Hello,
I plugged my PC tower (recent) into my LCD TV (recent) with an HDMI or cable. The TV is therefore used as a monitor.
I have the built-in DVB-T on the TV.
My problem is the following: when I have the PC turned on, it is impossible to get a good DVB-T signal if I want to watch TV, so I am obliged to turn off the PC to watch television.
In short, PC off: TV works; PC on: virtually all channels receive an insufficient signal to be viewable.
And I would like to permanently keep my configuration.
Thank you for your help!!!
Configuration: Windows VISTA

I have the same problem but no solution :(
Have you found a solution yet?
Maybe the antenna cable isn’t sturdy enough?
I can get a better signal (or worse) by moving it.
Even stranger:
Right now as I’m writing, the problem doesn’t occur, but if I reduce the window and my desktop is shown, it starts glitching! o_O -
I encountered a similar problem on 4 TVs I traded, all of them except the last one (3 Sony and one Samsung):
Each time a device connected via HDMI to the TV is turned on, it makes the DVB-T reception jump with varying intensity depending on the device and the channel... The loss of reception ranges from heavy pixelation and freezing of images to complete signal loss.
With different HDMI cables priced at 30 or 40 €, the problem occurred systematically.
I then bought a no-name HDMI cable for 9 € at Carrefour and then miracle ... no problem at all.
Salvation probably lies in buying a low-end HDMI cable. That was the case for me.
Or otherwise, you should look at the antenna cable. With an antenna cable at 15 €, I had three times more disturbances than with a 6 € cable. But perhaps with a very high quality cable (>120€) this might also solve the problem ???
Best regards,

Similar problem; the issue actually comes from the lack of grounding on the TV. If you’re handy (and the TV is no longer under warranty), you can replace the power cord with a grounded one (I used a PC cable) and connect the ground to the metal housing of the TV.
