VGA cable on HD
Ok so this is the problem:
I got a new HD tv (big ass full hd and so on) and I wanted to connect my laptop by vga and set it to 1920x1080 which works fine with some low quality cable I had laying around, but low quality means its a bit blurry.
So I got myself a highend vga cabl (thick suckker) when I set it to 1920x1080 it looks cristal sharp BUT it only shows a part of my desktop (so rest of the desktop falls out of the actual screen size)
I find this weird to be honost as VGA cables should all be the same except for maybe some quality difference.
By now I even checked yet another thick quality vga cable and same shit, while my cheap ass vga cable displays 1920 formatted just fine..
Anybody with a suggestion or same issue?
Could be overscan. Check your settings on the TV or your laptop display driver settings.
thanks for the tips!
ok so overscan, i cant seem to find an option to set this on or off both on the tv and laptop, also tried the lastest drivers for my intel videocard but to no avail.
and why should overscan be different depending on vga cable?

There could be a number of reasons why, it's worth checking to see if the display is being detected properly with each cable and check that the same options are being set when you use either.
Check your TV menus and see what options they have some allow you to manual change resolution and zooming.
My Sharp has an option to change resolution regardless of what the video resolution is.
I've not used my tv with vga yet, but even with hdmi I lose some pixels around the edge unless I select an exact scan option.
Sounds like you were using a different resolution with the other cable to be honest, your computer will be capable of scaling the output down ( which would make it blurry ). But there might be some weirdness with the cable. The monitor can tell you what resolutions it supports, maybe your old/new cable is preventing that giving you different results.
Most modern graphics cards should be able to do all the widescreen HDTV resolutions that the TVs support, mine does 1360x768 quite happily via the VGA port. There is a little bit of colour fringing but nothing too bad.
Check the connectors on both the cables. The cheap cable probably has all pins, while the high quality one is missing one pin on both sides.
The pin I think is not required, but does transfer useful data. I had this issue at work while connecting my laptop to an external screen.
I think thats the issue, as the quality cable doesnt seem to recognze my screen (using a tool it give me a error that it cannot retrieve the data) while the cheap cable does.
