What would you recommend as the best types of cables to connect devices such as PCs and laptops to the iiyama 86" TE8668MIS-B1AG Interactive Display to get the best video quality


We have a conference/ brainstorming room with an Iiyama display mounted on a wall.

We would like to connect devices such as PCs and laptops to this Iiyama display as to allow for multiple devices to display their screen on the Iiyama display.

Here are the technical specifications of iiyama 86" TE8668MIS-B1AG Interactive Display:

I am looking for the best types of cables to connect the following devices to the Iiyama 86" TE8668MIS-B1AG Interactive Display to get the best video quality:
a. Laptop (HP 250 G6 Core i7-7500U: https://www.laptopsdirect.ie/hp-250-g6-core-i7-7500u-8gb-256gb-ssd-dvd-rw-15.6-inch-windows-10-professio-1wy37ea/version.asp)
b. PC (Microsoft Surface Studio: https://www.microsoft.com/en-us/surface/devices/surface-studio/tech-specs)
c. Sky Q Mini box
d. Blu Ray Player
e. AVR (Denon AVRX4300H: https://usa.denon.com/us/product/hometheater/receivers/avrx4300h)

Noting that:

1. The Sky Q Mini box and Blue Ray Player are already connected to the AVR.
2. It is for conference/ brainstorming room.
3. There may be visitors laptops - Windows or Mac
4. The Iiyama display is wall mounted

What would you recommend as the best types of cables to connect the above devices to the iiyama 86" TE8668MIS-B1AG Interactive Display to get the best video quality?

So, from the general perspective, you should use at least the highest standard what is supported by the devices... As your Iiyama is  the device what should be connected, this devices defines the minimum specs for the cabeling...
I would always prefer digital signals over analog signals.
You device supports HDMI 2.0 (digital) for video and VGA (analog), and also stated HDMI3 for control...
For the last one (HDMI 3) , I can not really find specs.
As the prices for cables are not so different, select a cable which has the highest compatibility... You find them compatible with HDMI x.x version (not official anymore as for some versions, the cable doesn't paly a role), but more official is HDMI High Speed or HDMI High speed with Ethernet (additional Ethernet connected wires, but can not see, that your display support this...).
As longer the cable (default spec is 10m) as better the shielding of the cable should be.

From my experience, I would offer an additional VGA cable as well as you said that different computers what to connect and not every computer has a HDMI port....

Thank you Bembi for your informative suggestion.

There seems to be one display port and one HDMI 2 port.

I did some research and found that apparently HDMI is better for TVs and display port would be better for PCs to monitors if they support this type of connection.

The Iiyama is a display which will be connected to our Sky box therefore making it a TV/monitor.

I had planned to maybe do the following:

- Connect Surface Studio to Iiyama display via Mini DisplayPort to DisplayPort cable
- Connect AVR to Iiyama display via HDMI 2 port and using HDMI cable, as Sky box and Blu- ray player are connected to AVR
- Connect other devices to the Iiyama display via wireless or if wired, I was thinking of using VGA cable or HDMI cables to remaining ports

Would my plan work or is there a better way to connect these devices to the Iiyama display for the best video and picture quality?

Lets say, HDMI provides (possibly, dependent from the standard) more functionality...
Yes the display port is a digital port as well and a direct digital connection for displays, it is a different cable and the specified maximum length is 5m, not sure if it is enough for a presentation room.

Yes, and you stated another limitation, the number of ports....
You have 1 HDMI 2.0 Ports and 2 HDMI 1.3 ports...

The surface is a high resolution device and should be either connected to HDMI2 or DP (if the cable length is enough)
Normal laptops (even yours) has standard HD resolution, which can be connected either by a good VGA cable or you can use one of the HDMI 1.3 connectors, which supports more than the device can show.
The AVR depends...
If the HDMI 2.0 is free, use it....

As the AVR is transferring Sky (TV) as well as Blue Ray (possibly also TV) and the device also delivers TV, you should keep in mind, that most of TV formats are limited to HDTV what is 1080p. Al real advantage you only have, if the AVR really delivers higher resolutions. And this also depends from the production format of the film. So even i.e. a blue Ray disk supports more than HDTV, is doesn't mean that the material on it is produced in that format.

I know from a TV broadcast company (a earlier customer from me) that they announced HD nevertheless they didn't had a single production produced in HD. If you want to really produce higher resolution, the whole technic chain from the camera though all the stages of production has to support this format. Otherwise it is just an illusion. Also, moving from SD to HDTV makes the files 4 times larger, the same for all the subsequent formats.

This just to say that connecting your AVR to HDMI 2.0 is more for the future use than the expectation to get a better quality for TV at the moment.  HDMI 1.3 support the current HDTC format, HDMI 1.4 introduced 1920×1080 and 4K / 3D is introduced with HDMI 2.0.
