OK well the hissing has got a lot better since I worked out I can shuffle the usb devices around and I am still using the keyboard directly to usb rather tha the pin adapter. I now have a much stranger issue in Windows, whilst I realise this is not a windows forum, wonder if the knowledge of linux software can help my windows problem.
OK so I installed a new graphics card which my nephew had, its a Asus Radeon HD7750 1GD5 V2. It works perfectly fine in ubuntu 20.04 and the linux install runs both my pc monitor and the tv as duplicate screens fine.
the card showing output to the monitor via DVI cable and the TV via a HDMI cable, during boot up of windows 10 the TV turns blank stating no video available and I cannot see where I am going wrong here. The monitor is apparently seen by the software from asus which I downloaded the correct drivers for this card Asus Radeon HD7750 1GD5 V2 as you can see in the print screen as display 1 32w LCD TV and it obviously too sees its connection via the HDMI so why isn't it using it?
The computer boots and shows the initial bios loader on both screens but it just turns off the monitor during startup of windows 10. Now heres the weird thing, in windows I can extend the display to both screens fine, however if I go to duplicate it wont work at all. Do you think whomever made the software for linux drivers for this card made some for windows users too? Now I tried using an old monitor which is vga instead of the dvi by using a dvi canle to vga adapter and this meant I could see duplicate desktops however this then created a whole new problem. The windows software will only let you duplicate the screen by using the same resolution on both, where as in linux I can have different resolutions. This meant new problem of I either get full screen on the smaller monitor and a shrunken desktop on the larger tv or I get at another resolution a full tv screen but with a reduced screen on the smaller monitor.
