Many thanks for your post and for your question!
The UGA-165 definitely supports 1920x1080. The issue is how well video playback performs on this resolution.
If you do not care for video games and movies, then you most likely won’t notice any lagging. However if you do, then it all depends on your system configuration.
In our office for example we are playing full motion video on 1920x1280 with no noticeable lag. However, the laptop connected to the monitor is an AMD Phenom II X3 2.1 GHz with 4GB of RAM and an ATI Radeon video card.
As you can see there are a few variables to consider that can affect performance.
It all depends on your intended usage of our products.
If you give us more details on your system we may be able to more accurately predict how good performance will be.
Hope this helps!
