what's the max display resolution support by ESX?

[dingding]

a customer have AutoCAD software run on VM, so they want to know the maximum display resolution supported by ESX.

Does it depends on the Physical machine, or OS type of VM?

Are you wanting to run it using the Virtual Center console, or through an RDP session (in a VDI-like envrionment.)

If you run an RDP session in full-screen mode, it will adopt whatever resolution the client device supports. Although, you may want to consider how precise the mouse resolution and response time will be over an RDP link.

Are they running AutoCAD via VDI?

How does this work for them?

As the other posters have noted, the "maximum display resolution" may actually depend on how you're accessing the guest's display. When you use RDP to talk to a Windows guest, you actually connect through and activate an RDP virtual display adapter in the guest which is completely independent of the VMware virtual video card - it has its own framebuffer and supports very large resolutions.

As for the VI Client console/VMware virtual video card, the answer is still "it depends". The default VRAM size in ESX guests is only 4MB which is only enough for about 1152x864x32bpp. You can increase the VRAM size up to (I believe, on ESX,) 64MB, by setting the svga.vramSize parameter in the VM config file to the desired number of bytes.

The reason for the low default value is because VMware's virtual SVGA device VRAM accounts for device overhead memory which cannot be swapped and thus increases the memory pressure on the machine.

I also ask WYSE the question, they say if using thin client, it depends on the thin client device.
