Nvidia 10 series won't be supported soon. Is Upgrading a GPU safe?

Clokwork

I am looking to upgrade my PC and have come down to the dreaded GPU decision. If I keep the same reliable 8 bit only monitor, should I be safe with upgrading to a 40 or 50 series card? Or a current AMD card?

1. rtx30+ dont work for me in any combinations

rtx2070s a bit less strainy than rtx2080s

gtx1060 with 2020y drivers (upto 460 version) - okay

2. z390 less strainy than z690

simplex That's what's scary for me. I wonder what it is with the newer cards that cause strain. Did you use these newer cards with the same Monitor or did you upgrade that as well?

The reason I ask is my display is 8 bit only. Does not support HDR. If that's the case, I'm wondering what the GPU can do to cause more harm. To my knowledge:

The monitor controls the brightness method, so I'm hoping I don't have to be worried about PWM.
Since my monitor maxes out at 8 bit color, I don't believe it supports any color space above RGB. (No FRC)

I'm at a loss.

Yes, same FHD 60hz benq bl2420z (I have 2 pcs) and xiaomi mi 27 2k 165hz

Benq is 6+FRC (I checked with slow video, when all webpages told it 8-bit), xiaomi is ?8-bit? but also accepted 10-bit input

I also had z390+9600k (2pcs), z690+12600k (2pcs), 3080ti, 3080, 2080s, 2070s, 1060

After all I sold z690 and rtx30. rtx20 also strain but much more lower. After getting strain with amd 8845hs/780m and no strain with 13700h/iris xe, I suppose those GPU use internal temporal-blend when render images, which cause chaotic pixel flickering (in additional to monitor's FRC + pixel invertion). I mean, you can use usb switch with HDMI output and still get strain, cos "flickering" includes in signal

simplex I wonder if using an 8 bit monitor that only supports 16M colors would help your situation. with 6bit + FRC, there is temporal dithering (which you already know of course). If the Xiaomi accepts 10 bit input, I bet it supports a larger color space and/or HDR. This might tell me that it also supports FRC natively.

Clokwork using an 8 bit monitor

I am not sure if 8-bit monitors exists. All another 2k 75hz monitors I tried were also 6+FRC. Moreover (benq which is okay) have 2 types of FRC : static ditheting + dynamic. Static could be seen in 6-bit input, and dynamic adds in 8-bit input.

If I am not mistaken (not engeneer), 6-bits need 64 voltage values of transistor for each subpixel, to achieve 64x64x64 = 262k of colors. When 8-bit need 256 voltage steps, economically it 2..4 times more price.

I am wonder if real 8-bit or real 10-bit exists

simplex check out the GW2790T | 27" 1080p FHD. Im pretty sure it’s an 8 bit monitor due to the native color space.

There is some validity to your concern. As I've discussed on this forum before, at least in the past most (if not all) 1080p IPS panels used FRC, whereas before even then there were (at least some) good 1920x1200 IPS panels that were native 8-bit.

All wepages inform bl2420z is 8-bit but only in panel datasheet I found one note: keeping 8-bit input it send 6-bit data into RGB matrix. Then I matched this with slow video recording and detect 2 types of FRC used

To conclude:

1) you need a monitor with its FRC/pixel inversion will "not interfere" with dithering/blending from the GPU

2) as I mention in last threads, even app version (not only OS) can bring ?dithering? (android twitch app 7.00 is okay while 12.0 or 13.0 gives me strain - they rework interface and brings something new). This point is, even good device can become bad

3) this point comes from 2nd. The best way - to ask developers for checkbox to disable dithering in software (apps, operational systems) and in hardware (GPUs).

Watching linux core code, I found devs hardcode dithering types depending on output signals and monitor's capability

For example, "disable HW overlay" option in android 14+ dev menu, and Chrome flags to force GPU render, eliminate strain (not sure, need to check in many devices)

simplex Chrome flags to force GPU render

do you mean force software rendering (aka disabling GPU)?

because typically "forcing -no- GPU render" leads to improvements for me, not "forcing GPU render" as you're saying

simplex

DisplaysShouldNotBeTVs do you mean force software rendering

Nope, force GPU instead of CPU

Override software rendering list = enable

GPU rasterization = enable
