This setup used to work just fine (for about 4 months) until I wiped and reinstalled MacOS. The LG 5K is connected on the other side of the laptop. The Ultrasharp is connected to the computer via an adapter that goes from Displayport to Thunderbolt (or USB C). An LG 5K and a Dell Ultrasharp monitor (2560x1440). I have a 13" MacBook Pro Touch Bar (2019) with two displays. If a video driver install becomes horribly corrupted (remote chance but not impossible), a good system backup can be a godsend.1. It can only safely be done thru Add and Remove Programs. For example, as per release notes, GeForce video drivers do not support rollback thru Windows restore, or removal through Device Manager. Under Windows 7, monitor detection is performed by Windows' own CCD (Connecting and Configuring Displays) API, so it could be worth running a check on system file integrity:īefore you look at potentially making any alterations to the system, do you have adequate system backup - any system partition image or similar? Apart from this just being good safe practice for an important computer, it can be useful if something annoying goes wrong during maintenance. Yours is Driver version: 10., latest is 10. There have been a couple of video driver version releases since yours, so you could try the current release if you wish, in case your effect was a bug that's been addressed: However there seems to be no indication of a random video driver update, and MSI link to default GeForce WHQL drivers for their products anyway so there shouldn't be a problem there. And it used to work temporarily before going out, now if I plug it in it just immediately starts doing the connect/disconnect thing.ĭriver updates sourced thru Windows Update can sometimes cause a problem, which was what I wondered about. I also tried only plugging Monitors A B and D in to see if it was a monitor problem, and they all worked fine until I plugged in monitor C. I tried plugging monitor C into port 4 and it worked with no problem, but when I plugged monitor D into Port 3, the problem started again. I have monitors A B and C plugged into ports 1-3, and when I plug monitor D into port 4, the problem starts. For example, my ports are laid out like:ġ being DVI and 2-4 being DisplayPort. I'm able to plug 3 monitors into any configuration of three ports with no problem, but when plugging in a fourth, that's when the problem arises.
It's always a DisplayPort monitor that has the problem. I ran DVI directly to one of the monitors, and used three DisplayPort>DVI adapters to run DVI to the other three. So my graphics card has 5 outputs: 1 DVI out, 3 DisplayPort outs, and 1 HDMI out (that mirrors the last DP port).
