I am currently in search of monitors that range between 7 to 9 inches in size, specifically those equipped with SDI input. Additionally, it's essential that these monitors can operate in low-temperature environments, ideally at -20ºC. Given these technical specifications, I'm keen to explore if any of your Lilliput products can fulfill these requirements. Could you please provide me with a detailed list of models that fit this criteria? I'm particularly interested in their performance, durability, and any other relevant features that would support reliable operation in challenging conditions. Your prompt response will be greatly appreciated as I plan to make a decision soon.
