No sure if it must be here or in General PC as it's not PC specific per say.

Anywho, my old LG TV Monitors FULL HD 25'' is starting to flick flick flick for 30 seconds+ before opening. I'm using this for TV and PC monitor as it has a TV tuner build in.
I wanted something similar but as it turns out all PC TV monitors are depricatred.
So I'm looking for a FULL HD TV to be also a PC monitor.
I'm looking at these two:

Clearly Samsung has a better performance but I was kinda wondering about the energy class as LG is class F and Samsung class G.
Anyone knows if it's THAT of an issue in consumption?
Also another thing, will my HDMI 10 years old PC will have sound on the TV or I need the PC speakers?
And finally is there another TV that you might suggest for TV and Monitor?

Thanks.

P.S. It also amazes me that my old monitor was FULL HD and cost about 200 Euros but now in order to find a FULL HD you need to pay more.
I mean what is the deal? Do we go backward?
