after install gtx 1050ti card, using tightvnc windows open with junk

I just got a new video card, an evga gtx 1050ti. I used to use the built in graphics of my core i5 4590s.

I use tightvnc to remote to this system on my lan. Now, when I open windows I see a pixelated junk window (before the true window next appears) that flashes for an instant. Then it displays the window contents correctly. It never did this when I was using the built in graphics on the core i5 chip.

When running direct (i.e. not over tightvnc), I don't see this effect. Other than this, my new card seems to work just fine.

I tried to contact tightvnc, but to no avail.

Has anyone ever seen this before?

What PCIe port did you install the GPU on? Did you install the driver/software for the GPU? Have you disabled your onboard GPU in the BIOS? Have you set your PCIe slot as the default GPU?

It might be that GPU you got....it's a low end card. What is the make/model of your CPU...to compare your onboard GPU vs the GTX 1050 Ti.

my cpu is a corei5 4590s and it comes with intel hd graphics 4600

Although this is a low end graphics card, it's many times faster than the built in, so I want to keep using it.

What I'm finding is that the problem only occurs on windows that open immediately, i.e. no animations. For example, opening a cmd window, or notepad, these windows sort of zoom into place and I don't see the problem. On the other hand, firefox and sysinternals procexplorer windows just flash onto the screen, i.e. no animations, and these windows show the problem. If I minimize and un-minimize firefox, it zooms back and doesn't show the junk problem.

Again, if I connect directly to a monitor I don't see the problem. Only using tightvnc. I've tweaked every setting in tightvnc with no luck.

The problem is not a showstopper; it's just so ugly and annoying.

TightVNC was used at my previous place of work, and it would do this all the time. We never really looked into it. Have you tried looking at your color depth, even if it corrects itself almost immediately? Have you deactivated Hardware Acceleration?

As for the Nvidia 1050Ti it's not that much of a low end card when you look at what most people currently run.

Thanks for letting me know that. However, I also noticed that the card would cause my audio to buzz, especially when I would scroll a webpage. I've since returned the card.

I got the card to play a few games and see if programs like handbrake would run faster. It didn't do much of anything for handbrake as it was not using the gpu more than 10% anyway.

With the card returned, I've ordered the fastest i7 cpu I can run on my board, a 4790k. If that doesn't help, I might revisit a gpu, possibly a different brand or an amd card.

This motherboard is very low quality for a 4790 k.

It has only 3 phases for cpu and 2 smd per phase.

above is a similar one with 3 phases from gigabyte wich they found that at x264 video encoding for 6 min at stock speed the cpu throttles because of the mofset temps.

So in your situation i will not buy a gpu but a new motherboard.

I'm afraid you've gone beyond my understanding of MB details. I tracked down an English version of that link, and it's about a different MB than mine.

If you mean I can't overclock it, then that's not a problem. I don't think my board even supports overclocking of K cpus. However, the price I got for the k version was within $10 of the non K and it should give me 4.0 ghz out of the box - a bit faster than the non-k versions. That plus hyperthreading should help.

This cpu chip is listed as a supported chip for my board. Only testing will tell if it works. As long as I don't break the cooler clips changing out the cpu , I shouldn't get into too much trouble. I do have a decent cooler, not the stock intel one.

If I were going to get a new MB, I'd probably go for a ryzen with lots more cores - that would likely help the most with handbrake. But I'm going to have to wait a few years on that.

There aren't really any differences between K and non-K processors. The only difference is the fact that you can overclock the K version.
