The term can now refer to the computer display standard, the 15-pin D-subminiature VGA connector, or the 640 × 480 resolution characteristic of the VGA hardware. I suggest also to mark this post with an advice for other people as an information for users of older monitors with output VGA.Video Graphics Array ( VGA) is a video display controller and accompanying de facto graphics standard, first introduced with the IBM PS/2 line of computers in 1987, which became ubiquitous in the IBM PC compatible industry within three years. I suggest to people that have an older TFT VGA Monitors to try to search for older cables on older pcs and buy one to have to substitution if any problem occur with your own older cable because the problem is on the new cables that are sale on market. So definively the problem is with this type of new cables on the market.Īt this time I buy a 4 new cable that is an old cable from a older pc of a person that accept 20 euro for the old cable and test here and works perfect as you can like on the screenshot→ When I test the cables on one pc with the same resolution of mine at home 1280x1024 with the cables conected the Monitor and the system dont have the output 1280x1024, I test in two machines different by my pc at home and in both the system lost 1280x1024, and on the external machines with the original cables the output 1280x1024 is present and active in one of them and with the new cables this aren't present on posible options output and cant active it by any command if try. I can now confirm that the problem is with the type of cables because I test this new cables and a third that I buy on other computer with a TFT monitor similar like mine but from other productor name, my Monitor is Acer and the other 2 that I test are from TFQ or a label like this. ![]() V: height 1024 start 10 total 1066 clock you can see with the new cables the 1280x1024 dont appear but because I dont reboot the pc when change the cable the monitor preserves the resolution of old cable. H: width 1280 start 13 total 1688 skew 0 clock 63.98KHz ![]() , I always need open → menu → arandr and then change the resolution for 1152x864, and the conkys and wallpaper isn't centered on the monitor. I dont inspect autostart resolution, in fact I have other problem with this new cable, each time that I do a power on on the pc the monitor always start in 1280x720 with a big openbox menus etc. I inspect the old cable I think that is a problem with the internal cables because if I move the cable to a certain position the image haven't any flickering color. I did the output of xrandr with the new cable in use on monitor, so this options are for the resolutions that this cable can accept. They should not charge more than 1$ for a working cable. There ought to be tons of VGA-cables in second hand shops. I dont spend more money on this I will use this cable with this resolution, if anyone have an idea to force the cable to accept 1280x1024 resolution please put the idea here to I see and test here. You might have done several changes since you wrote the post on … org-config, seven years ago. It is there you can se how you lately have chosen to connect to your screen. Maybe it only calls ~/.screenlayout/screen.sh. You ought to have some setting in ~/.config/bunsen/autostart, choosing your screenresolution. Why not connect with an hdmi-cable, to show 1280x1024, else choose 1280x800, for the VGA-cable? It can show 1280x1024, with an HDMI-cable and 1280x800 with an VGA-cable, according to xrandr.
