    Why no output on VGA monitor with Ryzen 2200G/ASUS PRIME A320 M-K?

    androidmarshmallow

      I've bought recently a computer with Ryzen 2200G APU and ASUS PRIME A320 M-K motherboard.

      I only had a VGA monitor, this motherboard has a VGA port, so at first glance, even at the store they assumed it would work fine.

       

      When I got home and first turned on the PC, disappointment . No image at all on the VGA monitor.

       

      I checked online I already had the latest BIOS installed.

       

      I tried connecting through a HDMI cable to a TV, only then I got image and could access the BIOS, start to install the operating system.

       

      Some days later, in Windows 10, I still had the HDMI TV as 1st monitor, I connected the VGA monitor to the VGA port as 2nd monitor, surprise surprise , I finally managed to get output on the VGA monitor, which told me it works but only in Windows, for some reason, when I rebooted, outside Windows, I couldn't see anything via VGA, only through HDMI.

       

      Is it a motherboard issue (ASUS), or processor issue (AMD)? I've contacted both companies, AMD told me it is recommended to use digital connections such as HDMI, they said nothing about VGA , which leads me to assume AMD didn't worry about full VGA support (since it tends to disappear in the near future), hence why it doesn't always work. I'd still like to know the technical explanation for this, to be better informed.

          Officially AMD, nVidia, Intel, and other companies terminated support for VGA over 3 years ago, so your question needs to be directed to ASUS.

           

          Leading PC Companies Move to All Digital Display Technology, Phasing out Analog

           

          SANTA CLARA, Calif., Dec. 8, 2010 – AMD, Dell, Intel Corporation, Lenovo, Samsung Electronics LCD Business and LG Display today announced intentions to accelerate adoption of scalable and lower power digital interfaces such as DisplayPort and High-Definition Multimedia Interface® (HDMI) into the PC.

           

          Intel and AMD expect that analog display outputs such as Video Graphics Array (VGA) and the low voltage differential signaling technology (LVDS) panel interface would no longer be supported in their product lines by 2015. HDMI has increasingly been included in new PCs for easy connection to consumer electronics devices. DisplayPort is expected to become the single PC digital display output for embedded flat panels, PC monitors and projectors.

           

          DisplayPort and HDMI allow for slimmer laptop designs, and support higher resolutions with deeper color than VGA – a technology which is more than 20 years old. Additionally, as laptops get smaller and their embedded flat panel resolutions increase for more immersive experiences, the power advantages, bi-directional communications and design efficiency benefits of DisplayPort make it a superior choice over LVDS, the previous standard for LCD panel inputs.

           

          Intel plans to end support of LVDS in 2013 and VGA in 2015 in its PC client processors and chipsets.

           

          "Modern digital display interfaces like DisplayPort and HDMI enhance the consumer visual PC experience by immersing them with higher resolutions and deeper colors -- all at lower power -- to enhance battery life for laptops," said Eric Mentzer, Intel's vice president of Strategy, Planning and Operations for the Visual and Parallel Computing Group. "By moving to these new interfaces, Intel is able to focus investment on new innovations to enhance the PC experience rather than having to solve challenges of supporting legacy analog interfaces on our latest silicon process technology and products."

           

          AMD plans to begin phasing out legacy interfaces, starting with the removal of native LVDS output from most products in 2013. The company also plans to remove native VGA output starting in 2013, with expansion to all AMD products by 2015. This would mean DVI-I support will be eliminated in the same timeframe.

           

          "Displays and display standards are rapidly evolving, with new features such as multi-display support, stereoscopic 3-D, higher resolutions and increased color depth quickly moving from early adopter and niche usage to mainstream application," said Eric Demers, AMD's chief technology officer, Graphics Division. "Legacy interfaces such as VGA, DVI and LVDS have not kept pace, and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward. In our opinion, DisplayPort 1.2 is the future interface for PC monitors, along with HDMI 1.4a for TV connectivity."

           

          While the large installed base of existing VGA monitors and projectors will likely keep VGA on PC back panels beyond 2015, leading PC makers are in strong support of this transition. The DisplayPort connector interface provides backwards and forwards compatibility by supporting VGA and DVI output via certified adapters, while also providing new capabilities such as single connector multi-monitor support.

           

          Moving to the latest digital standards like DisplayPort enables customers to preserve backwards compatibility with installed equipment while taking full advantage of the latest advances in display capabilities, configuration options, and features," said Liam Quinn, chief technology officer, Dell Business Client.

           

          "We live in a digital-rich world and display technology must keep up with the explosion of digital content," said George He, chief technology officer, Lenovo. "By transitioning to digital display technologies like Display Port and HDMI customers can not only enjoy a better computing experience, they get more of what's important to them in a laptop: more mobility, simplified design with fewer connectors, and longer battery life."

           

          Leading display panel manufacturers such as Samsung Electronics LCD Business and LG Display also are in strong support of this transition.

           

          Samsung Electronics LCD Business is already supporting this transition with embedded DisplayPort notebook panels, which we have been shipping since March of this year," said Seung-Hwan Moon, vice president of engineering, LCD Business, Samsung Electronics.

           

          "LG Display is fully prepared for this future transition. We already have different sizes of LCD panels with eDP out in the market to fulfill various needs of customers." said Michael Kim, vice president of IT Product Planning Department at LG Display.

           

          The strong value proposition of scalable and low power digital display interfaces for PC users coupled with industry innovation around these interfaces should accelerate overall adoption of the newer display technologies for PCs.

              Interesting article, confirms my suspicions until now. My question should be directed at ASUS? Actually, judging from that article, it seems AMD terminated support for VGA 3 years ago, so my combination of Ryzen 3 2200G/ASUS PRIME A320 M-K didn't always work with a VGA monitor because of AMD.

               

              As far as ASUS is concerned, I suppose the ASUS PRIME A320 M-K still works fine through VGA with other processors from other manufacturers. In fact, my ASUS motherboard has a VGA port, which seems to indicate they still support VGA, or else why would they add the VGA port to their motherboard?

               

              I was not the only one asking this question. In the past days, doing a few searches about this issue, I've found on forums online other people asking if the Ryzen 3 or Ryzen 5 APUs and similar motherboards will work through VGA. Believe me (you can confirm yourself), I've seen many replies from other people saying of course it will work with VGA, which is a wrong information.

                  Ryzen 3 1200 or 2200G? Does your motherboard have a VGA port? If so, have you tried connecting the VGA monitor directly to the motherboard? Did it work?

                   

                  I've thought about getting an adapter to solve my vga connectivity problem, maybe some adapters could solve my issue, I just didn't like the idea very much. From what I've read online, it can be quite a gamble, people claim some adapters work, others just don't, so if yours worked, more power to you. If I understood correctly, your R9 380 has HDMI and DVI ports, your motherboard has VGA and HDMI port and you have a VGA monitor. You have a VGA to DVI adapter so you can connect your VGA monitor to your R3 380. Interesting to know different setups
