Your video card has an its resolution set to 13?? X 768. This may be your maximum resolution of your video card and the size of the screen has nothing to do with it.. To tell, minimize to your desktop, right-click anywhere on the desktop and select Display Options. Look for your resolution and change it to 1920 x 1080 (this is also known as 1080p). This has been the standard for over 5 years now, but you can still buy a computer (usually a laptop) with the lower resolution with a price point of around $200. You will be sorry if you buy this.
When you check your resolution, look on that same screen for Scaling. It MUST be set to 100%, regardless of your resolution. If it is set to something higher. Segment PRO and most other software you use will not display correctly. In review, for ANYONE using Segment PRO, the resolution should be 1920 x 1080 with Scaling set to 100%. If you have an Ultra high-resolution adapter, the Operating system will recommend the highest resolution but you should only do this if you are doing some scientific work that requires that resolution. If you do have that requirement, change it only for the period you need it and then change it back. This is the correct setting for all software.
Since Segment PRO is a 3D program, I had to use programming techniques that require me to pick a static screen resolution. Had I picked 768 which would have made the user interface to display perfectly on your screen, it would have filled just a bit more than half of the screen at 1080 and this is what 95% of my users would have seen. So instead, I picked 900 to make it less bad for low-res computers and not quite as good for high-res computers. I also moved all of the least used fields to the bottom of the screen so that you only have to do a limited amount of scrolling.
I am working on a new interface that lets you detach windows like the Cutaway View. This means that you won’t have to scroll at all but it may be necessary to minimize or move a window. The bottom line is that the only way I could write Segment PRO is the way I did. I routinely set my resolution to 768 so that I can see what 5% of my users are experiencing. It is annoying when I have to scroll, but it is seldom necessary and so if this is the most annoying thing that happens to you today, you’re having a really good day. Plus, if it really bothers you, switch to Woodturner PRO as it is not 3D and so I could use a technique that allows low resolution.
