HD Graphics 520 ultrawide monitor compatibility

[Jay343]

Hello,, I have a Lenovo Yoga 300 with integrated Intel HD Graphics 520. Lenovo does not provide any detailed monitor compatibility for this laptop, but the Intel specs indicate that the max resolution is 4096 x 2304. I've tested this laptop with an LG monitor running at 3880 X 1600 and it works fine (but only at 74hz refresh) with the Lenovo HDMI usb-c dongle.

My question is will it also work with a monitor running 5120 x 1440? Does the max resolution spec determine the max horizontal and max vertical? In other words, is 4096 the max horizontal, so 5120 is definitely out? Or, does it specify the max number of pixels, i.e. 4096*2304=9,437,184 and 5120*1440=7,372,800, so maybe it will work?

It may be supported... https://www.intel.com/content/www/us/en/support/articles/000056204/graphics.html

However, there are other things you need to consider... this doesn't depend only on the Graphics controller (hd 520)... the video input type, cables, and specs "oficially supported" by the computer can alter/set different specs...

For instance... I have a Lenovo laptop with 11th Gen and Iris Xe Graphics... despite the CPU-GPU supports HDMI 2.0, Lenovo decided to put an HDMI 1.4 port in this laptop... ( I don't understand why they do that...). The DP connection on the CPU supports 8K, but Lenovo "limited" the Display Port connectivity to 4K 60hz...

A friend has another laptop with 8th gen CPU... despite the CPU supports 4K 30hz, they limited the HDMI 1.4 port to a max resolution 1080p... (again, I don't know why they do that)

I understand Lenovo doesn't provide you with monitor compatibility... but I would suggest you ask them whether the system supports or not that resolution in their video inputs... (e.g.: Intel may say, yes we do support that, but Lenovo may say we don't...)

Thanks! That's very good info. Much appreciated!

Hello Jay343

Thank you for posting on the Intel️® communities. It's recommended that you contact the laptop manufacturer to confirm if this is supported by the laptop and if the monitor is compatible, we can check if your current processor/graphics support it but it could be limited by the motherboard ports and specifications (set by OEM). Please share with us more information:

• Which monitor do you plan to use?
• Which resolution and refresh rate do you plan to use?
• Please explain the connections (ports/cables and if you're using any adapters/converters)
• Is your system up to date? (OS, drivers, BIOS)
• Intel® Graphics Command Center report (with the monitor connected)
  • Open the application 
  • "Support" > "System Diagnostic" > "Generate Report 
• Provide the Intel® System Support Utility (Intel® SSU) results 
  • Download the Intel SSU https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- 
  • Open the application and select "Everything" click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View".  
  • Click on the menu where it says "Summary" to change to "Detailed View".  
  • To save your scan, click on "Next", then "Save".

Thanks for your assistance!

The laptop is a Lenovo Yoga 900-13isk2, I think I bought it in 2016. The only native support for external monitors with this system is via DisplayPort over USB-C.  As I mentioned above, I have a Lenovo USB-C HDMI dongle, and it works well with a 38 in LG monitor running 3840x1600.

I don't have it yet, but I'm considering monitors like the Samsung LC49RG90SSNXZA I'm waiting to see if any Black Friday deals pop up. That will determine which monitor I choose.

The article that Megan referenced seems to indicate that the HD 520 chipset can support 5120x1440, but as she points out, Lenovo could have arbitrarily limited the resolution. I can't find any documentation on the Lenovo yoga 900-13isk2 that indicates that it will or will not work with that resolution, nor can I find anyone in Lenovo's technical support who knows.

I have been looking for a store that has one on display, but no joy. I guess I'll just have to buy one (from a dealer like Amazon or Costco with a generous return policy) and find out!

It is worth noting that the standard DTD (Detailed Timing Descriptor) in the EDID of the monitor is designed for 8 + 4 = 12 bit values and the resolution values in it are limited to 4095:

For the computer's graphics system, it is very important to know the display parameters and according to
with this need for a very long time these data in the form of 128 byte blocks are transmitted
on a special line of the interface of the display when initializing graphics and are stored in the registry in the section

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\DISPLAY ...

for each display separately further in the "Device Parameters" section in the "EDID" variable.
Before Windows 11, only the first block was saved and in Windows 11 and subsequent.
It can also be read by using windows "MSMonitorClass" and special
programs of Intel Corp., AMD Inc., NVIDIA Corp.

This EDID is appropriately handled by the display driver, and for a person it still needs to be decoded into understandable text, for which there are several programs for example edidreader.com (Not secure)

There is also a general library of EDID's in WWW

The "DigitalDisplay.md" file on this page contains a table with manufacturer names, model, display name, resolution

I got it working. Thanks to all for the information! It was enough for me to take a chance on the Samsung Odessey G9 49" monitor (for just under a thousand). It worked immediately with my desktop computer (as expected) which has an NVidia 2080 graphics card, but when I tried it with my Lenovo laptop and the Lenovo usb c HDMI adapter, no joy. It would get information from the monitor, showing it's full resolution of 5120x1440, but it went into a connect/disconnect loop, never actually showing an image on the new monitor. I tried a number of things, like connecting it with the laptop closed, changing the configuration to only use the external monitor, and also updating to the latest Windows 11 Intel graphics drivers. Nothing worked, except one thing. I discovered that if I connected to the laptop from the desktop using Windows Remote Desktop it displayed the full 5120x1440 resolution! So, the graphics interface is indeed capable of generating the required resolution. That gave me some hope that it could work with the right adapter.

I found this adapter with good reviews: Amazon.com: Cable Matters USB C to DisplayPort 1.4 Cable (USB-C to DisplayPort Cable, USB C to DP Cable) Supporting 8K 60Hz in Black 6 ft - Thunderbolt 4 /USB4 /Thunderbolt 3 Compatible with MacBook Pro Dell XPS : Electronics It arrived just a few minutes ago. It works!! When I plugged it in, it immediately showed a full screen image at 3840x1080, which was selected it as the "recommended resolution", but 5120x1440 was selectable, and it works fine.  The new monitor is now running directly off the laptop's built-in graphics via this new usb c to DisplayPort cable at 5120x1440 @ 60hz, while simultaneously displaying a 3200x1800 @ 60hz on the built-in display. 

I'm both amazed and mystified by this cable. It doesn't seem to have any electronics, so the monitor must be natively recognizing the alt mode signal? Anybody know how this works?

[Alx24]

The most important thing regarding such adapters is a very careful choice due to
a minimum of information about them in the specifications and obtaining information from reviews, brand name, launch date.

We are glad to know you found a solution, thank you for taking the time to share this fix, and hopefully, it may help other community members experiencing similar behavior. For higher resolutions is always recommended using high speed cables, no external adapters and checking with OEMs if the resolutions are supported. In some cases the processors can support higher resolutions but they are limited by laptop or OEM desktop specifications.

Since the thread is now solved, we will proceed to close it. Please keep in mind that this thread will no longer be monitored by Intel. Thank you for your understanding.
