Can the new MacBook Pro (13-inch, M1, 2020) support a 49 inch wide external display?

Machine specs for video Support says one external monitor is supported—M1 MacBookPro 13”

Approximately 6,000 (6K) pixels of horizontal resolution.

You do not make clear the exact "49 inch wide external display"...(?)

6K equals ~6144x3160 TV

compare:

32-inch (diagonal) IPS LCD display with oxide TFT technology

• Resolution: 6016 by 3384 pixels (20.4 million pixels) at 218 pixels per inch
• Aspect ratio: 16:9
