Ive been trying to get my display working correctly. Its an older TV with an HDMI port. There are no settings available to change resolution in the device itself.
I ran mhwd and installed the latest NVIDIA driver for my card. Its a Geforce GTX 1060 3Gb. Im running Manjaro Gnome.
I tried taking a screen shot to upload but the screen shot is “correct” in that it shows the whole desktop. However in the actual userspace, the desktop is slightly zoomed in and crops off most of the top panel and both sides of the display. Some of the Gnome launcher is cropped at the bottom too.
In the past, using underscan in nvidia-settings has been able to fix this however I am not seeing it as an option. Additionally, on other distros recently this has become a problem in that underscan doesnt fix the issue as it once did.
Please provide your system settings as described (below).
I’m sure someone will offer further assistance when they are able.
Regards.

Update Announcements
The Update Announcements contain important information and a Known Issues and Solutions section that should generally be checked before posting a request for support.
System Information
While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly;
Output of the inxi command (with appropriate parameters, and formatted according to forum guidelines) will generate information useful for those wishing to help:
I’d be surprised if the set (or any TV or monitor, for that matter) had its own such settings, but there may be a setting to turn off “overscan” or whatever your set calls it; I’ve had to do this on one of my sets and IIRC the option wasn’t obvious.
It will help if we know the make and model of the TV.
But there should be a way to explicitly tell your computer to use a specific resolution.
Perhaps for some reason the monitor is not correctly recognized and this does not happen automatically.
You should be able to set it from some settings dialog in Gnome Settings (or however it is called in english).
I don’t have Gnome in front of me right now and can’t be more specific - I know this can be done in Xfce4.
BG405 is right. This is without any doubt the standard TV overscan problem, and to be fixed that sides, not computer-sides. Unfortunately, “overscan” goes by many different names among brands. RTFM or e.g.
Overscan can sometimes be adjusted at the system level or the monitor itself in some instances (as I recall).
Earlier versions of Mac OS for example had such a setting (a simple on/off toggle) dependent on the kext used, though even so, I’ve not had to bother with it for what seems like a decade, at the very least.
Edit:-
For the sake of minor clarification, when I generically refer to “monitor” I also include devices such as a “TV” in that loose description.
I recall that option too – not the name, specifically, but using it on occasion when I was still an Nvidia fan boy (over a decade ago). I haven’t used a “TV” (or Nvidia) in all that time, so I can’t say I noticed when the option ceased to exist.
Might be worth mentioning that I just checked the menus on my current Samsung T24C300 and there are a number of settings for PC use: size, geometry, position, hue etc. but these seem only to apply with VGA input (not selectable with HDMI).
Yes, as mentioned earlier, there are often more features available than we’d expect to see – not that I typically bother looking for them; it’s usually a case of plug-n-pray.
This is the overscan - a thypical problem/feature when using tv as monitor connected with hdmi. (It is not like the other topic where parts of screen were assymetrically cropped). It is usually 5% from all sides. Some modern TV has options to correct it in their settings, but not all.
I am not sure if there was a setting for this in the settings panel. I think i have seen it but i am not sure.
Otherwise you will have to play with the command line, probably with xrandr but have not done it so i cannot help further.
… And neither can I, until we know the set’s make and model information.

should at least give a clue as to the display device’s heritage. Then, we can look for documentation to see if there is a suitable setting.
Note that “overscan” was an intentional “feature” to get rid of “rough edges” on broadcast images; particularly analogue ones; where this made up for the fact that older (CRT) TVs would hide such by their very nature … older ones weren’t exactly “square” and broadcasts were given a “safe area” which should always be visible (I can’t remember the exact terminology).
I have one of those (a spare) right near me now, and a couple of old ones with that ratio. But what I really meant was CRTs naturally tended to cut-off the periphery, particularly from off the horizontal and vertical axes and with more modern sets with purely rectangular screens the peripheral content which “wasn’t meant to be seen” was purposely hidden from the viewer, by the set makers.
With my vintage sets, I spent some time tweaking to get as much of the visible image on-screen, without obvious gaps at the edges. But not everyone did that back in the day.
Historically, the first broadcasts by the BBC also used that ratio, which was later changed to the more familiar 4:3 aspect ratio.
