Question Replace CFL backlight with LED?

Got a Hanns-G HZ281HPB 27.5 inch monitor that works fine but it sucks down 95 watts and is always a bit warm. My similar LED backlit monitor only draws 30 watts. Can I swap out the fluorescent backlight for LED? I swear I've done this on a laptop...
 
I'm doubting that you will bring the power consumption down that much, CFLs are also *fairly* efficient. I'm also doubting that you will end up with uniform light.

You'll have to take the monitor apart to see what will fit and can be mounted in place of the CFL tubes, and you'll need an alternate power source since the LEDs run at much lower voltage.

On the other hand, how much effort and cost is an old, 1080p monitor worth?
 
^ Why? You'd need to settle for 27.5", still need the backlighting, also need to replace the PSU and mainboard (if not both the same board) which probably won't mount right up so the case has to be hacked to do it... probably less expensive to just buy a new 4K monitor.
 
When you replace the panel it's fitted with everything and you just need to connect the EDP cable.

Now, on an a actual monitor it's different and would need to see behind the panel to know more. shouldn't be overly complicated to do.

4K monitor vs 4K panel could be a significant price difference.

The laptop I'm using come sin at roughly $2000 with all of my addons and a comparably spec'd OEM option would easily run $2500 - $4000.

Barebone 12700H laptop - $1300
4K panel - $300
32GB RAM - $100
Ge3 + Gen4 1TB drives - $250

I would think of the Monitor casing like a drive enclosure providing something to mount the panel to and connect the cables needed. Possibly noy as easy as a laptop panel but, should be an option.
 
Not that simple, because the mainboard and PSU need replaced too. A new 28" 4K monitor can be had for $200, or a bit more for higher quality panel and other higher tech specs.
