Question Display 7 Inch power consumption

[Milan.90]

I have two monitors both is connected with digital port on GTX 1060 6GB card. NOw i want to use one small display as third and I bought waveshare 7inch IPS/QLED 1024 × 600 HDMI.

Now i have some problem and i have question, when i use only my 2 monitors GPU power is around 12-14W and temp is good something about 45-55 C without active fans, but when i connect this small 7inch screen GPU goes up to 30W and now i have problem because temp is go around 60C and fans start spinning for short time while temp is back to 50C and again goes up to 60C, but before i bought this small screen i have test my GPU and HDMI and i have try with 42 inch TV 1920x1080 and GPU power consumption was max 16.18W with 2 monitors and TV. How is it possible that one small screen uses more power than 42 inch 1080P TV?

The most common cause I've seen for this is the refresh rates don't line up, so the GPU has to go into a higher power state (i.e., higher clock frequency)

It's a 60Hz refresh rates display.

all of them is 60hz?

Yes all. Also i have try with custom resolution 800x600 and rafresh rate 30Hz for this small screen but all is same.
