recommended monitor switch for laptop or desktop selection

wrote: the real question is why anyone is using vga in 2015. it's obsolete. People are still using it because it is still available, it still fills the needs of many people, and it will be around for quite some time. just like vinyl records. meanwhile, the rest of the world has moved on to much better standards. I just treated myself to a new TV set, because the old 21" analog CRT TV in my living room failed. The new 32" LCD LED set has among it's connections... wait for it... VGA. it also has hdmi inputs, likely more than one. Of course, I don't care that it has a VGA input; I'm using the RF "F" barrel connection to hook up my antenna on the roof. why am i not surprised. I realize that in your world, everyone must do exactly as you say, but one day, you may come to realize that it doesn't work that way. People will do things that may not be in accordance with your way of thinking. i'm not telling anyone to do anything. people are free to use outdated standards, which you clearly do, but they should be fully aware that it's outdated and that the results will be sub-par. vga is obsolete. it came out in the 1980s and has long been surpassed with dvi, hdmi, displayport and thunderbolt. |

Thanks. Try a google search for KVM switch tom's hardware. There are several threads on Tom's site, stuff there always seemed believeble to me. Prices vary alot. Some time ago, I had two computers that I wanted to use with one set of monitor, keyboard, and mouse. I used a KVM ("Keyboard, Video, Mouse") switch with good results. In my case, one computer was running Win95, the other Win98 (I did say "Some time ago"!). The switch was activated by a key combination. You will want to make sure that the required key combination is not something you already use. IIRC, mine used CTRL-PrintScreen. I had one like that until I replaced a PC with one that had only USB for the keyboard and mouse. I replaced the KVM switch with one from IOGEAR with a wired switch that sits on the desk and still use it. It did have an issue with a hum in the switched audio which I solved by using two speaker sets plugged directly into the PCs to bypass the switch. The system worked well, and the gadget cost around $40. In your case, since you want to switch only a monitor between two computers, I don't think a KVM switch would work. But anyone who sells a KVM switch probably sells a monitor switch, so starting your search there will probably work. Surely there is an electronic version of your mechanical switch. There should be no reason a KVM switch would not work for just video. The signals are independent. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

Care to elucidate? vga is analog and subject to artifacts, even without a kvm. this is especially true with low quality kvms, like the garbage that someone linked which doesn't even pass ddc, resulting in a low res image. what kind of idiot designs a vga kvm that doesn't pass ddc? vga is obsolete. it's time to move on. the quality of dvi, hdmi, dp and thunderbolt are *much* better than vga, even on the same display. nearly all displays these days have multiple inputs, eliminating the need for a kvm entirely. choose which input on the display itself. here's a display chosen at random, which has *three* inputs: dvi, vga and displayport. http://accessories.us.dell.com/sna/p...s&l=en&cs=04&s ku=320-2676 and another display which has dvi, hdmi and displayport. note that there's *no* vga: http://www.eizoglobal.com/products/coloredge/cx271/connectors.jpg eizo's 4k display (not possible with vga) has two hdmi and two displayport: http://www.eizoglobal.com/products/c...18-4K_connecto rs.jpg |

I have seen KVM switches that have a switch on the device itself. I assume these would work for video alone. I don't have personal experience on that. But, of course, we all know by now that (according to nospam) ALL VGA devices should be relegated to a trash heap, and erased from the collective memory, ala George Orwell's 1984. VGA is no good, VGA is a blight on humanity, VGA might die. nospam has so decreed. -- Ken Hart |

VGA is no good, VGA is a blight on humanity, VGA might die. nospam has so decreed. although you're trying to mock me, that's pretty much true and it's not my decree either. technology moves forward, whether you like it or not. the fact is that vga is obsolete. it's analog and produces an inferior image. it came out in the late 1980s, about *thirty* years ago, and has long been surpassed by several different options, including dvi which dates back about *fifteen* years, which has largely been replaced with hdmi and/or displayport. there are always laggards like yourself who are stuck in the past. you no doubt still use floppy disks and a dot matrix printer loaded with fanfold paper that is is connected via a parallel port. |
