PLEASE help, Undergraduate Student (render + PSD + PP)

Hi all,

I've been rendering in Keyshot at 1920 x 1080 at 300dpi, which is perfect for powerpoint slide set at 16:9 aspect ratio.

I've placed a finished rendered image into powerpoint slide expanded it to fit then viewed in full screen everything looks fine.

Once i opened it on photoshop then resaved it without doing anything, save as JPEG 12 maximum quality setting, i then placed it back into Powerpoint and view full screen the image is now slightly BLURRED.

I've done everything on photoshop, when i open the rendered image it changes the setting from 300dpi to 96, i've increased it back to 300 and also done the image/document size to 25.4 x 14.29 which is the 16:9 aspect ratio of powerpoint still no luck! When i view the original image and the saved JPEG it looks totally fine everything is retained but when placed in PP it just looks blurry? where as the original one does not i don't get it

Please can someone help, THANK YOU in advance for your time everyone!

I think i may have found solution instead of saving as JPEG i tried PNG which works, however i still don;t understand why JPEG is doing this?

I think you misunderstand the sizing / dpi. You are not rendering an image that is sized 1,920 x 1,080 @ 300dpi, but rather an image that is 6.4 by 3.6 inches @ 300dpi. This results in an image sized 1,920 by 1,080. The resulting image is 72dpi, and you will have to adjust it PS to a 300dpi image.

I hope this makes sense.
