Thomas, before rendering are you changing your timeline resolution in the Master Project settings to UHD? You can then add a Custom output setting of 1440 in the Deliver page.
Also, what were you hoping rendering at the higher resolution would do? It wont increase the quality of what was already in the 1080 video, it is merely upscaling it which will make it compatible with UHD displays and help alleviate re-encoding artifacts on YouTube. You can't add something that isn't there in the first place by upscaling.
