I've had my LG Ultragear Monitor (model 27GR75Q-B) for a while now, and the stock power cable just isn't cutting it anymore since I switched to a standing desk. I'm searching for a longer power cable to fit my new setup. If anyone knows where I can find one or what specifications I should be looking for, I'd really appreciate your help.
The information on the existing power cable states the following:
Input: 100-240V ~ 50/60Hz 1.2A
Output: 19.0V ~ ~ ~ 2.1A 39.9W
Model: AD2137S20
Type: 055LF

You don’t actually need to buy a whole new power adapter! Just search for a ‘clover power cable’ and get one that’s long enough for your needs. Alternatively, a standard power extension cable will work just fine if you're just looking to extend the reach without changing the main cable.
One option is to mount the power supply unit on your desk and just use an extension cable from there. It could help keep everything tidy and give you the length you need to connect it effectively.
You can find a C5 power cable if it’s polarized (with a 3-prong connection toward the wall and a brick that looks like Mickey Mouse). If it’s a 2-prong cable (like the infinity or figure 8 shape for the brick), look for a C8 cable. This should solve your length issue without any unnecessary modifications.

The setup requires the existing power block to stay put, so I can’t really use a regular extension. It's complicated because the power connection is already tight due to the distance. Any other suggestions?
