    Two computers on one monitor and view both of them at the same exact time

    I do not necessarily have to control the keyboard or mouse because I can do this on each computer now I just need to have the display of each computer on one monitor screen

    Is there such a monitor or a device that can do what I have in mind

    I am not sure if this is the right forum for this kind of question if not can you please move to the correct forum thanks

    1. If the display has more than one input, you can connect one computer to one and the other to the other...
    2. Keyboard-Video-Mouse switches.
    3. VNC or remote desktop.

        oh you want to see them at the exact same time and not switch? this is something different, nevermind. need resampling and this costs $ and not sure if anyone did this, plus the aspect ratio would be messed up...

        One solution would be video capture devices to emulate displays. Eventually this is necessary to fake a monitor, rescale, and redisplay...

          security systems have multiple inputs and share the same screen . maybe implement a security camera box somehow .

            i think most "modern" security systems are video over internet and the sampling occurs at camera, making it a software problem at the recorder. Old security systems have to resample at the recorder but I'm not sure if NTSC will do anymore...

              I have an old security DVR I was giving some serious thought about weather or not I could use it for this particular purpose but the question is how would you go about doing this is the question yes you can put on the internet if you pay for the subscription but I have chosen not to go that route

              No the monitor has four separate boxes that show different sections of my yard but the question is how you security video feed and turn it into a HDMI signal is the real question


              I found this do you think this will work

                Why that? Much easier picking up a junk screen for next to nothing, repair it and place it next to the other one. Other than that maybe a TV or monitor with Picture in Picture?

                  yeah that multiviewer probably does what you want it to do... get it, I guess.

                    The reason for getting a split screen is that would like to have only one screen on because it bad enough that I have more than one computer running because of needing to run multiple battery testing machines and all I interested in is looking at the graph for the results

                    The reason for running more than one computer is that yes you can have more than one battery testing machine on a single computer however its sometimes gives trouble going from one battery testing machine to the other battery testing machine and because you can not give the individual battery testing machines different names you sometimes you do not know which battery testing machine you have up on the screen but with a spit screen device you can assign a certain potion of the screen to a certain battery testing machine and then click the number a certain number and have this battery testing machine full screen then go back split screen


                    I want to use one 65” tv as just a monitoring device for viewing the screen because it much easier to view the graphs the bigger the screen that is the reason I asked in another post about making a smart tv a dumb tv and making not able to access the internet what so ever

                                      At least it's fixed now thanks to SMDFlea! Hopefully he can figure your why. Just think if that spam filter has too many false flag events, it keeps the mods on their toes as well with extra crap that shouldn't be happening.

                                        Or least known what triggers this particular behavior is so maybe we avoid triggering it in the future ( but will not hold my breath for this one )

                                        Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                                        Hi Everyone

                                        Lately I am experiencing the deja-vu incident on one of the led monitor like this.
                                        https://www.badcaps.net/forum/troubl...lashing-on-off

                                        The monitor is HP 27es LED Monitor

                                        The monitor will randomly blackout and display no signal and will recover again.
                                        Sometimes need to power and off again to restore the display but...

                                        Good evening, gentlemen.

                                        I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.

                                        To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

                                        Looking through my repair pictures and notes, it's been a long time since I posted anything in the LCD monitors section. So here goes that.

                                        I'm dedicating this thread to one of the very first LCD monitors I repaired (if not the first one), which was more than 10 years ago now. The monitor is a Wise Wing, model F199. It's a 19” CFL-backlit LCD. I got it for free off of Craigslist in 2009 from a guy, who said he bought it for cheap from Wallmart and the monitor worked only for a little less than 2 years before quitting.

                                        When I saw the Craigslist post, I wasn't...

                                        4 weeks ago i launched Metro Exodus Enhanced and during cinematic advertisement part ( 30 fps ), pc just shutdown.
                                        Also monitor flickered with NO SIGNAL 10 seconds after shutdown. So only monitor and pc was affected.

                                        Next i pressed only power button, rebooted again and its fine again. Happened once and i cant reproduce.
