Matte vs glossy

Hello, I'm debating between each for gaming. However lighting can be a concern for glossy. I have a giant windows to my left but have a blackout curtain up usually only allowing 30% of the windows to be showing. Its never direct light but usually pretty filling. I also usually have a lamp with a shade on it behind me but a ways back and higher than my desktop area. There is also a ceiling fan light thats semi on the dimmer side I have on. Would these greatly reflect if at all? Maybe I go matte but then the blacks look terrible IMO.
