Acer XB270HU 27" 1440p 144Hz G-Sync IPS ULMB Discussion Thread - Page 96

post #951 of 4031
I installed my XB270HU this afternoon. Been playing around with it for a few hours now.

No dead pixels. No stuck pixels.

This is my first IPS screen. I think I now know what "IPS glow" is. It is not noticable on the desktop, or in games. But when I use this website and set the whole screen to black (select black, then press F11), the whole right lower part of the screen gets a yellowish glow. The weird thing is, when I move my head to be directly in front of the right bottom corner (still same distance), the glow becomes a lot less. So it seems this IPS glow is depending on the viewing angle. Weird. I had expected that an IPS screen would not change its image depending on the viewing angle, but it does. Even on the parts of the screen where there is no IPS view.

Colors seem nice. I can't compare to my old screen, because it's disconnected now. I'm gonna order a Spyder 4 Pro, so tomorrow I'll calibrate my screen. Only then is it fair to compare screens. I still use nVidia's Digital Vibrance. I loved that with my TN screens. I used it at 70% on my previous screen. It had reset to 50% (the default, I guess) after I plugged in my new screen. Good enough. Again, I'll mess with colors more tomorrow.

Scaling is gonna be an issue I need to get used to. Letters are small. Using Windows scaling seems like it just messes up everything. Changing fontsize in my browser (PaleMoon, aka Firefox) changes fontsize on some letters, but not all. It gets ugly very quickly. So atm I just run in true 1440p. My eyes aren't the best anymore, but still good enough for these tiny letters. Let's hope it stays this way for a few more years.

I found out not all games support 1440p. E.g. The Old City Leviatan does not allow me to go above 1920x1200. It's using the Unreal Engine. Editing config files does not work. I mess with The Witcher 1, to test ULMB. It works, but I can't get TW1 to do high framerates outdoors. If I enable vsync, it stays at 55-60, and only sometimes goes to 70. Indoors framerates can reach 300. Really weird. I wanted to try UT99 with ULMB (the last shooter I played online). UT99 does also not allow resolutions above 1920x1200.

Testufo says it will detect your framerate automatically, if it is 120Hz. Unfortunately the XB270HU does only do ULMB at 100Hz or 85Hz. I haven't found an option to configure framerates in the testufo webpage. So I can't properly test ULMB there. I do see ULMB @100Hz configured on the desktop removes ghosting, but the little ufo moves very choppy. Would be nice to be able to test it when the ufo moves at 100Hz too. Even when I set my desktop to 120Hz (without ULMB), the testufo page keeps running at 60Hz.

I like the OSD of the XB270HU. It's a lot easier to use and navigate than the OSD of my 3-year old Asus monitor. Still it seems a lot of work to switch between ULMB and non-ULMB on the desktop and games. I wish the nVidia controlpanel would allow me to configure both G-Sync, ULMB-settings and refreshrates for each game, and also explicitely for the desktop. Right now, desktop and games refreshrates seem to be connected. And ULMB requires you to press a button on the screen (which will break some day). It would be so nice to have all this configured once. It would also be nice to configure the brightness differently for ULMB and non-ULMB.

getting a modular corsair pro psu that retails for 140 for 60 after the bitcoin mining hype fell through was a sick steal

I still have some questions.

1 - Which pixel error norm does it have?
2 - Is it possible to switch the refresh rate?
3 - Is it possible to go for 120herz and ULMB like on the RoG Swift?

1 - I don't know what you are asking?

2 - Yes, through Windows

3 - No, it only supports 85, and 100 Hz for ULMB. I believe its response time is a bit too slow for clear 120 Hz (this is probably why the Swift doesn't do ULMB at 144 Hz too).

The x-rite colormunkie is the only cheap worthwhile colorimeter, plus it can be used with dispcalgui+agyrll which is free as well as one of the best programs for calibration.

Nevermind that i've used both the S4P and Colormunki on multiple identical monitors (4, at one point, while I was deciding which ones to send back due to dead pixel location) and the Colormunki managed to somehow give completely ridiculous, different results over 3 (identical) of the monitors as opposed to the S4P in similar lighting conditions. I'm not the only person that can attest to the results of the x-rite in that way, either.

Also, the S4P price has gone up since I bought it, which I also mentioned in my original post about it. At $89, it was an absolute steal. It was also at $119 a few months ago. If it's the same price as the Colormunki then I implore people to actually use the damn things and see which one provides the better results for their own monitors. I don't need to link to blogs and sites from professionals; most people who've never even looked into colorimeters obviously don't need that level of accuracy from their monitors (i.e., professional use cases), and that was my point. I never ventured into the whole, "hey, let me tell you all about colorimeters and how there are a myriad of options ranging into the thousands of dollars to properly calibrate your gaming monitor which, obviously, you have no professional uses for, otherwise you'd likely have already purchased an entirely different monitor altogether and already have the necessary equipment to calibrate such a display." My argument was always based on the, "hey, OSD and eye-ball calibrating sucks, here's a decent, cheap solution that has worked for me." Keep beating the "this is not what x and y site and company use so your opinion of the z product is invalid" drum though. The people likely to invest in those options aren't looking to OCN to give them that advice.

You'll also find the same level of "credible sources" scattered about the internet praising the S4P and similar products as much as you will the x-rite, but I digress. Now i'll really stop replying to you, as you've got it all figured out. I'm just here spewing my garbage opinions with no basis in reality, don't mind me. thumb.gif

PLUS +REP to both you guys thumb.gif

Without intelligent/detailed discussions like this, many people wouldn't know where to start with their research and hopefully leading to the best bang-for-buck giving their situation and personal preferences wink.gif

THIS^^^^ +R ... surprised you (Tuba) didn't add this to the discussion as you have in the past wink.gif

Hey guys, I've been thinking about getting this monitor but I tend to switch from my gaming pc to my work macbook. Will this monitor work with macs if I use a displayport to mini displayport/thunderbolt cable? I dont care if the g-sync works when plugged into the mac since I'll be working on spread sheets most of the time.

But then alternate.nl also said that they were not sure that they (alternate.nl) would ever sell that monitor themselves ! Really weird, international organization, and they decide to sell some top-end products in some countries, but not in other countries.

Alternate.nl was good 10 years ago, now its one of the worst shops in the netherlands whent it comes to service. Only buying fans there if i need them and no one else has them in stock. People working there have no clue about hardware.

IPS Glow seems bad.
This is my first IPS screen. So I don't know what is supposed to be normal. I play a lot of dark games, and the glow is so noticable, I can't believe people would find this acceptable. There is a little IPS glow in the 2 top corners. Bottom right is getting worse. But the IPS glow in the bottom right is really heavy. Basically in dark games, the right bottom corner is more yellow than black ! It's not only distracting, I can't even see well what's in the game in the left bottom corner. Also, if I move my head slightly, the exact location/edges of the glow moves around. I find this 10x more distracting than any TN color-shifting I've ever seen.

I can understand that people who play bright games, or do other stuff than play games, like the colors on an IPS screen. I like it too. Especially the lack of color-banding. Color-banding is most noticably in dark games (at least, that is my experience). I played a few games (Outlast, Dying Light, Thief Gold, The Old City Leviathan, Vanishing of Ethan Carter), and when it gets dark (evening, night, inside a dungeon), the colors are nice. Except that lower right corner. But to be honest, I wonder how much is that because this is a 8-bit screen, and how much of it is because it is IPS ?

For those of you who have had/seen more IPS screens. Is this strong yellow glow normal ? I think I'm going to RMA this screen tomorrow, and try another one. But if this is normal, then an IPS screen is maybe not good for me.

Alright overclockers, I was able to access the service menu an second time. Still don't know how I did it, honestly.
But now I went through the whole Menu and filmed it, there is nothing interesting there. There isn't any option to turn off the LED or turn off the boot animations etc.

Did you turn brightness down on the OSD?

The monitor roughly being properly calibrated is around 20-26. The IPS Glow is bad when its set to 100 (What you receive it at)but when you turn it down to 25 its not nearly as bad as factory default.

But yes, most IPS have the glow, this one seems to have a yellowish tint for some reason however.
