1. **Bulky and Heavy** Despite being a miniature CRT, it is still heavier and bulkier than modern flat-panel monitors, requiring careful placement and stable mounting.

2. **High Power Consumption** CRTs draw significantly more power than LCDs, which can increase electricity costs and may not be ideal for portable or low-power setups.

3. **Limited Connectivity Options** Older CRTs often lack modern inputs like HDMI or DisplayPort, relying instead on VGA, composite, or RF inputs, which may require adapters for newer devices.

4. **Maintenance and Repair Challenges** CRTs are complex and delicate; repairing or maintaining one can be difficult and costly, especially if the tube is damaged. Proper handling is required to avoid screen burn-in or damage.

5. **Heat Generation** CRTs generate significant heat, which can make them uncomfortable to use for extended periods without proper cooling. This may also pose a risk if placed near flammable materials.

6. **Limited Adjustability** Unlike modern displays, CRTs often lack built-in features like built-in speakers, USB hubs, or ergonomic adjustments, limiting their versatility in modern setups.

7. **Environmental Concerns** CRTs contain hazardous materials like lead and phosphors, making disposal difficult and requiring special handling, which can be a drawback for environmentally conscious users.

8. **Limited Availability of Replacement Parts** Finding replacement tubes, capacitors, or other components can be challenging, especially for older models like the E4103/B/4.
