question about 55" tv- showing up as a 42" display when I connect it to a computer

Hi I have an RCA 55 inch screen tv and when I connect it to my laptop and go into the display settings, it shows up as a 42 inch tv (shows up as kingston technology 42 tv). I tried plugging it into another laptop and it it shows the same thing. I purchased the tv from my local sears store 4 weeks ago, brand new in the box so I was wondering if that is showing as a 42 inch tv because that is the biggest tv that the laptops can handle? Or could the tv be refurbished with a mainboard from a 42 inch tv?

The HDMI connection sends identifying information about both devices during the handshake negotiation.  The TV identifies its capabilities in the EDID handshake; manufacturer name and model can be transmitted as one of the 4 fields in Descriptor 1 through Descriptor 4, bytes 54 through 125.

So the TV is actually identifying itself as a Kingston 42" TV.  It may be that the driver electronics for a different TV were re-used on your model and the only significant difference is that your model has larger pixels.
