Main Monitor Only Works When A Second Monitor Is Plugged In?
Sep 23, 2015
I am running Windows 10
MSI R9 390 GPU
AMD Catalyst version 15.7.1
Main monitor is CrossOver QHD270 via Dual Link DVI
Second display is a Vizio TV via HDMI/DisplayPort
So I was messing around with a 3 display setup for the first time today, one monitor (DVI) and two TVs (one HDMI, one DisplayPort). Everything worked okay, and I could unplug one TV, but when I unplugged the second TV, my monitor went to a black screen. As soon as I plugged the TV back in, the monitor started working again. The main monitor I use every day is now completely dependent on a TV I occasionally use as a second display to be plugged in to function. When I turn on the computer with just the monitor plugged in, I can see the BIOS load up, and the first Windows 10 logo, but as soon as the password screen should be shown, the screen goes black. I tried uninstalling my graphics drivers. When the drivers were completely uninstalled, the monitor functioned normally, but as soon at AMD Catalyst Control Center was reinstalled, it went black until the TV was plugged back in. I've tried plugging the TV up through HDMI and DisplayPort, it makes no difference. Also, my monitor is listed as the main display in both CCC and Windows 10 display settings. Every once in a while when I unplug the TV, the Monitor will get darker and slowly fade to black instead of going straight to black.
I have a two monitor set up, with my main monitor being a 27" screen and a second 22" touchscreen as a secondary monitor.
I can only get the touchscreen monitor to pick up touches if I make it my main monitor. As soon as I switch my main monitor back to my 27" monitor touches to the touchscreen monitor appear on 27" monitor.
So recently I upgraded to windows 10 at the same time I got a 4k display.When I set the display scaling to 150% on my main 4k monitor and ensuring that the scaling stays at 100% on my other two 1080p monitors, the entire chrome application is blurry when viewing on the 1080 monitors, and I cannot seem to fix this. Other applications seem to be okay.
Furthermore after the scaling change, some icons on my 1080 monitor's desktop get larger, as if some scaling is applied to them. Is there any solution to this? At the moment I have had to set the scaling back to 100% on my main monitor in order to use chrome on the smaller monitors.
I have my TV connected to HDMI and a small, old monitor connected to VGA on a Radeon 4600 video card. I have Kodi (multimedia player) set to open full screen when the default user account logs in and it does so on the main monitor which is my TV. I have the smaller, older monitor set up so I can still use the computer when someone is watching a movie on the TV. I have multi-monitor set to extend the desktop.
But my problem is when I open a program it wants to default to opening on the main monitor and when I open a program from the second monitor, it opens behind Kodi on the main monitor (and I have to click and drag it over to the second monitor) - so I would like to switch the old VGA monitor to be the main monitor and the TV to be the second.
Is there a way I can force Kodi to open and stay on the second monitor once I make my TV the second monitor?
I have a acer Z5600 and use an acer AL1916W as an additional monitor which worked fine with Windows 7, since I upgraded to windows 10 my second monitor does not work and my main screen just goes black.
Today I upgraded to windows 10, and the first thing I noticed was that the display on my main monitor was out of bounds(1920x1080 btw). I know the task-bar and icons on the desktop are there, but they aren't in the frame of the monitor. My other display is flawless, but the main one isn't. I turned down the refresh rate from 60 to 30 on the main monitor, and that let me see everything on my desktop, however, there is a flicker when I go over stuff. Also, I feel that there is somewhat of an input lag with the mouse.
I set monitor to turn off after 15 minutes and computer to sleep after 3 hours, none of that works unless i disconnect game controller, than it works perfectly. is there any way to solve this or i just to wait for microsoft to release some kind of update?
Windows 7 HP Pavilion DV7 w/ second monitor attached via RGB.Windows 10 upgrade wizard said everything was fine.Upgrade took >90 minutes. Second monitor no longer works on my laptop. (No monitor works - tried different cables, different monitors.)Contacted Samsung for support on monitor. Downloaded updated video driver.Rebooted.Windows 10 now won't boot. No system recovery options.
It worked fine in windows 7 but now when I choose "duplicate display" from the side menu popup the tv goes blank as if Ive unplugged the hdmi. All 3 of the remaining display options work including the extend display and tv only setting so its not a cable issue. Laptop model is XPS 17 L702X. Now when I used to do it in win 7 sometimes it wouldnt autodetect it so I would have to right click desktop, open invidia up and click rigorous display detect or something like that and then laptop screen would blink and make the beep noise like when hdmi cable got connected. Now in the invida panel it just simply wont allow mirroring, nothing happens when I right click on the display box that would normally show 1 and a smaller box would say 2. I dont get it but Id really like that feature back If its something simple I could do.
I've been running a multi-monitor setup for a while now, with an ASUS VG248QE 144Hz monitor as my main, and one or more spare monitors as secondary displays. I've set the ASUS monitor to 144Hz without issue in the past, while the other monitors stay at 60Hz.
The other night, Windows wanted to update. I figured it was the usual patch session, so I let it do its thing. However, after restarting my computer, I noticed that my ASUS monitor would only operate at 144Hz if it was the only monitor plugged into the system. When I try to set it higher in the Nvidia control panel, it just reverts back to 60Hz after applying changes. I updated my graphics drivers (though I was only one version behind) and even sought a special ASUS driver for the monitor to resolve the issue, but nothing has worked.
Did Windows recently add a forced refresh rate sync between all monitors recently? If so, that really sucks because I only own one 144Hz monitor.
I installed Windows 10 and found some apps did not fit the monitor screen (too big). I went in and changed the monitor resolution to a larger size (windows recommended 1920 x 1080) but I tried something larger, and now the monitor has a black screen with a little box moving around which says "input not supported". Not being able to use that monitor to go in and change it back, I hooked up a flat screen t.v. which worked but Windows only showed the current monitor size (which was smaller than the original monitor.
I tried the monitor on another computer I have also running Windows 10 and it worked fine. It shows the resolution as 1920 x 1080. When I plugged it back into the original computer I get the same plack screen with "input not supported" so I can't change it there. I suspect the issue is with the registry somewhere in Windows 10 on the first computer, but what the problem is. I've been working on this for a whole day now. You can probably tell I'm not well versed in computer technology. I just want my old monitor back (Acer K272HL) and I promise I won't mess around with it again.
I recently got a new monitor, an Eizo EV2750, which Windows only recognizes as a generic PnP monitor.
I've tried connecting it thorugh DisplayPort, HDMI and DVI without any luck. The often mentioned sollution, to unlplug everything and wait 10 minutes, does not work either.
The graphics card seems to read the EDID however, as in nVidia control panel it displays correctly as EV2750. Same thing with other applications, like DisplayCAL which I use as my color management system.
Seems like it's only an issue with Windows. This issue, however, also means that I can't get full functionality from the monitor. For instance, the ambient light sensor does not work (which is typical when Windows doesn't recognize the display properly).
I just installed Windows 10. Now my laptop monitor won't work - only the external monitor. I go to Graphic setting and click on multiple displays, but it states it doesn't see another device only the external monitor. Tried disconnecting the external monitor and rebooting, but the laptop display still doesn't turn on.
Ever since I installed Win10 the monitor has been turning on by itself between 3 and 5 am every night, or 3 minutes after login after a reboot if it is off at the time. Except on days immediately after a noticeable win10 patch. It is turned off physically, not by the system. Only having the system off or unplugging the monitor prevents it from turning on.
I have set my system to check for updates at 10am but that does not seem to affect the problem at all. I have tried looking through the event viewer for items at the time its happening but haven't found a good tool to sort by time.
Everytime I reboot my monitor says Monitor is going to sleep, then logo from Dell then boots, been doing this for a year, I use no sleep functions in power options,
So before windows ten I could play wow, swtor, secret world etc.. on my main monitor and watch netflix on my second monitor with no issues. Well after windows 10 the video in my second monitor lags out when i'm in the game am I playing. Now if i click on the video in the second monitor it plays just fine. Its just when i'm actualy on the game.
This happened sometimes in Windows 8.1 and still happens in Windows 10. I went into settings and changed when to turn off monitor to never and put this computer to sleep to never so why does the monitor turn off after no activity anyway?
1st Q: When using Win 10, Microsoft Edge, I like to take an open tab and drag it to my second monitor. Works great in Internet Explorer but I can't get it to work on Edge.
2d Q: I have a drag a Favorite to be in my Favorites Bar but visible across the top? Right now, I have to scroll to the end of the list to get what I want to open. Works great in I.E. where I just drag the Fav right across the top so it's visible.
Basically, after installing windows 10 I turn on the computer, and it works. But my TV which I run through HDMI to my computer shows and says "no signal". SIDE NOTE: when I turn on my computer my computer runs awfully quiet. For a few seconds I hear something get loud but then it dies down.
Although my monitor is not displaying anything I can hear fans running, DVD Rom clicking, power supply both lights on. It was working good yesterday,suddenly this morning I started my PC all I can see is a blank screen.
my window 10 will not recognize that I have 4 monitors hooked up to my pc.. it only sees one monitor only while if I have window 7 it sees all the monitors ..I dont know which setting to activate for window 10 to see my 4 monitors..
OK, after I installed windows 10 my pc rebooted. After the reboot my monitor went to sleep and there was nothing on the screen, my monitor was on sleep mode for about 30 minutes and then a screen finally poped up at 35% windows 10 installation thingee. And at 84% my monitor went to sleep again and BTW I couldn't wake it up. I waited for more than an hour but still my monitor was on sleep mode. Nothing was working. I then held down the power button, my pc turned off and I turned it on again. It still wouldn't load anything on my monitor.My pc is on everything works but there's no signal on the monitor.
I've installed the latest insider on my desktop as it works fine on the netbook, and now the screen turns off after the boot screen, the computer doesn't hang and seems to show signs of working (HDD light flashing). The video card is OK. Once the screen came up after plugging a USB drive, and once the computer booted normally with screen, but now it doesn't.
