Most of it would already said here over the monitor what (80 out of 100 points) and image (90 of 100) As for processing.
Therefore, to the "PC to the HDMI input problem":
I have bought before buying read about it anyway. (And no regrets)
But since I could not imagine why a digital image connection will not work with a PC together I have "researched".
And what can I say, it is almost no problem to set more or less awkward.
1. you have to select the name "DVI-PC" when HDMI port.
2. Set the computer to 1920x1080 resolution at 60Hz, which is slightly different for each manufacturer / driver. (Please look for yourself on the Internet)
3. you have to adjust the graphics card the "Under Scan", which is somewhat different for each manufacturer / driver. (Please look for yourself on the Internet)
4. Adjust the image settings such as contrast, etc.
In my case I have a PC with "ATI HD5770", a netbook with "Nvidia Ion" and a notebook with "Mobile Intel GMA 4500MHD" no problems.
The DVB tuner is not very comfortable and not on the state of the art of today. (60 of 100 points)
-For Times: short Tagesschau it is enough, but more is no joy. (But also due to DVB-T itself with the low data rate ...)
-Videotext Is only available with no memory or other comfort.
Loudspeakers for background music and similar useful but not with PC-speakers, the 50 class (the Creative Inspire T10 have) comparable.
Conclusion:
I have the P2770HD now four weeks, and would resist in Buy.
The service is a bit awkward but with the remote control for settling not soo difficult.
And the size is just "Wellness" for Augen.Man can two A4 pages in original size on the screen and there is still room for you bars.
And playing on the PC even more fun. (But please think of a powerful graphics card)
