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 188.8.131.52
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 184.108.40.206 : 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 ?
