Hi,
I'm new to Mint (and a newbie on Linux). Anyways... I have a display issue with my Linux Mint 17.1 which is running on my new Intel NUC DN2820. I've connected it over HDMI to an old Panasonic 37" HD-ready plasma TV.
After a couple of tries, I managed to get the NUC connected over HDMI to the TV. However, the image is a bit cropped. Every side of it is just a bit too large to fit the screen. For example, I can just see the top 1/3rd of the taskbar.
I've checked the display properties and I can see that Mint does detect that I have a Panasonic TV but it detects a 32" screen whereas my TV is 37". I don't know how to change that.
I've tried several resolutions but the image never fits my the screen perfectly.
I've used the usual trick to install the Intel Graphics driver and it improved the situation a little (image is fitting the screen a tad better and colours looks better too). However, it is still not OK.
I've connected my PC to a normal PC LCD screen and it works perfectly fine with the image fitting the screen perfectly.
- Is there any way i can force a 37" monitor info in the display properties?
- Would a resolution fit the screen (or is it always "interpreting" and I will not be able to get a good image on that old plasma TV)?
My problem looks quite similar to this one:

Except that (unfortunately) I have no ATI card. I have an Intel embedded chipset.
Thanks in advance for your help.

Re: Wrong monitor size + display doesn't fit TV screen
In the TV's on-screen display (OSD) menu, turn off overscan mode by changing the input mode. Some TVs call it "Just Scan", "Full Pixel",
"True Pixel", "Screen Fit", "1:1 Mode", "Native Mode", "Dot by Dot" or possibly something else.
If these are no settings to control overscan, then type this command in the Terminal and post the output:
xrandr

Re: Wrong monitor size + display doesn't fit TV screen
Hi Robim,
Thanks for answering. I did not find any overscan option in my TV parameter panels.
!!!Crap! I'm sorry I found the option and it fixed the whole thing! Thanks a lot. Menus were in French and I went passed it cause I did not understand what it was about. Thanks a lot Robim!!!
Here's the result of the Xrandr:
For the record, here's what I see in the display properties:
Whereas my TV is a 37" (http://www.digitalversus.com/tv-televis ... specs.html).
I think there must be an EDID reading issue and Mint fills in the missing EDID info with whatever it can find in its DB.

Re: Wrong monitor size + display doesn't fit TV screen
Just to be sure, I wanted you to look at the TV's onscreen menu, not in System Settings > Display, for a setting to turn off overscan.
Another method to try is scaling the screen image using xrandr. In the Terminal type this command:
To reverse the effect, type:
If the image isn't right, then test other values:

Re: Wrong monitor size + display doesn't fit TV screen
Yep! I thought my TV set did not have that option (since there's not much in the menus). But it had it.
I had come around the scaling too. I was think about either a custom EDID or using the scaling. But none of that was necessary.
Thanks again!
