Hi Jun Ha,
The black image is almost surely a graphics driver problem. It is a little strange that it happens with the laptop display and not the external display. But the settings you are using are probably not reasonable. Asking for a 5000 x 3750 pixel image at 4x supersampling makes a 20000 by 15000 pixel image and then bins the pixels down by 4 to get the requested image size. Unless you are printing a poster of this image this is overkill. At 5000x3750 if it is just for screen viewing or printing on a standard letter size piece of paper I would not use any supersample (1x). If you really need these settings then you will need a better graphics driver or better graphics card.

However, if I do not change the Chimera resolution and keep it default (ex. 1024x768), it is properly imaged.
