars to the left and right sides. I can convert files with 1620 X 1080 in DPP itself. I can also tone down noise settings. I should see more than stop improvement in iso by converting into 1620 X 1080.
Also noticed that, TV images are saturated. There is no need to add little saturation to image in DPP. Is there any reference screen brightness I need to use while working with DPP on my laptop.

Thanks
