Hi @Anonymous
I see that you are visiting as a new member! Welcome to the Autodesk Community! 
Are you buying for commercial use or for school projects?
Before you decide to buy the laptop, I recommend that you look at the reviews and cross check the system and hardware compatibility for the products that you will be using. From your post it looks like you will use it for gaming, Revit, Lumion Rendering and for Rhino. Please spend some time to analyse the features that best suit your requirements, this will help you in the long run and minimize performance issues.
Please check with the manufacturer on the laptop's black and white contrasts' ratios, some reviews mention that this does not produce the deepest blacks, however works best if you use it indoors, not for heavy gaming and hd movies. From an ergonomic perspective, I would recommend an ambient light for use indoors in a dark room.
Since you are concerned with the 'brightness' factor, the helios 300 uses IPS technology with a limited color gamut. (Color gamut is the colors that can be recognized by the human eye and this is often associated with a wider range of colors on screen). If you are used to displays in your smart phone, the brightness appears different on the laptop. However you can get a improved color profile for this laptop HERE
- See the certified system and hardware requirements from Autodesk for your version of Revit HERE
- For hardware requirements for Rhino click HERE
- To check if Lumion rendering will successfully run on the laptop, check HERE
- Also look for the Nvidia G-Sync at the page HERE regarding display settings for your laptop
- Check out the review HERE for recommended cost effective laptops for Architecture students.
I strongly recommend that you compare the software requirements for usage with the laptop of your choice and also research laptop specific reviews.
