About LCD monitors.

Post by Specineff »

I just moved, and my apartment complex seems to have faulty grounding that causes my computer monitor to flicker like when you approach a fan to it. Needless to say, the flicker is killing my eyes. Which is too bad. I love the monitor as it was a birthday present from Greg here.

My stepfather offered to get me an LCD from Circuit City, but my worry is response time (I heard 16 ms is good) and native resolution. Meaning, I don't want to get blurry trails or have the game area displayed as a postal stamp in the middle of the screen, particularly with Dreamcast games.


Can anyone give me any pointers?

Thanks.

16 ms was considered mediocre several years ago (12 ms was good), these days 8 ms for gaming seems fairly common. Although larger panels are still harder to make/find with good response times. Also, the advertised response time and the actual response time may differ significantly, so make sure you read actual product reviews of the model before spending the cash on the display.

And don't neglect to verify the manufacturer's dead pixel policy.

Since native resolution is always going to be larger than optimal for console gaming, it's also good to look for a high quality built-in scaling chip on the monitor (relatively rare...) if that's what you intend to use the monitor for.

*shrug* Best Buy has a few that advertise 5ms. Then again, these are brands I've never heard of.

Currently, I use a Dell Latitude laptop, and find that using the LCD takes a bit of getting used to. It's perfectly fine for games, but it's still nice to output to a normal CRT every once in a while. Things just seem...warmer...on a CRT.

Ignore these ratings. Most of them are bullshit.

Once apon a time they used to rate refresh based on white-to-black-to-white-again. These days they measure them in grey-to-grey. "5ms" has just as much meaning as "really good". It's totally subjective to a lot of different things. Consider it a marketing term only, and thus utter crap.

The best way to judge these? Bring a console in and ask to test it on the TV. If the salesperson doesn't let you, then they obviously don't want your money and you should shop elsewhere.

I wonder if a line conditioner might solve the problem entirely rather than force you into buying a new monitor. Companies that make UPSes also make these devices (APC, CyberPower, Monster Power), which filter the power coming from your outlet and provide even, clean power for your electronics. Not sure if this would help a grounding issue, but it might be worth looking into. You could run all your consoles/PCs through it so your apartment's issues wouldn't affect them long-term.

1) Do you have a standard TV arial plugged into the TV and

2) Does the problem go away if you remove it?

I've got a bad groundloop at my place when I have more than 1 TV plugged into the main arial (enough to zap me when I touch my VCR downstairs in the games room!). If I take the arial out of one of the TVs, the problem goes away for both.

I also recently made myself a cheap diode filter and problem solved.

No. Cable. I only had the computer and monitor off. Even the AC was off. Oddly enough, my TV doesn't get affected.

Any more info, guys? I don't want to have my DC display games in a stamp-sized box. Nowadays it's hard to find a 1024 by 768 LCD with an 8ms response. All there is out there is 1280 by 1024, and if that's going to be a problem, I'd rather find another option. Thanks.

Ignore the fact that it's on a fighting game forum. Games are games, and we all face the same issues.

Gotcha. That's no problem. I have a dedicated RGB monitor for those systems. It's only the DC being displayed in a tiny 640x480 box what concerns me. Will an LCD monitor scale it up? I might to to the store and bring my DC and VGA box just to make sure.

Read the link above. HDTVs will scale any signal to full screen, but sometimes there is a serious performance loss that goes with it. When playing a movie, this doesn't matter. Who cares how much lag there is between your DVD player and your screen as long as the audio and video sync.

Wiht games, it's a different story. Audio and video might sync, but there could be a half second lag between your inputs to the game and what's shown on screen, and that's all bad.

Again, read the thread I linked to. It's very helpful, and recommends better brands that support scaling and "game modes".

So even LCD computer monitors will suffer from that? Pffsh. Well, the DC outputs 480p, so according to that document it shouldn't be a problem. I'll test it with a monitor in the internet room of my apartment complex.

I might as well buy one of those Wells Gardner monitors that support both RGB and VGA up to 640 by 480 and be happy with it.

I was going to suggest just that, but every time I do people whine about wanting their big/wide screen LCDs and Plasmas.

IMHO, analogue still is king. CRTs produce a much better picture, and for folks like us who tend to play games on older systems, 4:3 CRTs give correct aspect ratio, and superior pictures at low resolution.

With a WG monitor you can use RGB/SCART output from old consoles, or RGB/VGA from new consoles, and the picture will look superb. Slap it in a wodden box with carry handles and fan-forced cooling, and you've got a superb quality monitor that's easy to rotate, and safe to use.

Plasma is nice for watching DVDs on. LCD IMHO looks ugly no matter what you do with it. Both suck for playing games.

Me personally, I'm waiting for OLED before I move away from CRT:

I predict that in a few years there will be a big CRT renaissance -- in fact some would say it's already started to happen. It's like the 1990s revival of analogue vs. digital music kit all over again.

Back on topic, if you want an LCD that can best display DC VGA and other such games, it's best to look for the rare but extant models with a native resolution of 1280 x 960 -- that is, exactly double 640x480, meaning all the monitor has to do is draw four pixels for every one in the input. Simple conversion, and virtually no conversion artefacts, as the input signal is a direct fraction of the native resolution.

Thanks for all your info, Elvis. I take it that if I try to feed a WG monitor an 800x600 image from my computer it will not take it, right?

Eps, a 1600 by 1200 monitor is about five times the same rez as 320x240, and 2.5 that of 640x480. Would a DC look like ass on it?

According to both the BYOAC kids and RetroBlast, 800x600 is hit and miss with WG monitors like the D9200. Some will do it, some won't. Officiaiily speaking, 31KHz is the maximum res th emonitor can do, which means 640x480@60Hz progressive scan. Anything over that is considered "overclocking" and probably not good for the longterm health of the monitor.

Um... pass, as I've never been lucky enough to use an LCD monitor that high-res ;) I'd guess that it'd be reasonable based on the small pixels making the conversion less obvious, but really that's just pulling an estimate out of my behind. Anyone? :)

640 X 480 VGA looks best on CRT's, by far. Try running windows in 640 x 480 on a 1600 x 1200 LCD.

Yeah, but my CRT is killing my eyes due to some faulty grounding or something over here at my new place.

End results will wary wildly depending on the quality of the built-in scaling chip on the LCD. Also scaling something polygon-based, like Under Defeat, tends to look a lot better than scaling 2D desktops or equivalent sprite-based games.

I tested my DC with poly-based games, and though I prefer the crystal clear image of CRTs over the "glassy" look of LCDs, it looked great. The only problem was the aspect ratio, but that's because the monitor was one of those strange 1280 by 1024. Which are almost square. I'll get one of those 17 inch 1600 by 1200 which is the correct 4:3 aspect ratio.

On the other hand, the monitor might just be very sensitive to EM interference (it looks almost as when you get a fan close to one). So I might head to a thrift store and test one here. Preferrably a Sony or a Mitsubishi.

About the desktop, TF, there's no need to scale if the video card in my system can output it. And it can.

Hey, now that's cool. OLED is having all sorts of issues getting product life up to reasonable standards. SED looks like a winner!

ya, those wells & gardner crt's would be perfect. If you're able to make a good enough case, or know someone who can, then go for it.

I've come very close to purchasing one of those but always hold back because I know I'll never have a decent enough case for it.

peace,

As much as I get excited by all these new TV screens, I can't help feel let down by the constant barrage of new technology that never seems to make it to store shelves.

Plus everything is pixel/digital-based these days, and that sucks if your input is a different resolution. Say what you like about analogue technology, but at least it's semi-adaptable to old and new formats.
