Display 7 Inch power consumption

[ForumWT]

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

But i have some problem now, 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?

 

Anyone else have same problems with waveshare displays?

 

Only two monitors

 

Two monitors + Waveshare 7inch

I am guessing the HDMI connection is providing power for the 7inch?
