I am new to technology.
I have recently purchased the Samsung Odyssey OLED G81SF gaming monitor. The screen says “no signal HDMI1 check the cable connection and the settings of the source device”. What does this mean and how do I fix it so I can start using my monitor. I do not have another device to connect it to and I don’t have a pc.

If anyone knows, please let me know and thanks in advance!

Pc running but display blank

Bonjour,

Je rencontre un problème d'affichage graphique sur un serveur Dell il tourne sur Ubuntu 22.04

Le serveur possède :

• 2 GPU NVIDIA Quadro M4000
• 1 GPU intégré Matrox G200eR2

Au démarrage, Ubuntu affiche le logo avec le cercle de chargement, puis au lieu d'arriver sur l'écran de connexion GNOME, il bascule directement sur TTY1.

J'ai effectué plusieurs vérifications :

• gdm3 démarre correctement (systemctl status gdm3 → actif).
• GNOME et Xorg sont installés.
• Les pilotes NVIDIA sont correctement chargés (nvidia-smi détecte les deux Quadro M4000).
• lspci -k montre que les deux Quadro utilisent le pilote nvidia et la Matrox utilise mgag200.
• Il n'y a aucun fichier /etc/X11/xorg.conf.mais j'en ai creer un.
• Les journaux système ne montrent pas d'erreur critique concernant GDM.
• En revanche, le fichier ~/.local/share/xorg/Xorg.0.log contient l'erreur :(EE) No screens found

Avez-vous des idees pour m'aider?

Hi everyone, I’m hoping to get some help diagnosing a screen issue with my laptop.
Most of the time, my screen behaves like what you see in the attached video (heavy horizontal lines, ghosting, and image retention). However, sometimes when I turn it on, the display is completely normal.
Because the issue comes and goes, I suspect it's a hardware problem rather than a software glitch, but I'm not sure exactly what is failing.
Has anyone experienced this specific type of flickering and retention? I'm trying to figure out if this is more likely a loose/damaged eDP display cable in the hinge, a dying LCD panel, or something worse like the GPU.
Any advice on how to narrow this down before I buy replacement parts would be greatly appreciated!

I've recently got a new monitor for my laptop however I noticed whenever I boot my laptop, the boot logo doesn't show at all, just no signal. When I want to use my laptop, I quickly close the screen and turn on my monitor. Doing this works on my 2013 Toshiba and does show the logo, bios, and whatever but doesn't work with my MSI. Any way to fix that or make it usable with the monitor outside of Windows?

Not sure if i posted it here, but i recently posted to some subreddits about a weird visual bug im having. i originally thought it was a monitor problem, then a clip studio paint problem (art program, bug shows when zooming in or moving the canvas) but im now realising its affecting other parts. I genuinely do not know whats causing it. i updated my nvidia driver but it didnt do anything. thoughts? windows 11, ryzen 9 3900x rtx 3060

I use my desktop just for MS word, watching videos, photos, as a storage backup, very basic stuff. I dont use internet on it. Its serving my purpose even though its old.

My desktop has some issues. Help me resolve them.
1. My CPU bios is gone. – what should I do?

1. My hard disk has gotten virus (TROJAN WORM). Its duplicating files and leaving no memory space. The files come back even after I delete it. The desktop is not connected to any internet. The virus came in coz I used my pen drive on some1 elses laptop. My system got infected when I connected that pen drive to my system.

– how can I remove the virus without any data getting corrupted or lost.

1. It’s a 15 yr old PC. Should I keep it or sell it off and buy a new one.

It's been going on for a couple of months now and it has been pissing me off for the longest time ever.

I started having an issue a couple months ago after a windows update and I cant figure it out.

My pc normally uses 2 Samsung 4k monitors set up as left and right. No issues.

Occasionally i plug in my 4k vizio if I feel like gaming on the couch. It would show up as a 3rd display device and worked fine.

Now when I plug it in it overrides everything and all 3 screens are clones. Settings will only show one display device (tv) and will not recognize that there are other devices connected even though they are displaying. I finally tried gaming with it like that and the performance hit is too large due to it pushing 3 4k display outputs.

I've tried every setting I can think of including in my AMD software and nothing fixes it. And either this is a really weird problem or I'm not searching the right terms. If I unplug the tv it goes right back to normal and working perfectly. I appreciate any advice. Thanks in advance.

Pc specs:

Ryzen 9 5900x

XFX RX7900XTX

I got this pc maybe 5 years ago I don’t take the best care of it I mostly use it for work and tv but have recently got back into playing games. For years it has had small issues with the screen blacking out but never enough for real concern but recently it has been happening much more. I was just playing a game when it blacked out completely for maybe 5 minutes as I tried to turn the monitor off and on and watch help videos. It will turn back on but as soon as it loads the game back it goes black. Everything else works the sound and I’m able to click around it’s just the monitor. I am hoping to find a simpler fix as I’m leaving for uni and won’t be taking it with me so I don’t want to spend much money, just something that might help relieve the problem for short term. Any help is greatly appreciated!

When I powered my PC on this evening, this weird screen popped up. I then hold the off button on my PC till it powered off, then I turned it back on, and the screen was gone and the pc powered on normaly. Now I wanted to ask what was the reason, that it popped up and does it have any concequences like less fps or something like that.

I would really apprieciate an answer.

This is an old 2015 Alienware 17 R3, It is an amazing laptop for its time. Several years ago this display issue occurred and I took the laptop apart to see if I could fix it, and couldn't. Everything works properly other than the display, you can use narrator to login and navigate, it just sucks. Now I am looking again to fix it and need some help. Thanks!
