Created attachment 848880 [details] Screen capture on Gnome3 as shown on my 26 inch TV set Description of problem: I've got a 26" Samsung TV set where my computer is plugged on. The TV is detected as 'Samsung Electric Company 7"'. Gnome3 seems to use this size information to scale text it displays. This way every text on screen is huge. Version-Release number of selected component (if applicable): How reproducible: Always since I updated to F20. Steps to Reproduce: 1. 2. 3. Actual results: Text is displayed too big in Gnome3 (only with Gnome3 on F20) Expected results: The screen size is well detected so the text size is well sized on Gnome3. Additional info: This has already been reported here by mochapenguin : https://fedoraproject.org/wiki/Test_Day:2013-10-23_Graphics_Radeon#Results
I'd like to add that I'm seeing this same problem with an NVIDIA card. I do not believe this problem is specific to xorg-x11-drv-ati, xorg-x11-drv-nvidia, or even xorg-x11-drv-nouveau as I'm getting this problem with or without proprietary nvidia drivers installed. Perhaps xrandr is to blame?

I can concur that the same thing happens when a Samsung LCD-TV is connected to a A/V Receiver (Denon). In this case an Asus B206 (ATI) is reporting a 7" Denon monitor.
Nicolas, Griffin and Johannes, can you please attach your /var/log/Xorg.0.log and /var/log/gdm/:0.log files here ?

So I've a 24" Samsung TV which has the same issue, looking at the logs it seems that the TV is simply lying about its size, its EDID info reports: [ 27.110] (II) RADEON(0): Supported detailed timing: [ 27.110] (II) RADEON(0): clock: 148.5 MHz Image Size: 160 x 90 mm [ 27.110] (II) RADEON(0): h_active: 1920 h_sync: 2008 h_sync_end 2052 h_bl ... [ 27.110] (II) RADEON(0): v_active: 1080 v_sync: 1084 v_sync_end 1089 v_bl ... Notice the size, I guess Samsung is doing this because people tend to sit further away from a television then from a computer monitor, so they are reporting a 7" screen size to make the OS show everything bigger then normal. If you're using gnome, you can do "yum install gnome-tweak-tool", then run gnome-tweak-tool, goto Fonts and lower the scaling factor, that has made things usable for me.

I've just reported the EDID data anomality to Samsung support. They have reported in the past within a week or so.
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
Sorry, but I am seeing this bug in a brand-new Fedora 27 (MATE version). I don't know what you'll need to know, so here is some info from 'inxi': System: Host: popcorn.neverhood Kernel: 4.15.15-300.fc27.x86_64 x86_64 bits: 64 Desktop: MATE 1.19.3 Distro: Fedora release 27 (Twenty Seven) Machine: Device: desktop Mobo: ASRock model: H110M-ITX serial: N/A UEFI: American Megatrends v: P7.00 date: 10/27/2016 Battery hidpp__0: charge: N/A condition: NA/NA Wh CPU: Dual core Intel Celeron G3930 (-MCP-) cache: 2048 KB clock speeds: max: 2900 MHz 1: 800 MHz 2: 799 MHz Graphics: Card: Intel HD Graphics 610 Display Server: x11 (X.org 119.6 ) drivers: modesetting (unloaded: fbdev,vesa) Resolution: 1920x1080 OpenGL: renderer: Mesa DRI Intel HD Graphics 610 (Kaby Lake GT1) version: 4.5 Mesa 17.3.6 My TV set is a crappy old Samsung "le32n71bx/xee", which was working fine when connected via VGA to a laptop (except there was a buzz in the audio which varied according to general brightness of the displayed image; this does not happen over HDMI). I just now upgraded to a much better HTPC running Fedora 27, and it was working excellently when plugged into my desktop monitor -- but when connected to the TV, I can apparently only see the middle 4/5ths (or so) of the desktop. I have been struggling with xrandr and modelines, but just end up looking at a blue screen saying "resolution not supported". Please help me fix this!
