Not quite actually, imagine I want to represent a sine wave by shifting the display colour between full white and red, it tracks nicely and I start to increase the frequency of the sine wave I want to represent, as the frequency increases the displayed version of my signal can't keep up and it never goes fully white or red.

The amplitude (colour) will start to drop as the signal has peaked and started coming down before the display can get there and it gets worse the faster it gets until I just get a shade in the middle.

If I have the frequency set to 60Hz and I have a 1/60th response time then it will look normal and start to cause jagged edges beyond 60Hz (as the refresh rate means only part of the screen updates before the next frame starts to render) which happens with any monitor.

However if I have 60Hz but the panel response is 1/40th of a second I will get the result I talked about above up until 60hz and then I will get a mix.

---------------------------------------

A real life example if you have a building on a blue skyline, you move the camera so where the building was there is sky, for a brief instant you will have a ghost image of the building in the sky where it is not fully blue "ghosting"

The difficult part of this is the response time for moving from one colour to another will be different from going to one colour to a similar shade.

A display may not ghost if the sky is blue and the building is grey but it will ghost if the sky is a different shade of grey.

Grey to grey is considered a worst case scenario, so you will get the worst response times here where as white to black and back is considered best case. This is caused by the voltage difference between the starting colour and finishing colour is what drives the pixel to change, the smaller the distance between the colours, the lower the voltage applied and the slower the change (offset somewhat by the fact it has to change less).

Depending on the properties of the panel the curve of response between these two points will be different.

-------------------------------------------

TL/DR: Slow response times cause ghosting and you can't represent a panel with a single response time figure.

 

Afirmative. I was keeping it on the simple side but that's a much better explanation than mine. I didnt address ghosting at all.

 

Alright, that is FANTASTIC to hear that it is indeed 120hz, repped.

 

HWMonitor reports my Corsair at max temp of 176C for a few seconds...how is that even possible?

 

Can you run AIDA benchmarks please and post it? AIDA dedicated Memory Read/Write/Copy/Latency and AIDA CPU/Cache test

P.S. How did you change it to T1 from T2 CR? I do not see the option, is it the Prema bios option?

 

yes, you can change it via Prema MOD, but the option is also available in XTU sure, can do AIDA as well, just give me some time.

 

I am after a little advice regarding my CPU on my P775DM2 overheating. At idle it is at 45 - 50 degrees but while gaming it is as high as mid 90s. I have cleaned the heatsinks and re-applied IC Diamond but that seems to not have made much difference so now I guess I am looking at undervolting. In BIOS I have the option to offset the CPU core voltage by as much as -500mv. Is this where I should be starting?

 

Yes, but please not @ -500mv! Starting point should be at -100mv. From that on work your way up till you get crashes! Dependent on your chip you should be able to reach -155/-185mv.

 

Thanks. I'll try it tonight starting from -100mv.

 

should be obvious, but im still gonna say it: if -100 mV turns out to be unstable, dial it back down in -5 mV intervalls good starting points for stability testing are OCCT large data set, Prime95, 10 consecutive runs of Cinebench R15 / 11.5 and XTU Stress test. Aside from those, ull want to check your usual tools and programs to ensure everyday stability

 

Thanks for the advice. While I am not a complete compoota noob I have never played with changing my clocks or my voltages so any advice is welcome.

 

Thanks. I am failing to set T1 with these settings (screenshot). And I am not sure x22 multiplier is read correctly.

 

youre aware that youre trying to set 2926 mhz (22 times 1.33) at CL15 and command rate 1 right? seems very tight if you ask me ^^

Wrong topic -_-

 

I would go off the BIOS for memory clock speeds if the setting is open.

 

How good is the P775DM3-G? Ive found a good deal for it: http://www.laptopsdirect.co.uk/pc-s...16gb-2tb-256gb-ssd-n-pcs-l1120038/version.asp

Its a crazy amount of money to spend. I've heard it has heating issues and is really loud is this true? The reason i'm asking is because im trying to decide between this and the P670RS-G which is a fair bit cheaper but obviously not as strong. Is the price difference worth getting the P775Dm3-G?

 

That's actually a really great price for it and if I were you, I'd get it. While it is lacking the 6700K, after a bit of taming, the P775DM is a monster. Most of these monsters can be "loud" but these are desktop components in a DTR package.

 

The CPU it has is still pretty strong right? And by taming you mean underclocking?

 

why would anyone buy a high end CPU and underclock it?!!!?

He means undervolting it to get lower temps while still providing the adequate voltage for the CPU to operate fine at the selected frequency

 

The 6700 is no slouch but it is locked down. The good thing is you can always get the 6700K for a great price now that Kaby Lake is almost here or you can even wait for Kaby Lake if you ever want to upgrade your CPU.

And what I mean by taming is undervolting to get better temps. The better temps will allow you to run the computer in automatic fans which aren't bad sounding at all. But we are here to help you, so don't be afraid to ask if/when you get your monster. BTW, Phoenix may be a little heavy-handed but he's another great guy that will help you when you need it.

 

Cool thanks Yeh gonna have to make a quick decision as the deal is only for the weekend. Annoying as its a huge amount of money Another up side of this laptop is g-sync which sounds good

 

Don't get your hopes up. That FHD display is good compared to non-Gsync laptop displays, but garbage compared to a desktop G-Sync display (if you want smoother games and dont care about colors)

 

Depends on what display you are comparing it against. A regular one or one that's a significant fraction of the machine in cost.

 

Am I the only who have problem with GSync? In a lot of games it just dont feel smooth. When fps drops from 75 fps it makes the game stutter less, hower 75 fps feels smoother with GSync off.

 

I have compared the built in LG fhd Gsync screen to a $300 Acer 144hz FHD Gsync monitor.

Maybe the reason why mobile GSync is noticably worse then desktop GSync is because of the implementation. Desktop monitor use a separate GSync scaler unit with its own memory buffer (768 mb if I remember correctly) to sync the panel, however laptop panel just use software to utilize this fuction which is part of the eDP. Probably another reason why newer drivers released by Nvidia makes the games more blurry with the same fps then with the latest driver from Clevo. Nvidia probably optimize GSync for the scaler unit while clevo optimize it for the eDP.

Also when frames change fast suddenly the reason why there is much less stutter with a desktop monitor is probably because it can initialize frame doubling more efficiently thanks to the local frame buffer in desktop monitors.

Comparing 75fps/75fps laptop/desktop, for the above reasons frame change is less noticable on the desktop monitor. Not to mention the less ghosting and smoother frames because of the much less response time and double the refresh rate.

So if you want an fhd lapto GSync panel, it will be better than the similar non Gsync panels, however it will be not perfectly smooth as a desktop variant. Also many games (expesially with game ready Nvidia drivers) do not support mobile GSync correctly so you may experience frame skipping, rendering problems and many games with ingame VSync will not detect the highest refresh rate correctly. Most problematic games on the fhd GSync panel are UWP games running Unreal engine. Windowed Gsync+fhd gsync combination in these games (GoW games) result in terrible frame skipping. They are palyable, however the frame skipping caused by mobile GSync is annoying which will ruin your experience.

Newer GSync panel (3K auo panel) maybe better, however if you stay with the LG IPS GSync panel, then be prepared for the above.

tl;dr: GSync on laptops WORK, however they are not as good as the desktop variant.

 

I find the gsync behaviour to be the same as on my x34. The only games I have experienced stutter on are UWP games (especially Forza horizon) as the implementation is complete and utter crap. But the same stuttering is present on my x34 if I drop settings to be running at the refresh rate of 100hz.
For the UWP games I regrettably own I set the in game fps limit to lower than the screen refresh to get around the issue and intend to never buy any more.
I thought the issue was dx12 related and the fake fulsceen it uses but the division has just been updated to dx12 and is still super smooth either at 75fps or lower.

 

UWP platform is crap+Windowed GSync is crap. I found UWP games playable with my desktop monitor when nothing else was on the screen, however as soon as something basic as the volume bar appeared on the screen when I pressed volume on the kb, the game stuttered whem it appeared and when it disappeared, so even as basic as that affected windowed GSync. Windowed Gsync is still full of bugs and uwp games can only use this which is pathetic considerinf their price.

As for The Division. Patch 1.5 made things worse for me. Horrible stuttering when PCS or HFTS is active, when these are active, the game will have terrible microstutter when rotating the camera. Okay when I am running around, however if I start panning the camera it looks terrible. Mostly smooth when it is running with 75 fps, however 65 fps with PCS or HFTS is worse then 65 fps with High shadow.
Also, the DX12 api has been taken out from the final patch. Probably because the really good fps icrease which it made was caused because HFTS got disabled in the background with dx12 api.

 

That's interesting, the first time I loaded up 1.5 it was a stutterfest (on my x34) but then dissapeared after a restart - but I may well have changed from pcs back to the next highest at the same time as that's how I run it on the x34. On the laptop screen I usually turn it back on but may not have... I will check later.
Any gsync issues definitely seem to affect my x34 the same as my built in screen though.

 

What was your VSync setting in NVCP? VSync in the Division is now broken (as well custom refresh rate) and will cause stutter fest.

 

I have vsync turned on in nvcp and turn it off in all games, I find this gives the least issues although means I have to have custom settings for benchmarking software to disable it.

 

Have just been playing for an hour or so with pcss and also tried with hfts and it is smooth, no issues at all - just like in previous versions. With pcss I mainly stay at 75 fps with the odd drop into the 60s and with hfts it mainly stays around 65 with drops to the 50s and sometimes reaching 75. But it is always smooth with gsync working as it should just like on my x34.
I have gsync enabled for fullscreen and windowed and as mentioned earlier set vsync on in nvcp and off in game.

I really notice stutter a lot and hate it! For my sins I have had an Asus pg278q, Asus pg279q, Acer xb271hu, and now the x34 and can't stand playing without gsync any more. For me the 75hz screen I have performs just as well as all of the above desktop monitors in terms of gsync and I'm also impressed that the pixel response isn't really noticably worse than the above IPS screens in real life use either despite being a lot worse on paper - they all have massively worse pixel response than the TN pg278q in real life use though, again despite what some say on paper....

 

What I am seeing is not actually stutter, its like a bug with AA and the edges flicker/shake when I turn the camera if PCS/HFTS is active and the FPS drops under 70.

 

Hi, new(-ish) P775DM3-G owner here.

I have a few questions regarding BIOS/EC versions.

Right now, I'm using EC 1.05.03, 2nd EC 1.05.02 and BIOS 1.05.03. Judging from what I could find on the web (especially this thread), the only "outdated" one is the BIOS and the current version is 1.05.06, right?

 

Has anyone had any dead pixel issues with the 3k 1440 screen?

 

Just like any technology in the screen, you are prone to have it. I paid an extra fee for 1y no dead pixel guarantee at PCS

 

I've not seen any reports it is particularly worse than other panels for dead pixels however.

 

In case anyone is looking for the full package: It is available from Clevo's public Asian FTP. All it takes is some minor link editing.

Not sure if it is okay to post deep links here (probably not), but in case anyone needs it, just drop me a PM.

 

Sent pm.

 

Some of the keys are quite squeaky, especially the space bar. Anyone with a similar problem?

 

hi my friend I want to ask you about the temps cpu and gpu
I want to pull the trigger too for this
I heard about a problem with fan profiles
thank you

 

Intensive gaming or computation operations will generate more heat. If you use MAX profile, it will be loud and relatively acceptable temps. How loud? I wont be able to sleep with it in the bedroom.

On automatic, you are risking to get into the 85-95C peak range.

 

so you think its better to look the p870dm with single 1080??

 

you mean the P870DM3

If you undervolt the CPU a bit, you can tame the temps easily. I've done this on @Shakeeb Anjum laptop and even managed to overclock it to 4.4 GHz on all cores with very nice temps.

If you get the laptop from HIDevolution, they use the X Cross Method when applying IC Diamond which greatly improves the temps. Their EVOC laptops also will get the Prema BIOS/VBIOS for free as soon as their finalized.

How easy is it to move the setup into RAID 0? I've never done it

 

Taming temperatures is the main reason I'm considering the Portuguese obsidian-pc for my P775DM3.
I'm not afraid of repasting with better thermal pastes than stock, but delidding CPUs is something else entirely and I am glad they offer this service, even though it's a bit harder to fit in my budget than other European resellers.
Still, I believe it will be worth

 

Dead pixels have been less of an issue with this screen... The main issue has been with the way the pixels are handled by LCD controller or something like that.. people have had weird pixelation issues.. its not noticeable at a distance but close up it is.. Mainly been with this screen on P870DM, not heard anything on P775..

 

I never see any pixelation at normal viewing distance. Only if you come so close to the screen will you see the lines which isn't how I use or anyone should use their laptops anyway. This is the best screen I've had on a laptop

 

I ordered the P775DM3-G with the GTX 1080 and my seller is not sure about the HDMI output.

I need to know if the HDMI output is 1.4 or 2.a.

I will use HDMI 2.0a for my 4K and HDR.

Someone can help me confirming this?

 

Good question.
Euroccom and mysn say 2.0, but other say 1.4b. Don't know who to believe as i don't have a 4k tv to test.

Question : where can i find lattest bios and EC ?

 

Exactly there are diferent informations about the HDMI port.

Even if it's the HDMI 2.0 it won't work with my screen which is HDR.

Any confirmation of this?
