This is a petition to try to convince Sceptre to release an updated firmware for TV model U435CV-UMC. The changes in the updated firmware should include the following:

1. Ability to save options changed in the service menu

2. Ability to disable auto-dimming

3. Ability to customize the no-signal standby time, just like how you can customize the sleep timer.

4. PC Mode which disables HDCP 2.2 to allow extra bandwidth for 4K@60Hz. I realize this one may be wishful thinking, but can't hurt to ask. :)
