Two GPUs from various suppliers leading to complications
Two GPUs from various suppliers leading to complications
The GPU only provides a VGA connection, which isn't very practical.
The specifications for the Radeon HD 6570 lack a DP port, which seems unusual... It would be wise to stick with cards from the same manufacturer to avoid driver conflicts. You might consider models like the Quadro K2000 or K4000—they offer two DP and one DVI-D port and are reasonably affordable on eBay.
I identified the exact Radeon model I purchased. I searched online for advice, hoping someone could offer guidance without suggesting a replacement from the same manufacturer. I’m looking for affordable options right now.
I understand your perspective. It’s worth considering alternatives to removing a card.
Sure, I understand. I’ll wait until I have sufficient funds to begin constructing a new project.
The daisy chaining limit is determined by the number of monitors the card can handle, usually four. For typical consumer cards, you also require displays that support MST or a compatible hub.
The specific numbers aren't fixed, we must set the target. Current port restrictions? Data throughput limits usually take priority. On my RX6800 GPU I don’t see a strict cap on screen count, just per-port data limits. For my GPU, 1.4a DP port supports about 26 Gbps, which would let me handle around 6.5 1080p screens at 60Hz. Doubling for two ports gives roughly 12 screens if each port has its own limit. Based on my knowledge, if the rate is per port, I could fit 12 at 1080p. Some sources suggest a software cap of four monitors for NVIDIA cards, meaning a Quadro or AMD solution might be needed. Most people online agree on 4 monitors—possibly 5 at 1050p or up to 6 if daisy chaining is allowed. The monitor’s ability to handle a daisy chain also matters.
There are cards with more than four ports, such as 3xDP or 2xHDMI, but only four can be used simultaneously. It seems possible to connect more than four monitors by linking them together. Reddit suggests your card supports up to six displays at once. Each port can handle around 26 Gbps, so using both at full speed together is feasible. There appears to be a maximum limit elsewhere. The underlying technology for each port likely caps performance at about 52 Gbps when two are active. For higher numbers you’d need specialized business-grade cards.
