Liking it so far. But when I'm using the eraser, line, or other tool, it automatically changes back to text add mode after saving the change I've made rather than staying with the eraser, line drawer, etc. If you did it this way b/c more users keep erasing, adding lines, highlights, etc when they intend to make only one change and start typing then nevermind. I would rather it stay with the eraser, highlighter, etc. and I'll switch back to adding text when I'm ready to do so. Hope that helps.

It was difficult for me (86 years old and somewhat "ok" with Windows 10) to figure how to send the document to my partners vie email for their markup, etc.

Super application that allows me to fill out and sign forms without printing, hand-filling, scanning and forwarding. Have used for tax forms, banking, applications, job change, legal forms, etc... terrific!

Helpful, does what I need to do. The only reason I gave it four stars is because you can't see the comments unless you are online and sometimes I am traveling to places without wifi access so it would be nice to view my downloaded documents and see the comments I attached to them.

The software is easy to navigate and user friendly. Not paying the Adobe prices. The software is very intuitive which is reduces time determining and understanding feature sets about the tool. Some features require a different level of membership which cost more and should be included with the basic package.

720p has an image resolution of 1280 pixels by 720 lines. Its quality is not much better than 720p TVs. 1080p has a resolution of 1920 by 1080 pixels, and it is a progressive scan display rather than interlaced.
The 1080p signal has the distinct advantage of actually existing. There is no 780p HD (high-definition) signal, but it's a common mistake. There is a 768p, but even that is more often lumped in with the 720p standard. The 1080p signal improves the resolution available on the 720p signal more than two times over.
Because there are more pixels in 1080p, less anti-aliasing is required for a smooth visual experience. This means that 1080p will not only likely look better than 720p, but will lead to a better gaming experience overall, as anti-aliasing can slow down a console or computer.
So to answer your original question yes, 1080p is better than HD because HD refers to 720p and FHD refers to 1080p. You didn't provide your criteria for better. HDTV standards define HD as 720i, 720p, 1080i, or 1080p video (1080i and 1080p are also sometimes called Full HD).
No. It's the bare minimum. If you want to play all upcoming games st the lowest graphics setting then sure it's good enough. So up until now for all games in the past 1080p was enough.
In short, it depends. The difference between 1080p and 4K is undeniable in that a 4K screen is capable of displaying four times the number of pixels as a 1080p screen. From a distance, it is virtually impossible for someone to tell the difference in quality between a 1080p and 4K screen.
For comparison: 720p (HD)is about 2 times better definition. 1080p (Full HD) is about 5 times higher definition.
For many, there will be little to no noticeable difference between 1080pknown as Full Hand 720pknown as HD. However, those who pay more attention will definitely notice that 1080p results in a smoother, clearer image, and that 1080p is clearer than 1080i.
