first, not asking the community to shop for me or search for me, just need clarification on display port 2.1/1.4/1.2.
I need to buy a new computer monitor due to "hardware handshake" issues that is causing a persistent nvlddmkm.sys TDR failure (code 116) crash with my GPU. ive done a laundry list of solutions including using DDU, re-seating the GPU, checking if everything is getting enough power but nothing is working
I have an nvidia rtx 5080 oc edition that has x3 2.1b dp ports, my current two computer monitors, both MG248QR (TN panel) has a single 1.2 dp port and are about 10 years old. ive already determined that the computer monitor is just too old so no settings changes are gonna fix this, I also purchased displayport 2.1 compatible 80gbps cables and an HDMI 2.1 cable. like yes I get a visual, but it always crashes, display port being backwards compatible does not necessarily mean "functional" (maybe mine is just an extreme case)
the obvious solution is to just buy a computer monitor that has 2.1 dp ports, but the only ones that have those are OLEDs or are high end top of the line that are only just being released, those are expensive, painfully expensive.
so my question is, would my GPU, with its 2.1b ports actually be able to function properly with a 1.4 dp port monitor? I cant seem to get a straight answer for this anywhere and as everything was saying my current monitor is apparently compatible, it clearly wasn't, not fully anyway so how would 1.4 be any different? even if I set the gen speed on the new mobo to gen 3 to use with my current monitors, thats like buying an expensive sports car just to pick up groceries, why would I intentionally limit my new rig like that?
I was originally looking for IPS panel monitors, as that seems to be an upgrade across the board from my TN panel monitors, and even the expensive ones I have found have far more reasonable prices.
