Display size issue

[Amatt]

Hi all,

Just wondering if anyone can shed some light onto what will be causing this issue, I'm talking from the point of a fresh install of an OS:

I'm using a 22" UMC TV and GTX 560ti linked via HDMI cable.

When I first connect up my monitor the display is bigger than the physical screen (almost asif it's zoomed in). Usually I get around this by using the Nvidia tool to re-size the display to what I want. However, I'm wanting to start tinkering with Linux and I'm unable to get the Nvidia tool to resize it rendering my 22" screen pretty much useless.

This issue is apparent whatever resolution I use so I'm certain that's not the issue here. I've read on a couple of threads that it may be a setting on the TV but I've not found any setting that affects this. I also have a secondary 15" monitor (VGA) which has none of these issues.

Any help/ ideas would be greatly appreciated
If further info is needed just ask.

Thanks

which Linux distro are you using?

Mint 14.1 x64, I'm a Linux noob so let me know if there's a way around it.

right what you have to do is read up on the 'Xorg.conf' settings for nvidia scaling, now, chances are you will break X server once or twice, so just be careful and you should be ok

i wish i could point you to articles etc etc, but i havent messed around with Linux since Ubuntu 10.10, so i dont know whats relevant

does the tv have a vga input. try using that to see if the issue persists.

I too had loads of issues trying to get Ubuntu 12.04, 12.10 and 13.04 displaying correctly, but on my 32" TV the top and left sides of the screen were always cut off. Tried following countless guides using xrandr and possibly xorg, you lose track after a while, also got sick of the "Failed to get size of gamma for output default" message.
Installing the driver packages only seemed to make things worse, locking me at 640x480, also couldn't get any sound via HDMI or even get it to recognise that there was a HDMI audio out. Must have done at least 6 full clean installs until one of the driver packages I used worked (kind of). Half of the supported resolutions of my TV still don't show, and when I tried to force one it killed the display, luckily a reset restored it.
10.04 never gave me any problems back when I used that though.

Hope you get it sorted, especially if you can let us (me) know what you did :lol:

Hey guys,
Through some extensive Googling it seems this is quite a common issue with using a PC through HDMI on a cheap TV. A fair few people seem confident the following command fixes the issue but I get the below error. I've tried researching it but can't seem to find anything as to what it means. Any ideas?
Thanks for the help so far

xrandr --output HDMI-0 --set underscan on


X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 11 (RRQueryOutputProperty)

A lot of TVs have certain display image setting that allows you to get the "Full Pixel", "Full", Zoom", and "Wide Zoom".... It should be on the TV remote with one of those names and cycle to the one you like best. This is what i had to do to fix my TVs image zoom. TVs are not meant for PC so when hooked up to a pc it gets all weird. It's literally a 5 second fix.

My TV has an option called "HDMI PC Full Mode", tried with that on and off as well as trying all of the zoom options and while one of the zoom options was slightly better it still didn't solve the issue. If mine had been that then Windows/BIOS also wouldn't display properly surely.

Personally I think it's either an issue with Linux not translating/receiving the EDID correctly for certain TVs and/or driver install issues as mine still doesn't report the correct supported resolutions for my TV.

Sometimes Tvs have dedicated TV inputs. Look on your tv for one?
