Problema con la Resolución del Monitor al Usar Conversor VGA a HDMI en Manjaro
Espero que se encuentren bien. Me pongo en contacto con ustedes para solicitar asistencia con un problema que estoy experimentando con la configuración de mi monitor en Manjaro. Descripción del Problema: Tengo dos monitores Samsung modelo LS27C36X. Uno está conectado a mi notebook Lenovo V330-14IKB mediante HDMI y funciona perfectamente a una resolución de 1920x1080. El segundo monitor está conectado a través de un adaptador VGA a HDMI. A pesar de mis esfuerzos, no he podido configurar este segundo monitor para que funcione a la resolución deseada de 1920x1080; la resolución máxima que puedo alcanzar es 1024x768.
Issue with Monitor Resolution Using VGA to HDMI Converter on Manjaro
I hope this message finds you well. I am reaching out to request assistance with an issue I am experiencing with my monitor setup on Manjaro.
Problem Description: I have two Samsung LS27C36X monitors. One is connected to my Lenovo V330-14IKB notebook via HDMI and works perfectly at a resolution of 1920x1080. The second monitor is connected through a VGA to HDMI adapter. Despite my efforts, I have been unable to configure this second monitor to operate at the desired resolution of 1920x1080; the maximum resolution I can achieve is 1024x768.
System Specifications:
OS: Manjaro Linux x86_64
Kernel: 6.9.5-1-MANJARO
CPU: Intel i5-8250U (8) @ 3.400GHz
GPU: Intel UHD Graphics 620
Desktop Environment: Plasma 6.0.5
RAM: 8GB (7808MiB)
Steps Taken:
I have updated all graphics and system drivers.
I have attempted to configure the resolution manually using xrandr without success.
I have tried different configurations in X11 files.
Commands and Outputs: Below is the output of the xrandr -q command for your reference:

I would greatly appreciate any guidance or solution you can provide to resolve this issue and enable both monitors to operate at the desired resolution.
VGA connectors do not really support widescreen aspect ratios. So while technically VGA supports up to 2048x1536 (although good luck trying to get this to actually work in practice), I’m guessing that the maximum VGA resolution your monitor - or perhaps the HDMI adapter - supports is 1024x768, which is the highest widely supported VGA resolution.
Realistically, the only way you’re going to get that monitor running at 1080p is to use a native HDMI connection. I don’t believe it’s a Manjaro or even a Linux issue. The hardware simply doesn’t support what you want to do.
Thank you for taking the time to respond to my previous query. I would like to add some additional details and get more guidance on this issue.
New Details:
Recently, I tested my configuration with another distribution, Q4OS, and although I did not reach the full resolution of 1920x1080, I did get a higher resolution than in Manjaro, reaching 1280x720. This suggests that the adapter and monitor hardware may support higher resolution, but it appears that Manjaro has some limitation that prevents achieving higher resolution.
Additional Steps Taken:
I have updated all graphics and system drivers in Manjaro.
I have tried configuring the resolution manually using xrandr and X11 configuration files without success.
I have tested the same hardware with Q4OS and achieved a resolution of 1280x720.

Possible Additional Solutions:
Compare Settings: Are there any Q4OS-specific configuration files that could be facilitating the higher resolution we could replicate in Manjaro?
Force Resolution with Models: Could we try to force resolution in Manjaro using specific models? I’ve tried this before, but any specific suggestions might be helpful.
Drivers and Kernel Configuration: Are there any specific kernel or driver configurations that we could adjust to improve compatibility and resolution support in Manjaro?
Hardware Alternatives: Could it be useful to try a different adapter or some specific hardware that has better compatibility with Manjaro?
I appreciate any additional guidance you can provide to help me resolve this issue so I can use both monitors at the desired resolution.
1280x720 isn’t going to achieve your goal, so I’m not sure it’s that relevant. A VGA connection is not going to drive a monitor at 1920x1080, and your only real solution to achieve this would be to use HDMI, Displayport, or at a minimum dual-link DVI. As to why Manjaro doesn’t have this option, it is likely due to either kernel or mesa versions, neither of which you’ve given information on here. The output of inxi -Faz is always helpful here.
Secondly: if you want to ask ChatGPT or similar for help, feel free to do so. But I wouldn’t bother posting output from an LLM here, and everything after “Possible Additional Solutions” appears to be written by an LLM. It doesn’t even appear that you’ve taken the time to read it before posting here, considering that you’re apparently insisting on using the VGA connector and then in your own post suggest using “Hardware Alternatives.”
Thank you for your response and for pointing out the relevant issues. I understand that 1280x720 is insufficient to achieve my goal and that using a VGA to HDMI adapter may be limiting my ability to reach a resolution of 1920x1080. Below is the additional information requested about my system.
Additional Context: I tested this setup with Q4OS and achieved a resolution of 1280x720, which suggests that the hardware can support more than what I am currently getting on Manjaro, although it does not reach 1920x1080. I understand that using HDMI, Displayport, or at least dual-link DVI would be the ideal solution to achieve 1920x1080, and I am considering these hardware alternatives.
Additional Questions:
Would it be helpful to try a different kernel version or update mesa on Manjaro?
Are there specific configurations I could adjust to improve compatibility and resolution support on Manjaro?
If I decide to switch to a different adapter, are there any specific recommendations to ensure the best compatibility with Manjaro?
I appreciate any further guidance you can provide to help me resolve this issue and use both monitors at the desired resolution.
Again, please read the output of your AI assistant before posting it. In addition to the writing style, you have again posted something with basic contradictions - in the first paragraph you acknowledge that VGA to HDMI adapters will not work, and then in additional questions you ask if switching adapter will fix things. Humans tend to be smarter than this.
There is no way of achieving what you want with a VGA to HDMI adapter. Unless you’re going to post something not written by an AI, this is the end of the discussion.
Not true. My monitor (attached to the other laptop) is running at 1920x1080p @ 60Hz, with a straight VGA cable to the monitor, albeit with no conversion, without any issue.
No problem connecting it to this laptop, either. Both Lenovos, this one’s a T440 and the other is an IdeaPad the model number of which I haven’t a clue. (Labels have long gone and haven’t actually checked).
OK, maybe it’s possible, and I was just cross with AI generated responses (apologies on this - I had to fail a final year student at my job due to this).
Without knowing the adapter being used, I’m not confident we know enough to suggest any fixes. However, I’d say it’s very likely that either the adapter has an issue with 1080p or the cable doesn’t have the signal integrity to support it. I’m not sure why Q4OS supports a higher resolution, but it still isn’t anywhere close to the target so I’m not sure it matters.
From the laptop specs, it looks like the laptop has a USB-C port supporting Alt-mode. I’d suggest that the simplest way of fixing things would be a USB-C to HDMI adapter. This would also deal with any issues that are likely to happen due to the use of VGA at a high resolution, like fuzzyness and crosstalk (which are pretty much inevitable, and part of the reason why I say VGA does not really support these resolutions, because these can cause health issues in some people).
