A:Answer Regrettably, we are not familiar with the type of Thunderbolt-to-HDMI converter that you intend to use. The LG HD 720p Smart LED TV - 32" Class (31.5" Diag), Model # 32LJ550M can be used as a monitor when connected to any computer that has an HDMI Out. You will need to inquire more about the Thunderbolt-to-HDMI converter to see if you can use it as intended...^IFV
