To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Great for connecting 4 fixed image displays - eg advertising, shop or window display. Struggles with 1080p video. Causes pciE latency issues with Asio sound cards. FORGET GAMING : 3D performance was about half that of ON-CHIP gpu of a skylake i6600 cpu! Stuggled with scrolling images across 3 monitors.
I have a RTX 3080 in one slot, and this in another slot - the idea was I could add the various chat windows I use for work.
When I move the mouse into the screen that is being driven by this card the mouse pointer gets all jerky and slow - its nearly un-usable. If I'm playing a video on the 710 driven screen - its smooth and perfectly fine, UNTIL I move the mouse into that screen.
This machine is no slouch either - 32 gigs of ram, 9900K CPU, etc etc.
Maybe its really only designed for a system where all the video cards are the same.
This graphics card is very quiet and works well with 1-2 HDMI monitors, for the cost. I replaced my other card that always had a noisy cooling fan since new (also Nvidia). The 4 HDMI ports is done solely to get you to purchase their product over other options on Amazon. Others have complained of issues driving 3 or 4 displays. If I try to use 3 monitors, my i7 Intel computer instantly has a heart attack and freezes up, 100% of the time. This card neither has the processing speed nor memory to properly drive 3-4 displays. I purchased 2 of these graphics cards to drive my 4 monitors. Works fine, except I have 2 less API ports.
