Should I use my TV or a monitor?

[Airlane1979]

I've moved from a laptop to a desktop system at home. The new (well, refurbished) Dell Optiplex system came with a Dell P2011H monitor with a 20 inch screen. I am thinking of selling or giving away this monitor and using my LED TV instead and I need advice. Partly, I'm concerned with power consumption which doesn't seem to make sense. My 49 inch TV states it uses 135W; the much smaller monitor states "240V (UK) and ~1.5A" which I assume means it uses around 360W. Is this correct? Does my big TV use much less power than a small monitor? I've also just noticed that the mini tower unit states 240V 4.6A which means at around 1.1kW it uses more than an electric heater (can that be correct?)

Those are input values. The monitor itself uses 20W typical / 45W max operating wattage.

Use your TV if you can sit back from it far enough.

If you do gaming use whatever has the higher refresh rate.
