Catalyst thinks my LCD is a projector, rez/scan problems

[Traumaturge]

I have a Radeon HD 7770 connected to a Philips 19PFL3504d/f7 LCD screen, rated at 720p.

When I set the resolution in Catalyst (or MCC) to 1280x720, the display is unusably small. It looks like 480 or so. It also doesn't give me any options for refresh rate besides 30Hz (supposed to be 60Hz.) In some places, the display is identified as PROJECTOR(1) and in other places, PHILIPS RADEON HD 7700 SERIES. There's a little projector icon in the setup page. The display information shows a maximum resolution of 1920x1080 and refresh rate of 60Hz, neither of which I can change. It looks like something autodetected my LCD screen as a projector and isn't displaying the correct resolution.

The workaround I've been using has been to set it to a much higher resolution. This way, I have enough screen to use but it looks grainy and text and window sizes are off. Sort of like 800x600 displays from long ago, but wide. Besides the monitor damage and eye strain I'm sure this is causing, I cannot do this anymore because I've run into an application that requires the proper resolution.

In terminal mode, about a character and a half (20ish pixels?) get cut off from each side. Not sure if this problem is related.

Sorry about the poor writing. It's late and I'm pretty frustrated. If it's unclear, I'll edit tomorrow.

Try manually setting the resolution to 1366 x 768 as that is what it's actual res is.

Do it via MCC >> Hardware >> Setup graphical server,
Pick generic LCD/TFT and set it there.

Trouble is it another one of them monitors that clam "HD ready" crap only to find it ain't as it downscale the input . TV's are notorious for this mostly.

Can you please show your

Code: Select all

/etc/X11/xorg.conf

and the output of

Code: Select all

xrandr -q

FWIW usually I'd not try to set the resolution via MCC, but just leave it at Plug'n Play monitor, if your specific model is not listed.
Then either use the means of the desktop environment or you graphics card tool to change the settings.

I actually have the monitor in MCC set as "Flat Panel 1360x768" but 1360x768 isn't an option in either my desktop environment (GNOME) or my graphics card tool (Catalyst.)

I'm assuming Catalyst and fglrx are the same thing as I see them used interchangably. Or maybe Catalyst is the GUI for fglrx. Am I wrong about this?

EDIT: D'oh! It's supposed to be 1366, but I have it set to 1360. I'd be embarrassed if this hinged on 6 pixels.

Looks pretty funny to me. You have two monitors connected to your box? Are the resolutions correct?
As mentioned, if your monitor models are not offered in MCC, please select Plug'n Play.
Also, why did you set 1776x1000 in catalyst?

Apart from that, even the specs sheet looks weird: http://www.usa.philips.com/c-p/19PFL350 ... ifications
1366x768 native resolution, but only up to 1360x768 supported resolution?

Please install the package xrandr and run that again.

fglrx is the driver, catalyst usually means the control center. But somehow they also use this interchangeably, yes. Doesn't really matter

No, I only have one monitor, the one you looked up.
When I set Catalyst to 1280x768, the actual output is far less than that. (EDIT: A web app detected 747x420.) 1360x768 and 1366x768 are not in any drop-down menus. At 1776x1000, it doesn't look right but at least there's enough screen space to do basic tasks.

I'm confused too. I have a hunch the ultimate solution will be "get a proper monitor" but you work with what you've got.

My suggestion would be to rename your current xorg.conf, then rerun drakx11 to generate a new one, and only select Plug'n Play monitor and no resolution (automatic) and then run xrandr -q again to see what the monitor offers.
Then you would also need to look at or post /var/log/Xorg.0.log to see if the ati driver ignores some of the resolutions. (e.g. nvidia driver is also pretty picky about resolutions and will ignore some of them).
Ultimately you may need to generate modelines for your monitor to get the actual resolution recognised.

See e.g. https://wiki.archlinux.org/index.php/xr ... esolutions

Did that, now have a cleaner xorg.conf.

The monitor still shows up as a projector on Catalyst. It also says it's displaying at 1280x720. Neither of those are true.

There are new and old versions of Xorg.0.log through Xorg.9.log. Anything I should grep for?

There are new and old versions of Xorg.0.log through Xorg.9.log. Anything I should grep for?

Xorg.0.log is the one from the current X session, best attach the whole file here.

Seems either your monitor does not provide correct EDID information, or the catalyst driver is picky about the resolutions and does ignore some which the monitor offers. The Xorg log should tell you.
For some context information, have a look at e.g. http://www.extron.com/company/article.aspx?id=uedid up to the chapter "EDID Tools" where they want to sell their adapters, you can ignore that.
We want to basically do something similar, but in software


edit doktor5000: Looking again, from the xrandr output the monitor currently offers 1360x768 @ 59.8Hz, you should be able to switch to that using the means of your desktop environment.
What do you use, GNOME, KDE, ... ?
Seems GNOME - so it should be https://help.gnome.org/users/gnome-help ... on.html.en
