Hi,

I'd like to know how to find out the VGA output assignment for my laptop screen. Have tried xrandr | grep VGA and it says VGA1 disconnected. VGA0 and VGA2 are not of use either.

It's a Dell D520 laptop 4:3 resolution. Can anyone tell me how to force resolution settings to 1400x1050? The maximum setting in the System>Preferences>Hardware>Displays is 1024x768.

Any help will be appreciated.


Thanks!!!!

The laptop display output is usually named LVDS or similar. Run the following and report back...
The graphics hardware/driver details could also be relevant here....

It may be that a basic framebuffer driver is in use. Check the Xorg log for this information. If you need to share the often lengthy output (/var/log/Xorg.0.log), consider posting it to https://pastebin.com/ (or similar) and post the link that it generates here so that others can review it.

it's better to show us actual output instead of paraphrasing.

are you sure the screen supports 1400x1050?
to me it sounds like it doesn't, like 1024x768 is actually the max. res.?

Apparently, it's maximum resolution is 1024x768. No chance of being able to shoehorn a higher resolution like the old monitors in the 90's? If I remember correctly, it was just a matter of correct refresh rate and you can basically use whichever resolution you want as long as it fits the 4:3 format.

i've never heard of anything like that (not even in the 90s), and i don't think it's possible; otherwise everyone would be doing it.
actually i KNOW it's not possible. those are PHYSICAL pixels you are talking about, on the screen. yes, even on CRTs.

These days are long gone.

I use VGA a lot. These days a monitor reports an EDID. You can not go over the EDID provided data.
The controller in those TFT screens can not handle something.

When you have a Pentium 120 with a CRT screen you can do as the above suggested. Enforcing higher resolutions and such. This is not possible with TFTs, EDID.

The way of overwriting those sections and providing to the "external connector" is by using the xorg.conf.

xrandr can give you an output what is beeing used as of now on your box.

Do you have money to spend?



go to ebay, and purchase a newer screen with same mechanical specifications. This includes also the electrical connector and such.

Your hardware screen only supports according to https://www.cnet.com/products/dell-latitude-d520/specs/ only 1024 x 768 (XGA)

quote: Diagonal Size 15 in. This does not say how the aspect ratio is, that changed a lot. size wise and when you find the correct screen, you should be able to get to 1920x1080.

Would I suggest it?

No

it is a dell
it has bad graphic card, intel gpus are buggy and crap. I sold an ASUS K70 with similar setup, better screen, same gpu probably.
It has no class n or class ac wireless
2GiB max supported RAM
looks like a penryn cpu. I would not use it for more than youtube, and that is for sure an issue with that intel gpu!

Market value in my area around 50 Euros. less than I spend when i fill up my car with Disel
