<!-- SC_OFF --><div class="md"><p>Alright, that's an issue I'm facing since a very long time.</p> <p>I have an old TV that I'm using as monitor for my PC (with HDMI), and it has an very annoying issue: overscan. I can't simply go to the TV settings and disable it. Because the TV doesn't even have an option for that.</p> <p>I dual boot Windows and Arch Linux. And in Windows, I have the NVIDIA drivers installed, and to solve the overscan issue, was very simple:</p> <p>Go to NVIDIA Control Panel → Adjust desktop position and size → Scale mode set to "No scale"</p> <p>(the names can be not accurate because my NVIDIA Control panel is on another language, and I just translated it to english).</p> <p>Then, I got to "Change resolution" and I created a custom resolution in there, a resolution that can fit into the TV screen: <strong>1800x1012</strong> (also, the frequency rate is set to <strong>75hz</strong>).</p> <p>And done. The problem has been solved.</p> <p>Now in Linux... Not this only is an hard issue on Arch Linux, but also in other distros.</p> <p>What I could do was: Install the <code>nvidia-settings</code> package and use it to set the resolution to <strong>1920x1080</strong>, and set underscan to <strong>60</strong>.</p> <p>This solved the problem, but only <strong>partially.</strong> There are cases where the screen kind of moves along with the cursor when it's on the screen boundaries. This is so annoying.</p> <p>And there are cases where the screen doesn't actually move, but the <strong>Desktop Enviroment</strong> gets cut and i can't see the rest of it.</p> <p>I also tried to create a custom resolution in xrandr, but it ALWAYS throws the BadMatch or BadName or BadRequest error.</p> <p>Also, there is an command that I used when I was using Linux Mint and it was working, but in <strong>Arch with i3</strong> doesn't seems to work.The command is: <code>xrandr --output HDMI-0 --rate 59.94 --mode 1920x1080 --fb 1798x1011 --panning 1798x1011</code></p> <p><strong>In a nutshell, I want to be able of creating a custom resolution in Xorg that can fit the entire TV screen, with no cuts, and with no scale. And also, I don't think the</strong> <code>--set underscan on</code> <strong>xrandr parameter will work.</strong></p> </div><!-- SC_ON -->   submitted by   <a href="https://www.reddit.com/user/pvini07BR_"> /u/pvini07BR_ </a> <br/> <span><a href="https://www.reddit.com/r/archlinux/comments/rajfcb/how_to_use_nvidia_gpu_xrandr_to_remove_overscan/">[link]</a></span>   <span><a href="https://www.reddit.com/r/archlinux/comments/rajfcb/how_to_use_nvidia_gpu_xrandr_to_remove_overscan/">[comments]</a></span> |
