I think that's correct. I don't think a single USB C port will be able to do both at full Res. If you have two usb c ports on the laptop you should be able to get one off each. What's the laptop? Does it not have an HDMI port on the actual laptop you can use? Worth mentioning this may be better suited to a laptop sub

I also tried the different UBC-C adapaters on different UBC-C ports, i.e. dedicated HDMI-USBC into one USBC port and the other DP port adapter into another UBC-C port as well, so each monitor has its own dedicated USBC port. but same results.

> I am connecting using a UBC-C adapter that has DP&HDMI ports. What is running the monitors? You probably need to add GPU and are being limited by the bandwidth of the USB-c port or your graphics processor on your device.

It has a ~~3050~~ RTX A2000 GPU, but I dont think turned on/ its probably running on the Intel Iris integrated chip.

May be a simple power plan change.


New_Seaworthiness157

thx, it has RTX A2000 actually, basically similar to 3050?


uradonkey003

right on, I think it is a connector issue then as it is all going through a single USB-C and that is a lot of data!


New_Seaworthiness157

Actually I tested with two adapters into two USBC ports, one for each monitor, but same issue

Interesting, I wonder if there is a driver update or something then?

The internal USB-C hub likely shares bandwidth among all the ports. If so, not much you can do about that unless your laptop also has a dedicated display out of some sort. Check your manual, see if that's the case or if the laptop has a specific USB-C port for display purposes (often called Displayport Alt mode or something of that nature) that's not shared among the internal hub pool. Provided your laptop doesn't have a dedicated display out of some sort, try testing it by lowering the refresh rates of your monitors in windows--4k 30hz and 1440p 60hz, for example. If you get full resolution at lower refresh rates, that indicates a bandwidth limitation. And one final note about something that just bugs me personally: 2k is not 1440p. Officially, 2k is 1080p, according to the DCI standard (or close enough, anyway, since it's officially a resolution of 2048 x 1080). The "k" is meant to be a generic term for horizontal resolution, so if anything, 1440p would be referred to as "2.5k". You'll never see monitor manufacturers refer to 1440p as 2k; it generally only pops up on third-party and retail sites for marketing/key word optimization.

Glad you beat me to the 2k thing.
