Rounds and Ovals.Graphics issues

Is it just my install? I am running Wheezy (3.4.9-rtai-686-pae) with Linuxcnc 2.7.3. Noticed all my rounds are coming out oval on the screen.
In Linuxcnc, or the pie chart in Libre office. Checked and tried all settings i could find and try, no change. Tried a different display , same problem.Even the grid is rectangular in the graph screen area.
:blink: :blush:
OMG !!! round here in the attachment :woohoo: :woohoo: :woohoo:
(Copied pic to usb and attached here , using win10) compared to same screen shot by my camera.

I realise its got to do with display settings. But tried all i could find. no luck.

It might be a setting that you can adjust on the actual monitor.

Can you find the monitor native resolution from the manual?

Thanks for your response.
I tried two different screens, as well as went into their menus and reset to defaults etc. I feel its the video out from Wheezy thats messed up . I'm going to attempt a re-install and report back.

Re-installed complete from USB. Narrowed it down to display settings. cannot set a display refresh rate. When i run Xrandr , get a failed to get size of Gamma ......
Any clues to try ?

Yeah, definitely a resolution problem, been there wasted a few days and gave up.
You have a 4x3 resolution on a 19x9 monitor. Had the same problem and nothing helped on an older computer. I did try xrandr and other tricks, even editing xorg manually but no joy. It was (and still is) a monitor problem, since that same computer works perfectly with any other monitor, and that same monitor gives the same problem on any other computer. Narrowed it down to a h/v sync problem and continued using it like that ( not nice since max i get is 960x640 and some visual errors ).
