Hi there! I know this is dedicated to LCD TV forum, but monitors are also LCDs, so I figured it wouldn't hurt to ask. There is a monitor out there - ASUS VG248QE made mostly for games, but its a TN panel with horrid colors. However, the G-Sync upgrade from nVidia replaces the monitor's PCB and the resulting colors and grayscale are of much better quality! I want to get that G-Sync upgrade but only if I know exactly how much better G-Sync colors are. For that - I would need someone with a colorimeter/spectrometer, VG248QE monitor, and G-Sync installed to take some HCFR or ChromaPure or CalMAN or any other software measurement readings! I am primarily interested in default (NOT calibrated) grayscale white balance, gamma, luminance, colorspace, 25%, 50%, 75%, 100% saturation sweeps measurements for RGBYCM, and if possible - ColorChecker measurements. I believe the name of the mode used with G-Sync is ULBM (Ultra LightBoost Mode),
Taking all these measurements alone shouldn't take more than a few minutes of your time and would greatly benefit me and many other people who are thinking about buying this G-Sync upgrade for this monitor and maybe others too. Your help would be greatly appreciated!
Install notes: Pretty ez install. The brown clip that holds the ribbon cable in place to control the buttons was a bit tricky to get opened, but once opened, it was easy to get installed.
Monitor notes: Pretty nice looking monitor all in all. I stuck the large G-Sync logo sticker over the goofy looking 3D logo on the base of the monitor. (More about the uselessness of 3D later in the post)
Before I get into color profiles and the numbers, lets take a quick look at my system specs:
AMD FX4350 Quad Core 4.2GHz - Processor
ASUS M5A99FX Pro R.2 – Motherboard
PNY GTX780 OC 3GB DDR5 – Graphics Card
Corsair Vengeance 8GB (2x4GB) dual channel running at 1600mHz – Memory
Antec 750 Watt - Power supply
ASUS VG248QE 24” panel with G-Sync DIY conversion – Monitor
The software to adjust the settings in the monitor is called SoftMCCS. It’s a free download and very easy to use. There are a number of posts on how to sue it. It is a free download from:
This stupid forum wont let me post links ... FAIL just google SoftMCCS
Before we get to the color settings we need to discuss refresh rates. The refresh rate that the monitor is set at controls the saturation and color depth of the colors. The faster that the refresh rate is set at, the colors become more and more washed out. I initially ran the monitor at 144Hz when I first had it. I thought it looked terrible, and the reason why is that it did. At 144 frames per second, the colors are so washed out that even the darkest blacks look grey and most, if not all, contrast is lost in whites. So then I ran it at 120Hz for the last 5 months or so. I REALLY liked the increase in color depth going from 144 to 120, though I have to say, I was never able to get the colors exactly right. It always appeared washed out. Games looked great … the desktop always seemed greyed and washed out a bit. I color matched an old studio Samsung monitor that I had been using. I had never considered running this monitor at 60Hz… after all it’s a new high refresh rate monitor, right? …. I should run it at 120 for sure.
About 2 weeks ago I tried an experiment. Because the new Sid Meyers Beyond Earth game will not allow you to run a high refresh rate monitor in full screen, I tried dropping the refresh rate of the monitor to 60 HZ to test if that would let me run the game in full screen (the answer: it does not). But once I had switched the monitor to 60Hz, I couldn’t believe my eyes. All of the color depth that I was hoping for in this panel was finally there and blacks are JET black and whites, bright and poppy.
So … I began weighing the differences between 60HZ and 120HZ in a display and what I came up with is:
The choppiness and lagginess that gamers perceive in 60Hz gaming is not a product of the refresh rate. It is a product of the video card not being able to output constant frames out at a steady rate. G-Sync deals with this brilliantly and basically, long story short, if your system can run the game at 30Hz … that’s 30 frames per second, it will look flawless. No tearing, no stuttering, no input lag. Just super smooth games.
-So then the big question presents itself: Is the hit in color saturation and color depth that the monitor suffers from when going from 60Hz to 120Hz worth the upgrade in terms of having more frames per second? Ahh yes, and that’s where our conversation turns to 3D. For desktop graphics, 120Hz is completely useless. Even the highest refresh rate moves are 60Hz. (Hollywood standard is 48FPS and the new youtube HFR(high frame rate) standard is 60FPS. Then why the recent TV’s that do 120Hz or even 144hz? …. The answer is 3D. A 3d image (in active 3D like on a computer with powered glasses) is actually 2 concurrent 60Hz images running in alternating frames. The glasses have a lens that is actually a fast refresh rate LCD that puts up a black image on alternating frames only allowing one of the 2 alternating images through to each eye. The viewer is then able to see a different image in each eye. Thus needing a 120Hz refresh rate to accommodate the 60Hz movie shown in 3D.
Ok … what else is 120Hz for? … Gaming in 120Hz is exactly the same gaming experience, but you are getting more frames per second. In my experience, the human eye is not able to detect the difference between 60 images a second or 120 images a second. BUT…. The human eye is able to easily detect the difference between washed out colors and bland looking blacks. >> So then the big question presents itself: Is the hit in color saturation and color depth that the monitor suffers from going from 60Hz to 120Hz worth the upgrade in terms of having more frames per second? << I offer no.
I have gone back to games that I have played in the last few months and marvel at how much better they look in 60Hz than 120Hz. Even the loading screens look better because the blacks are true black …. The colors pop … just on the verge of oversaturation, but they look GREAT! As long as the GPU can keep up more than 30 frames per second, the game is absolutely smooth and perfect looking.
-Ok ok … color settings: This monitor can be very bright. The way that it is set out of the box was terrible. But trying to battle the overbrightness with the luminance slider doesn’t work well. It greys out the image a lot. The best way to battle the brightness it to lower the contrast slider to about 55. At 55, the middle greys show up and you see definition in light greys and whites. Then lower the luminance a bit to get it where you like the brightness. If you lower the contrast slider less than 50, nothing happens, the contrast slider only appears to work from 51 to 100.
The balances of each color are a bit of preference, but it’s important that they are not super out of wack. The ones that I list here I have been using now for 2 weeks since I went to 60Hz and it looks amazing. I can really say this is the best looking monitor I have ever owned. I had a studio IPS panel monitor before, but it was really slow and blurry in movement.
