Hello, No technical difference: same brightness, resolution, functions, power consumption... The QX came out in 2024 compared with 2023 for the QE, ... it's just a different letter for this new version.

Due to different suppliers and delivery conditions, there may be price differences compared to other suppliers, especially in international comparison. We always try to offer prices in line with the market, but this is not possible for all products.

That's a very good question, because it shouldn't actually be there. Thank you for letting us know. We will be happy to pass this on internally to the relevant department and hope that it will be looked into promptly.
