Hi, the room is so small, it`s just an "average" sized enclosure! You need an ambient temp around 24c (75f), then a basking spot with a surface temp of between approx 50 to 60c (120 to 140f).... Humidity between approx 50 to 80%, the lower figure will be around the basking area, that`s inevitable and acceptable...
And by the way, you shouldn`t be force handling the monitor at this time.
