ivms-4200 grid view pixelling

Postby azurtem » Tue Sep 12, 2017 8:40 am

Hi

I recently installed a client PC (Lenovo M900 Win7 64bits i7 6700 3.4GHz 8GB RAM, 256GB SSD), upon which we are running iVMS-4200 2.6.2.6

The client complained about a visual issue in which there seems to be a 'pixelling' effect on each camera thumbnail in the main grid view

Having seen the client's screen I can attest that the thumbnails in the main grid view are affected by 'flashing pixels' . All thumbnails are affected, one at a time. It is as if iVMS-4200 is sweeping through all the thumbnails.

All streams in the grid view are set as sub/secondary stream views

I downgraded iVMS-4200 to version 2.6.1.6 : same result.
Changed screens : no difference

Updates bios, chipset, LAN driver : no improvement

The Intel HD 530 graphics driver seems to be already up to date

Other computers running iVMS-4200 on the same LAN are not affected by this issue

Any ideas ?

thanks
yann
