Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_name_47 (maximum_fps VARCHAR, least_compression_at_maximum_fps VARCHAR, height VARCHAR, least_compression_at_24_fps VARCHAR)

### Question ###
What is the maximum fps HDRx with a height larger than 1080 with a compression at 24 fps of 6:1 with a compression at maximum fps of at least 7:1?

### Accurate SQL ###

SELECT maximum_fps AS HDRx FROM table_name_47 WHERE height > 1080 AND least_compression_at_24_fps = "6:1" AND least_compression_at_maximum_fps = "7:1"
