BLAUPUNKT BLA-40 / 133O - connecting a laptop to a TV via HDMI

Hello, because I've tried practically everything, I decided to write this post (maybe my TV is from outer space and you have to act "differently"

To the point, he tries to connect an ASUS laptop (RAM 8gb, 2.5ghz processor, Windows 8.1) with an Intel Graphics 4000 HD graphics card to the BLAUPUNKT BLA-40 / 133O-WB-11B-FGBQKUP-EU TV. After connecting the hdmi cable to the laptop, literally nothing happens on the TV, no signal, I tried all possible resolutions, reinstalling the drivers, etc. I will add that the laptop, after connecting the same hdmi cable to the LG TV, works fine and detects the TV itself, on a daily basis under my BLAUPUNKT is connected to the ARiva DVBT decoder and it works flawlessly on the HDMI cable, is it possible that nothing will help here and this TV set will not work with my laptop or any laptop? I would ask for any answer of a wise good man in these topics if the problem can be solved in some other way or that I would start writing an advertisement "I'll put it in good hands"

The TV set according to the specification has a built-in DVB-T tuner, so why do you need an external Ariva?
After connecting the tv and selecting the appropriate source on it, did you try the Win + P combination?

Since the decoder searches for many more channels, plus I noticed a much better image quality on the decoder than on the built-in dvbt itself, the decoder was there anyway, so I decided to use it, as for the wines plus P was one of the first steps to duplicate the lap screens on tv, best regards and thank you in advance for your interest in the topic.

My (HP) laptop recognizes the TV (Toshiba) only on the HDMI1 input. Not on others. Maybe try it is a matter of entry.
