Monitor Cables

If you have a discrete GPU then you need to plug your monitor cable into the graphics card, not the motherboard. This can be found on the Quick Start Guide which was emailed to you, or you can download it with the /tag guide command.

zenith ibex Aug 3, 2024, 2:34 PM

#

I mean, you have 4 sticks at high ish speeds it literally could just be failing memory training every once in a while

fallen knot Aug 3, 2024, 2:35 PM

and I reinstalled Windows 11 Home ed about a week ago

zenith ibex Aug 3, 2024, 2:35 PM

#

Yeah

fallen knot Aug 3, 2024, 2:36 PM

#

it did cause more issues as I reinstalled it from the cloud but after doing it on USB it's fine

zenith ibex Aug 3, 2024, 2:36 PM

#

oh

#

so you load into windows with a cursor and a black screen?

fallen knot Aug 3, 2024, 2:39 PM

#

no cursor, just both black screens

zenith ibex Aug 3, 2024, 2:44 PM

#

I had an old computer that did just that

#

I wouldn't worry about it if you can get it to boot after a restart tbh

fallen knot Aug 3, 2024, 4:22 PM

#

I have just made sure my cables are in correctly and it booted up with no issue. I've also had this PC since 11/12/2023.

zenith ibex Aug 3, 2024, 4:28 PM

#

Yeah

fallen knot Aug 3, 2024, 4:35 PM

#

I'll see what happens for the rest of the week.

fallen knot Aug 5, 2024, 4:27 PM

#

And it happened again.... Both screens are on and are black and I just heard the fans increase in speed a bit. I'm not sure if it made a post beep sound, so next time I'll pay more attention.

fallen knot Aug 6, 2024, 12:22 PM

#

PC post beep then splash screen for MOBO then black screens. Turning on and off my screens I'm then able to login. What could be the issue?

zenith ibex Aug 6, 2024, 12:45 PM

#

fallen knot PC post beep then splash screen for MOBO then black screens. Turning on and off ...

your windows install probably

fallen knot Aug 6, 2024, 12:48 PM

#

zenith ibex your windows install probably

Ugh and I reinstalled it about a week ago....

fallen knot Aug 8, 2024, 4:12 PM

#

I have just reinstalled the most recent update and will see how things go.

fallen knot Aug 9, 2024, 7:02 PM

#

nope...same issue...I really can't be bothered at the moment to re-install Windows 11 AGAIN! 😫

zenith ibex Aug 9, 2024, 7:02 PM

#

Damn

#

I mean tbh its ok if it works

#

just a system qwerk

fallen knot Aug 9, 2024, 7:04 PM

#

What I'll do tomorrow is make sure that I've not disrupted any cables from the last time I opened my PC to clean it.

May also be worth double checking your graphics card drivers are up to date. Do you also see any LEDs lit up here when it black screens - if so, which?

fallen knot Aug 10, 2024, 2:17 PM

#

First LED, then second LED then they go off and my monitors are on (for now) I updated my drivers via AMD adrenalin and are up-to-date.

#

I'm currently in safe mode using DDU, restarted my PC and now going to reinstall my GPU drive.

rancid fable Aug 10, 2024, 4:07 PM

#

Yeah it's normal for some of them to come on as your PC boots, though if any of them start hanging then that normally indicates a problem
DDU was going to be my next suggestion so see how that goes!

fallen knot Aug 10, 2024, 4:36 PM

#

I'll keep you updated

fallen knot Aug 11, 2024, 10:22 AM

#

And it happened again.....

After removing and re-inserting both DP cables, I'm still having the same issue. When I turned on and off my monitors, this time the resolution was wrong (very small icons etc). I logged out then back in and it was back to normal. What I plan to do in a few days, is only have my main monitor connected for a week and see what happens then repeat the same thing with my other monitor.

So far from my testing, from just using my main monitor, I have no issues. Today, I plan to try with my second monitor for a few days.

fallen knot Aug 19, 2024, 8:33 PM

#

Ok so I suspect that the DisplayPort to HDMI might be failing as it went black twice. Once on idle and didn't come back on (even with turning the monitor on and off) and again during a restart.

#

I've just ordered a new cable and will update on the situation when it arrives and install it.

golden vector Aug 19, 2024, 8:44 PM

#

Check the specs of your monitor and gpu for DisplayPort version

fallen knot Aug 19, 2024, 8:58 PM

#

Lenovo L22e-30 - HDMI 1.4

#

AMD Radeon RX 7800 XT has up to three DisplayPort 2.1 outputs and a single HDMI 2.1a port.

#

this is the cable I just ordered https://www.amazon.co.uk/gp/product/B015OW3P1O/ref=ppx_od_dt_b_slice_asin_title

Amazon Basics DisplayPort to HDMI Display Cable, Uni-Directional, 4...

#

its the same one that I am currently using

#

and I've had it for about 3 years.

When I switched to DP from HDMI many moons ago I had issues. It was mainly due to cable specs and monitor support. I still have issues today with the latest specs for compatible cables and new monitors. DP can be a pain in the ass.

fallen knot Aug 19, 2024, 9:06 PM

#

the reason I've got a DP cable to HDMI is because my Oculus Rift CVI is occupying the HDMI port.

golden vector Aug 19, 2024, 9:06 PM

#

ahh

#

that "could" be the issue... it may be prioritising the Oculus

fallen knot Aug 19, 2024, 9:08 PM

#

yeah, that's the issue, I'm not going to remove and put back in the HDMI port for my headset over and over again when I want to use my second monitor as well as exhausting the HDMI port.

#

I've not had this issue before even when I had Windows 10.

#

and it just happend after many months having my current PC

golden vector Aug 19, 2024, 9:08 PM

#

I agree, its shite to have to deal with that... but does it happen when the headset is not connected?

fallen knot Aug 19, 2024, 9:09 PM

#

Good question....I've not tried that...

golden vector Aug 19, 2024, 9:09 PM

#

at the end of the day the Oculus is a display so

fallen knot Aug 19, 2024, 9:10 PM

#

I'll just disconnect my headset now and see what happens over a period of days.

golden vector Aug 19, 2024, 9:11 PM

#

I leave my PC on 24/7 (work reasons) and I have to close all my windows on all my monitors (all DP) otherwise they all appear on the first monitor I switch on... DP is great for throughput and such but the WIndows suppoort is shite

#

Even now, I have a small sensor panel display (800x480) that is HDMI and apps will open on that screen

hope you find a "fix"

Same here. If worse come to worse, I'll just get a new cable for my monitor
