4k jerky what is the cause?

I recently got an Acer Predator 4k screen with 144hz and when I tried it, I found that it jerky and has some problems. The funny thing is that it is only when gambling so the screen is not broken because I see the strokes from time to time as he would not quite get over the picture. I'm not stupid I have an 8gb graphics memory, 32gb RAM, new i7 so it should not be. I've used a normal HDMI cable where only high speed draufsteht what brought me the most to smile so I've ordered a new which seems to be designed for 4k: https://www.amazon.de/...07QR22XCP/

I can only try the HDMI cable after the holiday.

My laptop stays cool because I thought maybe it's too much for the laptop and started to cool with a small table fan.

do you have some helpful answers?

4k is immature and total nonsense.

In the field of gaming, you can't expect that much. That works for the fewest games without problems.

Own fault.

I play 4k on the laptop screen and everything is working

I have no idea what you have for a laptop. I can't help you without info's. 8GB vram also tells me nothing - that can be a mobile version of the 1070 - that's simply nothing - that can be synonymous ne rtx2080 - then you go - but 4k you reached with a laptop never 120fps. Can forget - not even in the beginning.

Are you sure that it is a monitor with 4K + 144 Hz? But even the fastest PC is still too slow… And if you have a laptop, then only right…

1) Put the resolution down to Full HD, and then test it again.

2) Which graphics card do you have exactly?

3) And 4K with 144 Hz can only be transmitted via Display Port cable in full power. HDMI may only provide 60 or even 30 Hz at 4K

For a gaming laptop I would honestly only recommend Full HD @ 144 Hz, or WQHD @ 60 Hz.

Because even if your laptop has a RTX 2080 installed, this laptop 2080 is only about half as fast as a desktop RTX 2080.

Even if you are right with your statement, but "self-blame" is unfair, because you can't expect that every customer is an expert!

A 1070 mobile is not enough for liquid 4K play.

Shows every common benchmark. Even with halfway current titles, no notebook with this graphics card is over 20-25fps and that is not enough.

Far away, even 144Hz on the monitor are completely pointless, because you can't even reach a 60Hz with this fps number.

My laptop gives but almost the same picture again as my screen had before nem almost 1 1/2 years also cost 2300 euro. ^^ Will never be hot nothing can play everything on Ultra

I have read some of your comments below:

If your laptop RTX 2070 has managed 4k liquid, (I suppose not in Ultra Details), then theoretically, of course, the external monitor in the same settings run smoothly.

If that does not work, I'm assuming it's due to the bad HDMI cable (or the "incompetent" HDMI port itself).

If your laptop does not have a display port, you can only connect a "worse" monitor, as I wrote above, WQHD @ 60Hz or FullHD @ 144Hz.

Your laptop manufacturer has made a significant mistake, as the only one had installed HDMI port… With such power, it would have necessarily display port must be!

On ultra, nice. But not on 4K.

From FullHD to 4K, the pixels to be displayed quadruple, which massively costs performance (2.07mio to 8.29mio).

Which notebook should that be? In the net, I can't find a combination with 1070 in a notebook, which produces enough fps for 4K.

Yes I thought so too I've ordered a new cable as I said. I'm currently on vacation and can try it afterwards. Can I have this installed later or is it too expensive and too complicated? If I go down to 2560 or 1920 pxel the picture will be small that does not look so good. I do not know what that is.

I've read the comments and my answer:

Your laptop will not create 4K 144 Hz. By the way, HDMI only creates max. 4K 60 Hz.

For the money you would have gotten a very good PC that would have twice as much power.

If the image is smaller, if you switch to the 4K monitor on WQHD / Full HD, then you have to look in the settings on the Montitor itself, there should be a setting that he stretches to full screen while maintaining the aspect ratio.

My recommendation would be rather to send the monitor back and buy a WQHD / Full HD. (if still possible and if you can't solve the problems otherwise)
