Ubuntu Multimedia :: Overscan - HTPC Connected To LCD HDTV Over HDMI?

Dec 12, 2010

I have an HTPC with an onboard ATI video chipset but for hardware acceleration's sake, I installed a GeForce 9500GT video card. Everything works quite well, except for the overscan issue. I've installed the latest nvidia binary drivers (manually) but I don't see any options in nvidia-settings to solve this overscan issue.

Here is my xorg.conf file:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 260.19.21 (buildmeister@builder103.nvidia.com) Thu Nov 4 20:57:26 PDT 2010
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0"


I tried adding that ModeLine line myself (using xrandr and gtf) but that fails too. I've scoured the web and these forums, and I've seen some overscan issues reported but with no solution in sight.

Ubuntu Multimedia :: HDTV Via HDMI Flashing Unsupported

Jun 14, 2010

I'm helping a friend set up his new pc and we're having a lot of trouble getting his second monitor to work.He has a GeForce GTS250 video card which has a HDMI output port as well as VGA. His main monitor is connected via the VGA and works fine. The second monitor is a Soniq QV320H TV which he wants to connect via HDMI. The nvidia settings configuration shows both monitors (set up as separate x-screens) but the only output on the Soniq is a black screen which flashes "unsupported" about every 2 seconds. Currently the resolution is set to auto (1280x1024) but we've also tried lower resolutions (down to 800x600) with no success.

Ubuntu Multimedia :: White Lines On Sony HDTV With NVidia Card Via HDMI

Apr 1, 2010

I've had a look and can't find this particular problem on the boards (feel free to correct me if there is something useful already though). I've recently got a Sony HDTV, and have hooked it up via HDMI to an Nvidia GeForce graphics card. Surprisingly enough, I'd like to watch movies/TV this way. However I'm experiencing flickery horizontal white lines on the desktop, and horizontal lines through video. I generally use VLC to play stuff, and have the 805 Nvidia proprietary driver installed.

So far I've tried:
Changing the resolution and refresh rate (Including the native TV ones)
Using Twinview, Separate X Screen and unplugging my monitor altogether.
Uninstalling the Nvidia Drivers and using the standard ones
Re-Installing the Nvidia Drivers
Xine Player
Changing video output of VLC to X11
Using Force scaling (I think, it's a tv-specific setting to compensate for differences in native resolution)
Switching desktop effects on and off

In short, it doesn't seem to be an issue with drivers, resolution, refresh rate, video files, codecs or players. How to stop these flickery lines as I wouldn't like to have to give up on the OS over one problem.

Hardware :: ATI Radeon 57xx Using HDMI Overscan (CentOS 5.5 X86_64)?

Feb 9, 2011

So, I need to use the HDMI out on my Radeon 57xx because the DVI input on my monitor is in use by another machine that has no other way to connect to it, and I won't swap cables around all the time. Of course, because someone somewhere decided that if it's plugged in to HDMI it must be a TV and have overscan issues I have a nice black box surrounding my screen image.

In Windows I can resolve this by opening CCC and changing the overdrive settings. Thus far I have yet to be able to get CCC to open and the only thing the console tool allows you to do is toggle overscan on and off, which doesn't seem to have any effect so far. Has anyone gotten this issue resolved? Do I need to focus on getting CCC working (which I probably won't use for anything else...) or is there a console command that can handle the job? Change to xorg.conf? Anything?

Software :: Ubuntu HTPC - Intermittent Audio Buzz Over HDMI

Aug 2, 2010

I'm extremely new at Linux but managed to get Alsa .023 installed on my HTPC and sound working in xbmc. However, every 10-15 seconds when playing audio over HDMI, i get a short burst of static (maybe 0.5 seconds). The static does not interfere with the audio track. I have tried running my laptop using the same cable/tv/port and its fine (win7). Listening through the analog connection on the mobo with headphones produces no such noise. The noise happens with any audio such as ..... or xbmc.

Ubuntu Multimedia :: Monitor Is Connected Via An HDMI Cable But No Signal

Jul 21, 2011

I am running 11.04 on a new Gateway with 8 gigs of ram. It is a solo installation. The monitor is connected via an HDMI cable. Everything was great (installation running smoothly for over a month) until last night. I just installed a netgear router and was setting it up with the system to try to get Stanza on my IPAD to connect to Calibre. Anyway, i suffered a severe freeze up warranting a hard boot. I could see the drive working, ancillary drives lit up, keyboard lit up so I know the system is working. The monitor did not come on, It shows a yellow light indication no signal. It is a 28" Hansspree. I tested the monitor by hooking it to a laptop. The monitor is fine. I cannot see anything on the screen so I can't boot to repair mode or use a CD. There is no signal.

Ubuntu Multimedia :: Disable Overscan With ATI Drivers?

May 11, 2010

When I first installed Ubuntu, I installed the ATI drivers with Catalyst Control Center, too. I believe the next time I restarted my computer, it was overscanned. It had the 2 inch border around my display. It was terrible, and I wanted to stop using Ubuntu because I couldn't find a fix. I finally removed the drivers through the terminal (don't remember how) and the border was gone.

The problem is, I don't have any actual drivers for this card installed. It's a Radeon HD 4650. I was thinking of trying: https://help.ubuntu.com/community/RadeonDriver

Would the be a way to remove overscan with that? Or is there a way with ATI's closed source drivers I had the first time? Ubuntu crashes sometimes and the screen goes all weird, which I'm pretty sure is from the video card. I also can't see the boot splash for Ubuntu when starting up the computer, which I've heard can be caused by your video card.

I'd like to have the drivers for my card, but not have to worry about the damn 2 inch overscan.

Ubuntu Multimedia :: The NVidia Overscan And Fixing It?

Jun 23, 2011

I have Googled. I have searched these forums and others. I have ripped my hair out in frustration. As many are aware, custom resolutions- "What the hell" by "that's just messed up" or "Jesus Christ" by "you've got to be kidding"- are very hard to set under the new "xorg.conf isn't really used" paradigm. This should not be. Many Ubuntu users are running the OS on displays with either nonstandard display resolutions or devices which overscan the display but do not offer a 1:1 pixel display setting- such as myself, on my 50" Samsung 1080p DLP television, connected via its HDMI port.

After more than a year trying to find a hard-and-fast process for fixing this overscan problem (note that I did not say "a hard-and-fast FIX for this problem"), I have decided to turn to the collective wisdom of the Ubuntu user community in an effort to put this issue to bed for good. To that end, I create this thread.

Recent research via the web has led me to believe that the problem lies in the X server not being aware of any sort of valid modeline for my- or your- nonstandard resolution. I am well-aware that each solution for each user will be different; if you're reading this, you're probably a geek like me in the first place, and your chops are more than sufficient to tackle both biting off this huge issue and chewing it.

My question to the community is this: How do I determine the correct modeline to add to xorg.conf, how do I make it available to the X server, what do I need to do to format the modeline in a valid way in xorg.conf (if necessary), and how do I make it appear in the list of valid resolutions when I run nvidia-settings (or whatever the command is)?

Keep in mind, I'm more interested in establishing the correct pipeline for fixing the problem and allowing arbitrary resolutions to the limit of the given device's capacity, rather than an exact solution for my particular hardware. In other words, I don't want an exact answer for my situation; what I'm looking for is a method for finding the proper solution given situations similar to mine.

Ubuntu Multimedia :: TV Showing Us As Projector - Remove Overscan?

Jul 25, 2010

There's several threads dealing with overscan, but I've got an interesting twist in my setup that (I believe) is putting a kink into the proposed solutions. I'm trying to set up a media center PC with Ubuntu 10.~. The motherboard has built-in ATI graphics (3300 series), and connects to my television (Panasonic capable of 1080i) via HDMI. As can be expected, the overscan makes the top and bottom bars nearly invisible (as well as a portion of the sides).

When I run the Catalyst Control Center, it informs me that the monitor is a projector, not a TV. Try as I might, I can't convince the thing it's attached to a TV. When I run "aticonfig --tv-info", I am informed that a TV is not connected.

One question I could ask, though: does it matter? The reason I'm asking is that I can't find the "Configuration" menu option in the CCC that all the other threads talk about. I know where the little black triangle menu is, but there's no "Configuration" item in it. There's also (as best as I can tell) no way of adjusting overscan for a digital projector.

Ubuntu Multimedia :: How To Fix Under-scan On HDTV With ATI Catalyst 10.2

Feb 17, 2010

I just bought a 32" Panasonic LCD (1080p) and have decided to use that as my main monitor. Unfortunately, when I hooked it up to my computer, I had under-scan with both Windows 7 x64 and Ubuntu Karmic x64 (using a Radeon HD 4870 1GB). In Windows, there was a simple slider in the Catalyst Control Center to fix the under-scan issue. Unfortunately, the same option wasn't available with the Linux counterpart. I searched online for some answers, but all the ones I found seemed outdated, or gave me errors.Using the Aticonfig help command, I figured out how to fix the under-scan in Linux.

Ubuntu Multimedia :: Old HDTV With Component Input Only?

Feb 22, 2011

Long time Ubuntu user, but it's been a couple years.

My friend had an old Dell Dimension E251 lying around and I said I'd help him turn it into a media center of sorts. The old 52" HDTV he wants to plug it into has a broken vga input and no HDMI, so our only real option is component or (heaven forbid) S-video. He can afford to get a new video card if it's relatively cheap, and I'm not really sure what would be our best option. Does anyone have a card in mind that would be relatively hassle free? I considered getting a card with HDMI output and using one of those HDMI to component converters, but my research suggests that that won't work. Are there old cards with component out, or is there a card that makes this relatively easy to achieve?

Ubuntu Multimedia :: Getting Better Performance Out Of HTPC?

Mar 1, 2010

I have a custom built PC with a AMD 9650 2.3ghz quad core, 4gig of ram, nvidia geforce 9500gt graphics card. With windows 7 my movies look immaculate but I want that from Linux. My first problem consists of lines in my players. To test out the performance I am playing Final Fantasy 7: Advent Children Complete Blu-Ray. The video file has been ripped and placed on the HD. MPlayer has lines everywhere, VLC is very good but line every once in a while, XBMC plays bout as well as VLC. The first part that confused me was how MPlayer was worse off. I have followed all the stickies and this is a fresh install of ubuntu 9.10. The Second problem I am having is getting my onboard audio to work. My board comes with 8 channel audio support but my 2 side/back speakers wont work. I have messed with the application settings and the actual settings in Sound Preferences.

Here is a link to my board specs

Debian :: Monitor Not Detected Unless Connected With HDMI

Nov 13, 2015

I noticed that Debian 8 has a significant bug related to detecting presence of display(s). Today, I woke my computer from sleep while the LCD monitor was unplugged from power (the monitor is connected via DVI) then I powered the monitor but nothing was displayed. Next, I connected another monitor via HDMI and both screens started working. However after disconnecting HDMI cable from the second monitor the first one with DVI stopped showing anything. The conclusion of this situation is that HDMI monitor must be connected all the time.

I thought that this is caused by graphics driver, but I experienced the problem on different machines, one with nvidia driver and DVI, and the second with default free driver and DisplayPort.

I just checked that this is related to KDE. After switching to console using ctrl+alt+f1 the screen turns on, but when I am going back via ctrl+alt+f7 the screen disappears.

OpenSUSE Multimedia :: No Video To HDTV

Sep 11, 2010

I cannot get video, let alone audio, from my opensuse 11.3 box to my HDTV via the AV receiver.I have a computer and a DVR as HDMI input to a Yamaha 765 receiver. The receiver than uses hdmi to output to my samsung hdtv. I am using a ZOTAC GeForce GT 220 with an HDMI port as a video card. As an aside, I could probably upgrade my video card. Suggestions are welcome though I am concerned about heat as it needs to share space with a 4 port hardware RAID controller.

Ubuntu Multimedia :: Getting Direct TV / HTPC Setup?

Jun 11, 2010

I'm in the process of building a PC to run Ubuntu 10.04 and I want to use it (eventually) to with Direct TV. I just want to be able to use the PC as the DVR if possible. I'll accept the limitations, but I'm trying to do my homework to make it as easy as possible to use for my family.

I've started out with a BioStar M32 Micro ATX board and an Intel E5300 Dual Core Pentium 2.6Ghz processor, with 2Gigs of Kingston RAM. It runs pretty well, but I've got nothing installed yet (I'm dual booting with Windows Server 2003). Right now it's just in an old E Machines case with a new 500Gig toshiba SATA drive.

Is there a guide to what hardware I could get to work with Direct TV? Also, I'm not sure of what all is possible as far as integrating the two. If there is a guide, please let me know. Also, I would love to hear from anyone who is able to network or use Ubuntu with Direct TV.

Ubuntu Multimedia :: Lower Resolution Automatically Selected For FullHD HDTV?

Jun 10, 2010

I've recently got a HDTV LCD display (BenQ SD3742), and a nettop (Acer revo 3610) to go with it. I connected them using an HDMI cable, and I installed the latest Ubuntu 10.04 64 bits edition.I then installed the latest nvidia drivers (nvidia-current package, which is nvidia-glx-195) to support nVidia ION platform using this ppa: https://launchpad.net/~nvidia-vdpau/+archive/ppaAccording to various websites, my LCD is FullHD, so I should be able to select 1920x1080 resolution. But the automatically selected resolution is 1280x768, and in nVidia configuration panel, this resolution is stated as being "native resolution" for my screen (its name is correctly detected by Ubuntu, by the way!).If I select 1920x1080 and "Apply", the resolution is changed but the borders of my desktop are not available... and the image looks deformed anyway.Is there any way to make Ubuntu to detect properly this LCD display in its real native resolution (FullHD, 1920x1080)?

Ubuntu Installation :: 10.10 - Catalyst Control Center (Overscan Adjustments)

Jan 4, 2011

I've got 10.10 up and running like a champ. Haven't done much in it, but all was well. After a little while I went in to turn the cool effects on, and it told me I needed a driver for my ATI card so I said go for it. It ended up putting Catalyst Control Center in for me. That's all fine and dandy except on the windows side I can get into an area that allows me to adjust overscan and turn it off (its a slider for under and overscan).

This version wont seem to let me do that, so now I'm stuck with either NOT a full screen, or no ability to have fun graphic effects. While your here, how can I change the data files which I think ubuntu refers to as your /home folder (documents pictures etc) to a different location? Windows7 and Ubuntu need to see the files in the same places so I don't have to have two working sets of files.

Ubuntu Multimedia :: Cannot Get Sound Through HDMI

May 20, 2010

I have an HP 8510w laptop and I run ubuntu 10.04 out of an external harddrive.

I have no problem getting video over hdmi using the latest proprietary nvidia drivers however I cannot get sound through the HDMI cable.

I have read around without being able to find a solution.

Running "aplay -l" shows only my intel sound card and also there is no hdmi sound interface in the sound preferences (Only the normal output interface).

I am using the latest proprietary nvidia drivers (Believe it to be 1.95) and the graphics card is a Quadro FX 570.

how I can get sound out to work via the hdmi cable?

Ubuntu Multimedia :: HDMI Or DVI Mythbuntu 10.10

Dec 23, 2010

I have an ECS gf7100pvt-m3 that has the Nvidia MCP73 chipset that supports HDMI out. Unfortunately the MB only has a DVI connector which from what I have read is supposed to cross wire the audio to the correct pins on the HDMI (have a ticket in with ECS to see if like ATI there is a special adapter).

I have tried every thing but only Analog audio is working.

I've tried listed on these links to no avail:


The only error is the at the Aumix isn't touching....I can select HDMI or IEC958 1 etc etc and the audio mixer shows full blue as if it should be working but I can't get VLC or MythTV to output sound.
