I have tried some other forums, but no luck. You are my only hope ...
Here are my specs:
PC = Gateway SX2800 (http://www.gateway.com/systems/product/529668287.php)
Processor = Intel® Core™2 Quad Processor3 Q8200 (2.33GHz, 1333MHz FSB, 4MB L2 cache)
OS = Genuine Windows Vista® Home Premium (64-bit) with SP1
Memory = 4096MB 800MHz DDR3 Memory (2 x 2048MB Modules)9
Motherboard = Systemboard with Intel® G43 Chipset + ICH10
Video = Integrated Intel® Graphics Media Accelerator X4500 (VGA,HDMI)
Video Driver = v. 220.127.116.119 (upgraded from factory install 18.104.22.1686)
Monitor = Asus VW246H. VGA,HDMI,DVI. HDCP (http://usa.asus.com/product.aspx?P_ID=zMRyN4KB5o5rSqKr&...)
Here are the facts:
1) I have both PC and monitor powered down. I connect HDMI cable as the only monitor. Power up. Monitor is on HDMI input, and reports "HDMI NO SIGNAL" with a blue screen.
2) Asus monitor and HDMI cable video and sound work fine when I connect it to my Roku video streaming box.
3) VGA input of Asus monitor works fine.
4) I connect a dual display with an old VGA monitor as primary display extended to Asus HDMI as secondary. Intel Graphics proerties window shows that both displays are detected: "monitor" for VGA primary display and identifies Asus HDMI display as "digital television". But I still have the "HDMI NO SIGNAL" with a blue screen.
5) The PC came factory installed with Intel driver 22.214.171.1246. I upgraded to latest driver 126.96.36.1999. Both drivers see the "HDMI NO SIGNAL" with a blue screen issue.
Here are my questions:
1) Does anyone know what is going on?
2) Does anyone have a driver for x4500 that works with an HDMI display? Should I downgrade?
I'll be trying to connect the SX2800 to a ViewSonic lcd tomorrow afternoon (Tuesday 9/01/09). I'll let you know how it goes. As in your case, it worked fine today with the VGA from my old system. UPS is bringing the lcd in the AM.
Whew! I got the LCD working, but it was such a prolonged process there's really no way to retrace all the steps I took-- many (most) of which were pointless anyway.
But everything came together when I had both the VGA and LCD connected (and receiving signal) at the same time, and out of sheer frustration right-clicked the mouse. It provided a menu that, in coordination with Intel's GMA X4500 menu, allowed me to finally designate the LCD as the default, and bring the LCD up to the 1080p resolution. Now I'm still trying to understand why the volume on my LCD speakers is so very, very low. I wish I could be more helpful! Good luck!
Weirdness. Like I said before the Asus worked with the HDMI connection on my Roku video streamer box - so I didn't think it was the monitor.
Ended up getting a exchange on the Gateway SX2800 - thinking I had a lemon graphics card. New SX2800 had the same issue - blue screen.
Out of frustration, ended up trying out a brand new Samsung 2494HM and a brand new Viewsonic somethin-or-other. Both worked immediately with the HDMI connection!!! Plug and play!!!
Sent the Asus back - very annoying - who knows what the issue is. Kept the Samsung, looked better than Viewsonic - it also has a switch to correct for HDMI overscan(desktop extending past the screen), since the intel x4500 does not have any corrections for that. Hope this helps somebody.
I have a 720p HD Panasonic screen. I intend to hook it up to the SX2800 desktop CPU through HDMI to play my movies. I don't know if that will work?
The saler told me that the Integrated Intel Graphics Media Accelerator X4500 in the CPU won't give good video quality on big screen is I'm still hesitating to buy it.
If you buy the SX2800 you'll very likely want to upgrade the graphics. The X4500 is suitable for standard definition, but not HD. Intel created the x4500hd in an attempt to meet that need. The Vista performance ratings on the stock SX2800 include a 4.0 and a 4.5 of a possible 5.9 on the graphics components. All other ratings are 5.9.
You face two problems when trying to upgrade the graphics. The worse of the two is that the power supply in the SX2800 provides only 220 watts. The power supply is a unique shape, so most aftermarket supplies won't fit. I've read that an upgrade of the same shape is only available through Acer (which owns Gateway). The second issue is the SX2800 is so small that only low-profile graphics cards will fit. There are a variety of low-profile cards available, but they cost a bit more than their full-height twins. So you're stuck looking for a low-wattage, low-profile card, and at a higher price.
I've read a lot of user reviews in which people say they've successfully installed a card that's stated by the manufacturer to require more power than their computer's power supply can provide. Best of luck to them. I chose not to do that. Like you, I want to use an HD display to its full advantage. I'd already bought the SX2800, and I hate returning things. The small size wasn't a selling point for me, so my solution was to transfer the guts of the SX2800 to my old mid-tower case. Then I bought a standard 700 Watt power supply and a full-size, high wattage graphics card. I had to replace a SATA cable with a right-angle SATA cable in order to get the graphics card in place. (It's possible that a low-profile card would also require that extra space.) The motherboard of the SX2800 is pretty basic. I may choose to upgrade at some point. I'm very happy with what I have now, but I certainly wouldn't recommend the path I took to anyone!
In summation, if your focus is quality full HD buy a different machine. This is a great little computer. It's extremely quiet and fast. But adapting it for an HD screen is more difficult and/or expensive than most will want to undertake.
I am no expert withaudio/video but I am (usually) pretty good with PCs. I have a legacy Sony KF-50WE610 LCD with no HDMI inputs. I upgraded my receiver from a Denon AVR-2106 (piece of garbage, whined and cut out every few days) to an Onkyo TX-SR607. I plugged my new Gateway SX2800 using HDMI out to the TX-SR607, then send the HDMI out of the receiver to the Sony TV's DVI input - Vista splash screen starts with the scroll bar then poof, no video. If I hook the PC directly to the DVI input, I have a pretty bad picture, but a picture. I am using the same cable. I have called Onkyo several times and they cannot seem to understndn why there is a problem. I was told to hold down the 'display' button and I can see the resolution coming from the PC and what the receiver will support. It alternates between 60/1080 and ---. I have updated to Intel's latest drivers. I am thinking the TX-SR607 is going back because it also fails to power my Klipsch powered subwoofer. The best part of all of this is that everytime I unplug an input to try and force the resolution and refresh rate change for my TV, it resets back to nothing. I can't get both displays to work (VGA) and the LCD at the same time. I am really disappointed. If anyone has any ideas, I am all ears.
I'm experiencing a very similar problem with my new HP p6240f with the Intel GMA 4500X graphics with DVI-D. It has worked using two monitors but now does not. I spent two hours with HP tech support and wound up returning the computer to Office Max. I'm having the same problem with the replacement computer.
I'm running Windows 7, so that doesn't seem to help when discussing things with tech support. I'll keep trying!
I was able to get mine working, but not the way I wanted. I was using HDMI from the PC to HDMI on the receiver, then HDMI to DVI (or vice versa) from the receiver to the TV. Apparently, there is a loss of data when making the transition from HDMI to DVI so my TV wasn't getting the information it needed. I changed graphics cards and was at my wits end when I decided to just hook the PC straight to the TV. It has a good picture for what it is, but I had use another cable to send the sound out of the PC input to my receiver's analog audio connection. I am annoyed that I spent so much time trying to figure this out. It will all be corrected when I buy a new TV with HDMI input but that isn't going to be anytime soon.
